None of the unit's Wessex refurbed are going back, the ones wessex refurbed are 158 747,748,749 and 751 all of which are staying, infact, 749 is in Doncaster being refurbed for FGW▸ as we speak!
So it's the ex TPX units?
We're keeping all the ex
TPE▸ unit's and 158745/746 (blue seats, refurbished by Wales&West, Wessex trains' predecessor), we are also keeping 158747,748,749 and 751 which were ex Virgin units which Wessex inherited in 2003 they were then refurbished by Wessex and have pink seats, these set's are staying with FGW and will be refurbished by FGW, they are currently in "Alphaline" livery. the ones which are going back are the 158/8's which are also in Alphaline livery but have blue seats, these sets were refurbished by Wales&West before Wessex trains was "invented".
