Derbygate – still gaining traction
<intro>Government flailing around helplessly is never a pretty sight<outro>
As the curtain rises on the musical ‘Evita’, the character of Che Guevara comments sardonically, chorus-like, on the preparations for the funeral of Eva Peron. While I’ve never been much good at doing sardonic, Tim Rice’s libretto perfectly sums up the evolving brouhaha surrounding the award of the Thameslink train fleet contract to Siemens – leaving Bombardier’s Derby works with a gaping hole in its future workload: ‘Oh what a circus, oh what a show’.
This being a 21st Century circus, it is not a succession of separate acts under the firm control of a whip cracking ring-master. If only.
Instead we are seeing a variation of the Cirque du Soleil, where each act has a tenuous relationship to a ‘narrative’ running through the show. Just what the storyline is in the case of Derbygate is not entirely clear. But decades of Government disinterest in a national industrial strategy is somewhere in the mix.
Government inflicted damage has been a leitmotiv of my adult life. Industry after industry has been brought low by government action, inaction, malign spite, intellectual snobbery or, more generally, all round lack of nous and incompetence. So really, what we see going on in the railway industry generally, and rolling stock in particular, is par for the course.
But what is unusual is that this time Government seems unable to brush away the effects of its sins of omission and commission. If the Transport Select Committee hearing on 7 September was meant to clear the air, the only benefit has been to give the combatants better sight of the target
Siemens was declared preferred bidder for the Thameslink fleet on June 16. Bombardier announced the start of consultation on the resulting redundancies on 5 July As I write it is 9 September and the Daily Mirror has just run an editorial castigating the Prime Minister over the decision.
Meanwhile even our urbane Transport Secretary Philip Hammond seems hapless, or helpless. He is quite rightly adamant that the deal can’t be unwound. And behind the scenes his officials are looking at ways to get more work into Derby in the short term, including the proposal to add a Pantograph car to create a dual-mode class 22x Voyager/Meridian.
Crossrail
It has been obvious for a long time, at least to this column, that the three big Government-directed rolling stock procurement exercises – the Intercity Express Programme (IEP), Thameslink and Crossrail - were inextricably linked, even though those in charge saw them as self contained. For example, once
When a company puts industrial boots on the ground they have to be kept supplied with work. And while my old chum Alistair Dormer of Hitachi is confident of winning new business from European railways to keep his new Newton Aycliffe factory occupied, the reduced quantities involved in the IEP deal, plus the reversion to operator based procurement, flagged up by Tony Miles on page x, means that for Hitachi Crossrail is becoming a ‘must win’.
Guff
As an example of the unreality ruling within his Department, when questioned by the Select Committee on the importance of retaining a national train manufacturing capability, Mr Hammond replied that he would certainly like to see a viable train building industry in the UK and that ‘fortunately’ this will happen as a result of Hitachi’s commitment to its Newton Aycliffe train building plant.
But the Government also wants competition within the UK and Mr Hammond hopes that when considering future rolling stock tenders there will be ‘strong competition between British based manufacturers’ so that while there is competition, whoever wins the order, the trains will be built in Britain. For this reason he also hopes that Bombardier will remain as a thriving train builder in the

After Thameslink, there are no major main line orders planned. The Government’s much vaunted 2,700 new main line vehicles by 2019 is made up of current orders. The only outstanding requirement is the 530 Piccadilly replacement stock vehicles. So in Philip Hammond’s naïve scenario, Bombardier and

