Get the same train every day. Newport to Gloucester. Usually its a really old train (forget the model). Over the past few weeks, I've complained 3/4 times about the strong smell of fumes in the carriage. Ignored. Yesterday it was even worse. Other passengers complained. Train stopped at Severn Tunnel Junction. They shut down one engine (didnt know it had two) and proceeded on one engine. Which made things very slow. Point being. I'm wondering if this is the same train that for weeks has been exhibiting issues which have been ignored and has finally led to this big problem. Which would be typical of ATW who dont seem to give a monkeys once they've got your money.
