I believe the first batch were ordered when it was branded 'LTS Rail' with a green paint scheme. The next batch ordered with the new rebranded blue and pink 'c2c' scheme. I was always a fan of that before the rebrand to show NX ownership.
Exactly that, although I couldn't stand the hideous metallic purple shade NX used for C2C. Seems to have been a common theme for NX, given that they went on to use such a similarly hideous shade over on 'ONE'.
If anyone's interested, the first units where delivered in all over white with green doors and a small green band around the lower skirt of the bodyside. These will have had the all green interior. The mid batch units appear to have had a hybrid mix of green seats, blue / pink interior, the later units finally having an all blue / pink interior. I think that's how it was - correct me if I'm wrong!
I found the seats very comfortable actually a shame that newer trains have harder seating
Standard Chapman seats of the time - as used in anything from 143s, 150s & 158s by Wales & West to 170s and 357s.
Of course the irony I find is that the refurbished /3s were given a Grey/Pink interior by NX which is Oddly very reminiscent of another former NX Franchise, Wessex Trains.