That seems a more likely explanation.
Optimists might take this as suggesting that the tender documents could be revised to favour
Suspicions
To recapitulate, under the Crossrail train service provision contract, the successful bidder will be responsible for building the new rolling stock and associated depots and then maintaining the trains. While ostensibly similar to the Department of Transport’s procurement of IEP, the capital cost of the Crossrail fleet goes onto Transport for
And according to Crossrail, under its deal it will be required to pay for each train ‘as it becomes available for passenger service’. So, the argument goes, by reducing the time between the start of train deliveries and entry into passenger service, Crossrail will achieve ‘significant operational savings’.
Yet Crossrail still intends to introduce the train fleet ‘progressively’ to the existing rail network ‘well in advance’ of the start of services through the central section. And all this vague talk of saving ‘tens of millions’ through a six month day didn’t ring true. Especially when, according to the Crossrail statement the scale of the operational savings expected remains commercially confidential ‘while the procurement process is ongoing’. In fact, with the
Nonsense
My suspicions were heighted by the implication in the statement that if Crossrail signed a contract at the end of 2013, it would have to pay for the trains when the successful bidder chooses to deliver them, rather than at a time determined by the customer. This has to be nonsense. The customer specifies when trains are to be handed over.
Putting back procurement reduces the time for development and acceptance of what could be a new-to-the-UK design. If rational procurement makes rare appearance, even a Thameslink run-on order will not be like-for-like, not least because of the fitment of Automatic Train operation. Given the choice between six months and a year to get a new train accepted, most Programme Directors would jump at the extra time.
Remember how with the Class 91 there was an initial batch of 10 locomotives, followed by a pause for development running followed by the rest of the fleet? More recently, with the Hitachi Class 395 Electric Multiple Units, the first set arrived in August 2007 just 26 months after contract signature (hold onto that number). Seven months later the pre-series batch of four units was undergoing development and acceptance running.
But not until May 2009 did hand-over of the remaining 25 series production units start, with all 29 in service for the December 2009 timetable. And this leisurely development period was rewarded by initial reliability which put me in my place.
Schedule
To get my head round Crossrail’s statement I took the time to create a notional time-line from contract signature in 2014 to the start of the full service between Shenfield/Abbey Wood in the east to Maidenhead/Heathrow Airport in the west in December 2019. Don’t forget that since the Crossrail fleet procurement began, completion of the project had slipped back a year under the Comprehensive Spending Review settlement Crossrail has also introduced a revised service introduction schedule linked to its new signalling strategy (RBI 389 p1).
Services on the core Paddington (Crossrail)-Abbey Wood route will start December 1918. Under the previous opening schedule, this would have been two years after test running was due to start between
It is during this time, according to Crossrail, ‘much of the fleet would have been stored waiting for the tunnels to be completed’. So what did my schedule show?

Commercial operation is due to start in May 2017, with the new trains being infiltrated into the existing passenger service on the Liverpool Street-Shenfield route. Before that there will have to be the usual development and acceptance running. I would reckon that four units would be adequate for this.
So, with procurement deferred there will be a bare nine months to get route acceptance. How fast you then infiltrate onto the Shenfield services obviously involves a number of uncertainties. Siemens’ problems with route acceptance of the Scotrail Class 380 Desiros is a case in point.
But I reckon that a progressive built up of deliveries from one unit a month to two units a month during the testing period could have 14 units ready for service by May 2017. Bearing in mind the concerns over the cost of trains in store I tied inserting a pause in production at this point. But it immediate became apparent that to have the full fleet available by May 2019, you would need to keep on cranking out two 10 car units a month from May 2017.
Deliveries
Two units a month seems to me to be a comfortable output. Commissioning these trains, which are going to be quite complex, will be demanding. So one a fortnight seems about right.
But this does mean that by the time the new trains take over Paddington-Heathrow services in May 2018 you would have delivered 36 units with around 24 in service and a dozen sitting idle. Of course some of these trains would be needed for on-going acceptance testing on other routes, not to mention the not inconsiderable task of developing the Automatic Train Operation signalling system.
So I tried stepping up series production to one unit a week. This would allow a pause in deliveries from June to October 2017, followed by one unit a month up to the start of the Heathrow service and then one a week for the remainder of the contract. But production lines need smooth flows.
Overall, I reckon that the five month delay defers paying for 10 trains a month during the new main production run. But Crossrail doesn’t pay the capital cost but a finance and maintenance charge. So an informed estimate gives around £2 million a month saving for 18 months – which is indeed low ‘tens of millions’, but remember that Crossrail went back a year under the
And, however you juggle production, to have the full fleet available for the Paddington-Abbey Wood/Shenfield service in May 2019, you are inevitably going to have more trains than you need before then. Although experience tells me that when you are working up a new fleet, especially for such a demanding high intensity service, you can’t have too many trains!
Tight
Meanwhile Crossrail has now has a demanding delivery schedule for its new trains. Initially, Crossrail Informed Sources were adamant that the Thameslink specification would not meet their requirement. But recently, this view has been softening.
To my mind, the logical solution has always been a repeat order of the new Thameslink design. This logic is now reinforced by the shorter delivery timescale.
However, that was before the furore over the future of Bombardier. And the above analysis suggests that the real reason for the delay has been to buy time for the Government to try and find some way of getting more work into

