GWR has 143s fitted with Chapman seats as do a couple of 153s. Could the Chapmans from these 153s be swapped with some Richmond's from 156s to match the rest of the 153s and free some Chapman's up?At the moment there aren't enough Chapman seats to allow all the 150s to have them, so I imagine that one will miss out unless they get some more (e.g. by ATW withdrawing their Pacers.)
Also, when FGW refurbished the 158s, those that were retained with Chapman seats were reseated with Richmond's, leaving 158/9s with a mixture of Richmond's and original 158 seats in the same train. What happened to the Chapman's which were stripped out and with the ATW 158s that had Chapman's swapped for Grammars?
