Not a "good look"? You are kidding right? This isn't some trend on TikTok.
No, it is an industry sustained by many billions of pounds of public money a year.
A broad and positive opinion amongst the population towards the railway is essential for the railway's survival.
In 20 years it will be a choice between a diesel train or an electric vehicle. The railway has built the unparalleled happy time of the last two decades on its apparent environmentalist credentials. Once those are gone it will not be able to justify such largesse to the taxpayer unless it can make itself attractive in that new world. If it cannot it will slip into irrelevance, at which point it will become a go to area for cutbacks by governments looking for money to spend in more popular areas.
The only remotely viable alternative to diesel rail traction is wiring. And that takes time and money.
That simply isn't true, battery electric trains exist, battery electric vehicles exist.
In the UK context, affordable railway electrification no longer exists.
At £4m/stkm, virtually every piece of railway that could justify electrification has already been electrified.
In the 1950s a BEMU was built that had eight tonnes of traction batteries under each vehicle. Today, that would be something approaching 5MWh for a 3-car unit.
That would give a modern EMU a
lot of range, and there are few very long journeys on the UK railway network that have neither any electrification at all or any opportunity for static charging.
Maybe, but firstly plenty of diesel units are no where near end of life and retrofitting them will be infeasible (we’ve tried that and it hasn’t gone well).
Are there that many units that are not near end of life?
The 19x series is the only pure diesel fleet ordered since the 172s in 2010 isn't it?
That totals ~161 units, something on order of 400 ish carriages.
By the end of this decade, every other diesel unit will be 20 years old or more and will be hurtling towards end of life.
And 400 carriages is something like 2.5% of the passenger rolling stock on the railway, which is around 16,000 vehicles.
And more importantly the country and the rail industry can’t afford the cost of replacing all the diesel units and building the charging infrastructure.
Well its either build the units or lose your market share to the electric public transport options that will be around in the 2030s, whether the railway wants to be part of it or not.
Its reasonable that as the technology matures we should have a programme of rolling changes from diesel to battery power, but only where and when its cost justifiable - the setting of arbitrary target dates for such changes merely places unjustifiable and unnecessary economic burdens on the country.
The limiting factor is that the loss of the railways environmental credentials will make it extremely difficult, if not impossible, to justify continuing to pour billions of pounds of subsidies into it when other, greener, transport options are available.
A "rolling programme" that takes 30 years will never complete because the railway will be an irrelevance long before that.
It is far too late for a rolling programme of anything, it is now a crash programme or die.