In another cloud-cuckoo-land statement to the Select Committee Philip Hammond said that his Department’s ‘analysis’ suggested that Bombardier would be a strong competitor for Crossrail, especially if it took on board lessons from the unsuccessful Thameslink bid. As for Siemens being preferred bidder of the similar Thameslink trains, he did not think that this would put Bombardier at a ‘material disadvantage’, despite there being ‘some commonality between the two fleets.

Political
So, back to Che, ‘oh what a circus, oh what a show’. And what we really need to focus is Crossrail’s statement that deferring the Invitation To Tender would allow the ‘conclusions of the Government’s review of public procurement to be taken into account’.
This can only mean that the contract terms are now potentially subject to political influence if not interference. With Alstom having pulled out, the remaining prequalified bidders will now have to decide whether it is worth risking, typically, £10 million, on preparing a tender.
If there is to be a political deal the shortened timescale makes an established design even more attractive. The most likely stitch up, sorry, commercially attractive option, would seem to be a repeat of Thameslink, with some degree of Bombardier involvement in manufacture and assembly, as has happened in

After analysis of the requirements for the new rolling stock for the Crossrail project, Alstom has decided to withdraw from the competition.

Alstom Statement
++++++++++++++++++++++++++
Once bitten
From the start Alstom Informed Sources were lukewarm about the Crossrail requirement. Remember that Alstom’s innovative bid for the much larger Thameslink order – one of the Company’ ‘must wins’ when it decided to re-enter the UK rolling stock market – failed to make the shortlist.
This bid had been based on a
With its only existing
Then, these costs would have had to be recovered over the relatively small build of 600 vehicles, with no prospect of repeat orders for a unique train in the short to medium term. So, the cold number made it not worth bidding. And the political issue reinforced this.
But as one door closes, another opportunity opens. During the Foster Inquiry into the value for money of IEP, Alstom was promoting a second-generation Pendolino as a credible alternative. Now that the era of DfT buying trains is over (we hope), and procurement is returning to the TOCs and Rolling Stock companies, Pendolino is suddenly back on the agenda.
Alstom want to build it, a ROSCO wants to fund it, and, as Tony Miles reports, East Coast sees it as a potential IC225 replacement. And even more interesting, in independent conversations, the price per vehicle which Alstom is offering and the price at which a ROSCO would be prepared to buy, differ by only £100,000.
Meanwhile, it’s hail and farewell. Paul Robinson, who has done a lot to restore Alstom’s credibility in the

