However, I'm confused by the claim in post 15 that the 225s aren't suitable for anything other than the ECML.
Well considering their top speed, and the fact they are a long distance Intercity train, then there isnt much they perfectly suit. OK yes you could run them to Norwich or on TPX services, but they arent perfectly suited to this.
So which runs are they really suited for?
ECML
WCML (with tilt bogies added)
MML (once electrified)
GWML (once electrified)
WCML has bendy pendys.
GWML would be good, if IEP was scrapped. They could operate the South Wales and Bristol services, alongside the 125s operating down to Plymouth and Penzance.
MML- Yes, again, could be good
So out of the GWML and the MML, are any better suited than the ECML?
Well the MML has less 125 running, and more frequent stops.
So the only routes perfectly suited to the 225s, are the ECML and possibly the GWML.
Whilst they could do a good job on the MML, whats the point in moving them if they are better suited to their current role? You only move them if they are better elsewhere. Considering they were designed with the ECML in mind, thats going to be unlikely.
