A word of warning B) !
Research takes time and dedication, it cannot be rushed. As an example, the research that I did to prepare an article for The Industrial Railway Record of the railway sidings where I worked took nearly 5 years,(1980/85) and I was on site with access to the works internal archives!
Even so, my final draft was edited and added to by the IR people with information that I had not found. (IR Record 1990 #122).
All my photos, plans etc were passed on to a colleague who later wrote a history of the works itself (Blackheart , Bob Read, Breedon Books 2005 ) and I am told that the reference material we used is now in Derby Local Studies Library.
And while you are researching you cannot be modelling !!
