How viable would a battery powered train be if you had very high rate induction chargers at each stop combined with regen brakes?
don't be seduced by glossy leaflets, they're cheap. Who is proposing it, do they have the money, do they have DfT/PTE/Franchise/ROSCO support?
Even if the proposal is real, how many more years life have the bodies and bogies got left in them?
Has all the old Met, Circle, East London and Ham & City stock already been scrapped?
What sort of % of the old District stock has been scrapped?

They been talking to the DfT about it.

Maybe someone, somewhere, has the idea of running them on the Isle of Wight ?

That sounds like a neat idea.....is there a link to a website for that ?
that assumes you can find someone to build them.
Try finding someone to fund a new build of DMUs for the north? Current prices exceed £2m/vehicle and that assumes you can find someone to build them. Achieving modern emissions standards is really tough. That's why the freight operators have ordered Class 66s for delivery before the end of this year when new 66s can't be built. (Next generation engines don't fit into Class 66 bodyshells.) Few people know that the Cummins NT855R underneath Sprinters is a design from the 1960s! We didn't know what emissions were about when Litchurch Lane built 15n sets throughout the '80s. Now we have to understand these things.
As the 172s are only around 4 years old, I wonder if Bombardier still retain the necessary equipment to build more, if they were required. Presumably the emission rules would be the same as locomotives ?, allowing them to be built before the new rules come into force, construction infrastructure permitting, plus the endless tenders and meetings required of course .........
According to a community rail officer she attended a conference where an option was put forward to create 75 new DMUs for National Rail. The idea is adding complaint diesel engines to refurbished D78 rolling stock released from London Underground in 2016. Does anyone know anymore about this?
Obviously the D78s don't have toilets but then the Pacers and most of the Sprinters don't have toilets which meet the post-2019 requirements of being accessible and retention toilets and also the seating would need to be made suitable for whatever routes they are cascaded to.

D78 door stock width = 1127mm, Class 156 = 780mm. Narrow is relative - Class 158 doors are 835mm, C69/C77 stock 1370mm. With hindsight, the single leaf doors on the D stock were a mistake, cause extended boarding times, and contribute to their earlier than expected retirement.Also, the D78 stock have got 4 doors a side, but they are single leaf and quite narrow (although probably wider than those on a 156 - could anyone give some figures about these)
Wow, D-Stock being converted into Diesel trains? I think I've heard it all now.
I take it the dream plan was to use a Class 55 for motive power and a DVT on the other end, oh and to fit IC70 seats along with putting a Mark 3 dining car in the middle?
Or are they going the full distance and double-heading with 4472 and 4468 on the front and DP1 on the back to round off the photo opportunity?
Almost as crazy as some of the suggestions for what to do with the class 442s.
There should be a dream world and an actual sensible world areas of this forum.
Were you the same one who posted the rumour on one of the local rail users groups sites? They said the idea was being promoted by riva Rail which I presume was misspelt Arriva Rail.

Well, I was thinking taking out the two centre doors and replacing them with full height glass windows.