Since its inception in 1983, this column has depended for its continuation on one principle: Informed Sources are never identified, or identifiable.
Put crudely, I have never dropped anyone in it. Put deviously, it is now accepted that I don’t speak to anyone and nobody speaks to me. I just sit in my cell like a Trappist monk writing this column.
But in recent months, talking to Virgin Informed Sources, they have been obsessed by not appearing to say anything which might be interpreted by the Department of Transport as supporting the company’s bit to retain the Intercity West Coast franchise. There is a standard clause in the franchise Invitation to Tender which bans such publicity on pain of exclusion.
When the bidding for the replacement ICWC franchise was deferred, the pressure was even greater as Virgin began negotiations on terms to extend the existing franchise from 31 March to December 2012. These negotiations are still on-going, with DfT waving the big stick of Directly Operated Railways taking over if Virgin won’t come up with a sensible offer.
32 fouettées
So, all very tense, until on 17 August I received an email from the Virgin Trains Press Office with a copy of the West Coast Trains Report & Accounts for the 2010- 2011 financial year attached. This was not so much a volt face as the full 32 fouettés en tournant from Act 3 of Swan Lake.
It was the first time since Virgin won the ICWC franchise in 1996, that that the Company had promoted the Report & Accounts to the press. Previously the accounts had been deposited, as required by law, with Companies House, from where those with the time and access could disinter them.
Clearly Virgin Rail Group (VRG) now sees its recent commercial performance as boosting the company’s credentials in the bidding for the replacement franchise. Perhaps the change in policy is related to the warning Transport Secretary Phillip Hammond dished out at my chum Nigel Harris’ National Rail Conference.
Reportedly Mr Hammond told the transport groups present ‘If you have spent the last ten years screwing us, then don’t spend too long filling out the pre-qualification form’. And it is no secret that DfT civil servants still think they were screwed by the deal struck with Virgin to reinstate the West Coast Franchise.
Recap
At which point a brief bit of history for new readers.
By 2002, Virgin’s West Coast and Cross Country franchises were struggling financially – in part due to problems with the West Coast Route Modernisation.
At that time the Strategic Rail Authority (
In the event, it proved impossible to agree terms for the re-instatement of the Cross Country, franchise, which was re-let. But under what is known as the Amended and Restated Franchise Agreement (ARFA), West Coast was reinstated on
Under Cap & collar, DfT was entitled to a share in the franchise’s income above the revenue line in the franchise agreement from the start. And, after two years, the franchise became available for support from DfT if income fell short. At that time, the ‘collar’ was generally not available to a new franchise until after four years had passed.
Virgin knew it had got a good deal. But you can strike a favourable deal only if the person on the other side of the table lets you get away with it. And when DfT realised what it had signed up to it thought that it had been screwed.
Unscrewed
Which brings us to Virgin’s fanfare of trumpets. This might have been seen as rubbing it in. But what if it turned out that DfT had got a good deal after all?
And wouldn’t it help restore DfT’s amour propre if it could show that the franchise was making shed-loads of money for the taxpayer? Hence, I suspect the high profile announcement. Win-win as they say.
And it is a good story. The headline figure being a net payment to Government, under Cap & collar, of £110 million in the 12 months to
falling subsidy profile plus revenue growing in step with ridership at 11% a year, the payment is likely to be over £130 million in the current, final, year of the franchise.
Growth
Ridership and revenue growth, despite the current economic conditions, is attributed to increasingly strong weekend travel and marketing campaigns. And yields have improved. ‘Look’, VRG is saying, ‘when it comes to running franchises for the benefit of the taxpayer, we are the experts’.
All very public spirited, of course. But the joint owners of VRG, Virgin (51%) and Stagecoach (49%), are not altruists. The accounts show that they received dividends totalling £30.5 million in 2010-2011. A further £10 million has been paid out in the current Financial Year. Add in the £67 million dividend paid in 2009-10 and £107.5 million will have gone out of the industry in the last three years of the franchise.
While this will undoubtedly get Union Leader Bob Crowe spluttering into his mug of tea, this column reports things as they are. And that is the way the railway is structured. In the private sector risk is supposed to earn a reward, but not necessarily, as National Express discovered.
West Coast Trains, the company which operates the franchise, will cease to trade when the current franchise is terminated. Should Virgin Rail Group retain the franchise in 2012, a new operating company will be established.

But getting into the detail of the results, brings home not so much the lack of transparency as the sheer opacity in the finances of passenger franchising. Take, for example, the issue of track access charges, also raised last month.

