I could suggest tri-mode stock for Manchester-Bournemouth - but will steer clear of that for the moment! The very idea of suitably modified Class 373 power cars at either end of 7 Mk 5 trailer cars would be really daft.
Well yes, it would be really daft. Slightly less daft if the electric spine had gone ahead would have been taking a bunch of coaches out of some 373s to make them about the length of an IC125 (2+8 or 2+9 formation) for Manchester-Bournemouth, but the current requirement for diesel south of Birmingham kills alot of ideas.
We obviously know that Hitachi, CAF & Stadler can produce new Bi-Mode trains with a minimum of 110mph, can any of the others compete and have capacity to produce a product at short notice without a 3 year lead time when the franchise is re-let in late 2019, early 2020? Bombardier, Siemens & Alstrom what do they have available, do they have many large orders, could they fit in a fairly small XC order in?
CAF? Have they offered a bi-mode for the UK? I understood that it was Bombardier, Hitachi and Stadler offering bi-modes for the Midland Main Line (MML).
Water under the bridge now, but I do sometimes wonder whether XC would have been better as a 100mph railway - too late now I appreciate but IMHO the benefits of brief sections of 125mph running are outweighed by the price that you pay for that (the "crumple zones" that take a chunk out of capacity, the requirement for specialist stock).
The "crumple zones" are why I wonder how similar the class 220s are to 222s... If the entire MML intercity fleet is to be replaced by new bi-modes and all 27 class 222s go to XC could the intermediate class 220 vehicles be inserted into 222s? Most of the leftover class 220 driving vehicles would then be scrapped; less "crumple zones" = more passengers carried per unit of diesel burnt.
If you were to disband 27 class 220s in that way (so no change in the number of units at XC) you could reform the class 222s into 8x 8-car sets and 19x 7-car sets. Refurbish the lot while you're at it, putting a (small) toilet in the former shop from the XC sets and ensuring seats line up with the windows and the seat pitch is reasonable and you might actually end up with some reasonable intercity trains. That'd be phase 1 of my proposal for XC's intercity network. For phase 2, complete GW electrification to Cardiff, Bristol (both routes) and Oxford. I'm assuming that Paddington-Cardiff/Bristol/Oxford would provide sufficient work for GWR to have a fleet of 14 straight EMUs. To provide these, procure 98 new class 80x MS/TSO vehicles from Hitachi; no driving vehicles (we don't want anymore "crumple zones" and GWR also have rather a lot due to all those 5-car sets) and no new diesel engines.
What you do then is take 28 of GWR's 5-car class 800s, remove the three intermediate (MeS) vehicles with diesel engines from half of them and stick them in the other 14 effected GWR 800s. Result: 14x 8-car class 800s with six diesel engines, a reasonable power to weight ratio. The other 14x class 800s (now reduced to useless 2-car sets) would then have the new MS/TSO vehicles added to make them into 9-car class 803 units (not 801, as they wouldn't have a diesel engine for limp-home mode; fit batteries instead) for the GWR electrified routes.
GWR would then be left with:
- 22x 5-car class 802 bi-mode
- 21x 9-car class 800 bi-mode
- 14x 9-car class 802 bi-mode
- 14x 9-car class 803 EMU
- 8x 5-car class 800 bi-mode
- Total 79 units (compared to 93 today, a loss of 14 units but with the capacity doubled on 14 of the remaining units)
And XC would have the following intercity fleet:
- 5x 2+7 IC125
- 14x 8-car class 800
- 8x 8-car class 222
- 19x 7-car class 222
- 20x 5-car class 221
- 4x 4-car class 221
- 7x 4-car class 220
