A fleet of 7-car class 802s would surely be a good idea for the North East – South West services. Using 5 powered vehicles would give an improved power to weight ratio over existing AT-300 formations. Based on current XC fleet usage, that’d require around 20 daily diagrams resulting in a fleet size of around 23 units based on existing AT-300 utilisation figures, which isn’t dissimilar to the size of existing individual commercial class 802 orders.
They could utilise (subject to agreement) established IEP maintenance facilities located strategically along (or close to) the line of route at Edinburgh Craigentinny, Doncaster and Stoke Gifford, and I believe that work is also already being undertaken to allow Plymouth Laira and Penzance Long Rock depots to accommodate GWRs’ class 802 units at the South West end of the route.
That’d be sufficient additional units brought into the franchise to displace Crosscountry’s HSTs (Although Porterbrook might not be impressed to see such short term utilisation of their power door fitted sets, whenever they finally see the light of day), and to permit all the 4-car Voyager units to operate in pairs as 8-car sets on all Manchester – Exeter and the majority of Manchester – Bournemouth diagrams (Or whichever busiest services require them).
Before we go too far down the line of insisting that XC get all 7 coach 80x's there a few things to bear in mind.
Firstly, a 7 coach unit would be stuck being a 7 coach unit, there's no scope to run it paired up with another unit.
More importantly not all 5 coach units are created equal, and certainly not in terms of capacity:
- 220/221 (4 coaches) 200 seats
- 221 (5 coaches) 250 seats
- 802 (GWR) 326
- 802 (TPE) 342
Given the above a GWR 802 has just over 80% of the capacity of a pair of 220's, whilst configure it like a TPE unit and it gets to basically (although a little over) 85% of the capacity.
Even comparing a pair of 5 coach 221's with a GWR 800 gets you to 65% of the capacity (or a 30% increase in capacity on a like for like basis).
As such I would suggest that XC would better, if going for 80x's, with getting something like:
- 10 X 9 coach units (to replace their HST's with a few extra for those services which are already mostly doubled up units)
- 65 X 5 coach units (which is 7 more units than they currently have to allow more units to be run doubled up through the core)
If you counted the core as Reading/Exeter to the South and Manchester/York to the North then that would mean that you'll have a good choice of alternative TOC's services beyond there to mean that shorter units weren't an issue.
With some extra units it could possibly allow service splitting to serve more places. For insance:
- doing a split/join at Basingstoke to serve Salisbury and Bournemouth
- doing a split/join at Exeter to serve Plymouth and Torbay
- doing a split at Crewe to serve Manchester and Liverpool
- doing a split a Sheffield to allow a service to run to Hull
- doing a split at Winchester to serve Southampton and Portsmouth
I'm sure there's others that could happen and there could be issues with those that I have suggested, however it gives you an idea of what may be possible.
Finally HS2 needs to be thought about which will significant alter the demand for some XC services. For instance Birmingham Manchester will be significantly quicker by HS2 and so there could be less demand for those services. If you are mostly running 5/10 coach trains then you can just redeploy units to other services so that they are all 5 coach trains if that's what's needed. Otherwise with 7 coach units you could find that they are under used with little scope to change their usage (at least not without reforming them into 5/9 coach units anyway)
