I am seeking information on the role of the blacksmith in
railroad shop practice during the steam age.  Specific questions
I have are:  in which union did the blacksmith hold membership,
did railroad blacksmiths generally manufacture or repair items,
how common was forge welding in railroad practice and did the
railroad maintain different types of blacksmith shops?  Any
other information would be appreciated I have just begun
research on a paper to be presented in July.
