Having spent a while in the rail industry, my experiences are an advantage with this subject.
It is sometimes said in reference to the Pitmen Painters that only miners themselves have given an authentic artistic portrayal of their work and daily lives. This I think also applies to the rail industry, certainly during more traditional times. I did join for a while, a well known society for railway art and percepions of the subject by the overwhelmingly non railway membership bore this out.
I worked at six depots in all: Old Oak Common, Aberystwyth, Leeds, Skipton, Machynlleth and Shrewsbury.
