"Last Train" was written by Stanley Accrington who, in his other life, was the Station Manager at Rochdale in Lancashire. He wrote it after listening to stories from the old railwaymen that he worked with.

If I can give a quick plug to a documentary called "The Lost Days of Steam" which will soon be up on The Music Well site. Chris Harvey Pollington and myself are both interested in railways in one capacity or another and we decided to produce a programme featuring the memories of retired and still working railwaymen giving their thoughts on the state of the railway as they see it. Dave Goulder and Stanley Accrington are two of the people we interviewed along with people that both of us know or were introduced to along the way.
As well as the interviews, the programme features songs written by Dave Goulder, Stanley Accrington, Cyril Tawney, Flanders and Swann and one of our interviewees Paul McKenzie who has written a few songs about his time on the railway.
I'll let you know when it's online.

Cheers
Mark
