When i went to Stratford-upon-Avon i said it would be my last trip on London Midland as they changed to West Midlands Railway and London North Western the next day (the old franchise has been split into two new brands). Today i finally got to travel on a "West Midlands Railway" train - though in reality it was largely the same as a London Midland one just sans logos. I did see the only (so far) re-liveried WMR train though and Birmingham Snow Hill has been thoroughly rebranded.
In the new year more trains will receive the new purple and orange livery though judging by other train company changeovers (such as FGW to GWR) it will probably be a few years before the old LM green and black livery is gone.
