According to St Theresa, in a written answer.
"Introducing the bi-mode option for the Intercity Express Programme is estimated to save around £200 million (net present value) as compared to introducing a fleet of all-electric trains to be coupled to a diesel locomotive beyond the electrified sections of the railway."
Can it be that her advisors have failed to tell her that the original specification for an ultra-lightweight IEP has turned into a Voyager DEMU clone?
And that a five car EMU ought to have a capital and whole life maintenance cost a darn sight less than the same train with three diesel engines underneath?
Eye suspects that DfT civil servants are even now wondering how to tell their boss that she somehow transposed their NPV and omitted the sentence explaining that:
"Whilst a bi-mode would cost more, it provides valuable insurance against the UK nuclear power programme - and with it electritifcation - being delayed."
Perhaps we will never know. Unless one of Eye's Parliamentary readers feels like asking the question...
UPDATE: This from an Eye reader in the supply chain who wishes to remain anonymous...
Amazing that Villiers can have such an accurate NPV saving for bi-mode against EMU+Diesel when suppliers of modern diesel locos (Builders and Lessors) were not even consulted on relative costs both capital and whole-life.