Compensation
In passing, take a look at Table 4. Readers may remember that one of the issues which helped bring down GNER was Railtrack’s better than expected operating performance. As a result GNER received less in compensation that it had assumed in the franchise bid. Note that despite improved performance by Network Rail, West Coast Trains received £2 million, equivalent to 4% of fares income.
Finally Table 5 demonstrates Cap & collar in action.
According to Virgin the ARFA allows for adjustment to franchise payments under a number of circumstances, in particular, revenue share and revenue support.
To recapitulate, up to a 2% variation either side of the revenue forecast in the franchise agreement, the operator takes all the gain or all the pain. Between 2% and 6% the difference is shared equally between the operator and DfT. Above or below 6% DfT either takes 80% of then profit or covers 80% of the loss.
Note in Table 5 that DfT still pays the subsidy and the cap payment is netted off. So while subsidy payments fell from £68.1 to £44.7 over the two years, payment under the Cap & collar regime trebled.
Super profit
On the basis of the gross payment to DfT, a back of the envelope calculation suggests the West Coast Trains’ fares income in 2010-11 was just over £200m above the budget agreed when ARFA was signed in 2006. Can we criticise any party for this?
A prudent VRG would have kept a bit up its sleeve for contingency. A prudent DfT would have gone for a conservative estimate, knowing that Cap & collar would claw back any massive over-performance. And in retrospect, bringing in Cap & collar early was a master stroke rather than, as I saw it at the time, a safety net negotiated by a crafty VRG.
We are so inured to TOCs running into problems when over-optimistic revenue forecast are wiped out by stormy economic times, that we over-look the possibility of top class old-BR management getting it spectacularly right. And don’t forget that these results are despite variable infrastructure reliability hitting Virgin with days when the PPM can fall 20 percentage points below the Joint Performance Improvement Plan (JPIP) target.
So, back to Mr Hammond’s injunction, I reckon that VRG deserve their prequalification. Which leaves the question of just which of the owning groups Mr Hammond was warning? I suspect it was just braggadocio, with no particular target in mind.
Meanwhile, don’t forget that these ‘profits’ are entirely spurious. If you add West Coast Trains’ share of Network Rail £3.8 billion direct grant to the track access charges, this indirect subsidy more than wipes out the additional revenue.

But in the case of IEP and Thameslink there is an alternative. And the key downside – inflexibility - looms larger, especially in the case of the Intercity fleet. The long term ability to move rolling stock around has always been important. A captive fleet tied to captive depots, with likely eye watering charges to move, say, a dozen units to another part of the Network, does not seem a good idea.
Forster
Sir Andrew Foster’s review of the value for money of IEP and its credible alternatives, effortlessly swatted aside by DfT Rail, looked at credible alternatives. And subsequently Transport Minister Theresa (I speak your weight) Villiers has claimed in written answers that IEP has a £200 million advantage in Net Present Value over the conventional high speed EMU, plus loco haulage beyond the wires, alternative.
I couldn’t make the £200 million stand up (Informed Sources May 2011). And some further research confirms my earlier view that it is a candidate for Informed Sources DfT Dodgy Fata Dossier – or should that be Fatuous Factoid File?
Alternatives
So how does the cost of credible alternatives stack up against the IEP
For this proven train, the monthly capital rental and maintenance cost would be £17,000 per vehicle. This assumes that the deal would not include a performance regime.
EMU
For the credible alternative to be credible, you need real prices. So let’s assume that Sir Andrew Fosters favoured conventional EMU alternative is based on the Alstom Class 390 Pendolino. We know the capital cost – around £2.5 million a vehicle. We know the maintenance cost because Alstom Train Care recently signed a new long term contract which comes into effect next year. We know what the capital rental charge will be because leasing companies, like the ROSCOs are routinely borrowing money all the time. And finally, Pendolino already operates under a Train Service Agreement performance regime covering availability, reliability and operating standards.
Add all these ‘knowns’ together and you get a tad over £30,000 per vehicle per month.
IEP
Now for the
But the ‘no train - no pay’ clause is a risk which the funders of the deal will need to insure against, which will increase the cost. And because the customer pays only for diagrams operated, the Performance Regime covers just availability and operating standards.
According to Informed Sources, when the accountants and lawyers have put this little lot together, the answer comes out at around £50,000 per vehicle per month. And that commitment is for 30-35 years.
Think on’t
Of course, we must not forget the key question of whether a Rolling Stock Company, could fund a fleet the size of IC125 replacement or Thameslink. Well Angel funded the Virgin’s Pendolino fleet, which is similar size to the total number of IEP vehicles required to cover IC125 replacement on Greater Western and East Coast.
And, of course, you don’t necessarily need a ‘ROSCO’ to fund new trains. The Voyagers and Super Voyagers were originally funded by a consortium of Halifax and the Bank of Scotland.

