Could you summarise what is better about the class 387 than the class 700 (or what is worse about the 700 if that is easier)?
Edit: I can remember the Conservative publicists trying to sell Margaret Thatcher, from Grantham, as 'a northerner'.
I think 47802 got it, swapping an outer suburban interior for a metro interior.
Yes the seats on a 387 are hard but the space around the seat is much better, the seats are wider and the leg room greater (important when you are just above average in size), also provision of arm rests and tables. Arm rests on longer journeys keep your space a little more private and if you aren't crammed in narrow seats without leg room then the journey is more relaxing.
Tables of course enable work to be undertaken and coffee/food to be rested, again a very useful provision on a 40-50 minute journey.
I think the 387 are a very elegant solution, supplying capacity in a civilised manner and will be a fantastic servant on GWR especially replacing the Turbo's (which we also have at Redhill) and for "Northerners" on GN to Kings Lynn. I and many others will miss them from Thameslink.
The 700's will be functional and get us from A to B, but they will not endear themselves and will make journeys by train a chore rather than a pleasure. I hate it when they turn up (probably explains my grumpy mood today)
