I was wondering that. It’s all very well the day after the merger saying that the same services run and you could say whether a particular service was previously one or the other, but 13 years on none of the services may be traced back in the same way.Both the ex FGW and ex FGWL services have the same stopping pattern up the Cotswold line.
Anyway, since the line was redoubled a few years ago, the timetable was completely rewritten.
