My Dad is also an enthusiast, and works for Network Rail, Railtrack, Jarvis and BR before that. My great grandad on my mum's side was a Horse handler (if thats the correct term) for the LMS, and I suppose the MR before that. He went on to drive mechanical horses after they got rid of the biological horses. My grandad on my mums side also worked on the railways, sorta, having worked for Express Dairies, washing out the glass lined milk tanks. later on he became a painter and decorator, which qualified him as a painter in York carriage works until it closed. He also lives in York, so frequent NRM visits might be partially to blame. My other grandad, on my dad's side was an engine designer for Yorkshire Engine company, then Hudwell Clarke, and finally Hunslet. Also a lifetime of volunteering at the ALR.