Now diesels consider re-powering
<intro>It was worth a trip to Railtex<outro>
Back in the August column I reported on my peregrinations around the Railtex trade show and highlighted the counter-intuitive representation of diesel traction. Counter intuitive because no one expects significant further investment in new Diesel Multiple Units for the
Two of the attractions on show, well, attractive to Captain Deltic at least, were hydro-mechanical transmissions from, in alphabetical order, Voith and ZF. These drives combine a torque converter, to get the train under way, linked to a multi-speed, electronically controlled gearbox.
And in my show report I mentioned that both companies had identified retrofitting existing DMUs as a potential market for these drives. Of course, to justify retrofitting you have to have a business case and the greater efficiency of the mechanical gearboxes provides just that by reducing consumption of increasingly expensive fuel.
Standard
British Rail standardised on Voith’s T211 transmission for its new generation of DMUs in the 1980s. This is a hydrodynamic unit, which means that it uses the kinetic energy in fluid to transmit power.
Such hydrodynamic transmissions have two types of power transmission components, the torque converter and the fluid couplings. They can be very efficient when working at their optimum speed with the fluid coupling engaged, but this depends on the duty cycle.
In the Class 158 DMU, for example, the T211 can spend considerable time in the converter stage where the ‘slip’ between the blades on the impeller, which is driven by the engine, and the turbine which drive the wheels, heats up the fluid, thus wasting energy. Maximum fuel efficiency depends on switching to the fluid coupling as soon as possible.
What a mechanical gearbox does is provide six speeds. This means that the gear-box can take over from the converter at a lower speed. ZF claim fuel savings of up to 20% compared with hydrodynamic drives for its Ecolife Rail electronically controlled gearbox.
Now this is to be put to the test under a joint venture which will see a Class 158 DMU retrofitted with an Ecolife drive early next year. Owner Porterbrook Leasing, operator SWT and supplier ZF Friedrichshafen are to jointly fund the trials.
SWT is looking for a modest 5-10% improvement in fuel economy from the trial. But even on this basis, SWT Engineering Director Christian Roth expects that a as business case can be developed to retrofit his Class 158/9 fleets with the more expensive mechanical transmission.
Rising fuel prices are expected to strengthen the case. After 20 years, the existing Voith transmissions are approaching the end of their overhaul life
ZF is already supplying its Ecomat-Rail 6 speed
transmission plus reversing final drive gearbox for the Class 172 DMU. But don’t expect Voith to let this market go. It, too, has identified the Class 158 plus the Class 165/166 Networker Turbos as potential applications for its similar DIWA Rail mechanical multi speed transmission. A recent study showed payback over 6-8 years.
This column has been banging on about the need to plan for re-powering of ex-BR EMUs as part of Continued Service Operation for several years now. The potential benefits include energy cost savings of 15% or more through regenerative braking. To which can be added reduced maintenance and improved reliability. With DMUs now in the frame too, it can’t be long before this new market takes off.
