I wonder how easy it would have been to hire in a 66 from Westbury to PZ to assist the 57? At least sleeper passengers would have been able to stay put and the resulting
HST▸ cancellations wouldn't have been necessary.
As far as I can see there are 6 options for the future of the sleeper (In no particular order or desirability):
1. Sort out the 57's
2. Use 67's
3 Use 68's
4. Rewire the sleeper and use HST power cars
5. Introduce later/earlier services to/from London and the Southwest and scrap the sleeper altogether. If you alienate enough sleeper passengers with HST substitutes and delays etc then this option becomes easier to implement.
6. Something else e.g other Diesels
Sunday night's failure could have a silver lining as a lot of people use the up sleeper on sunday night to get back to work in London (including
MP▸ 's). Once 'important people' start getting affected then questions might start getting asked.
(I know, I know everyones' important!)
Ironically, quite recently the PM was at Longrock depot talking about the planned refurbishment of the sleeper stock and a proposed 'new depot'. Unfortunately however refurbished stock is not much good if it's sat in a siding while pax are on an HST.
I remember sleeper failures occasionally happening years ago but there were more locos around to rescue it (some good runs behind a 50 or a pair of them) and HST substitutions were unheard of.
