You've summed up the flawed thinking of the DfT quite well there. *Please

Roger Ford guesses a 200 hp diesel generator will need to be included
under one of the carriages in each unit. It's not a terrible idea but
I can't imagine a cost benefit analysis on it is positive - how often
is the track navigable but the traction supply unavailable?

Plus you['ve got to test the thing to make sure it's functional before the
train goes out each day. Is it a critical failure if it doesn't start
(which will do /wonders/ for train avaiablilty)?

Personally, I rather liked UR's suggestion of a Spearfish power pack
for the emergency self-propelling capability, but each use of a power-pack
wouldn't be cheap
