Greetings, I am new to the forum but have been a long time fan of the B&A. Would any one know of a track chart that would show the signals,sidings etc for the B&A or the MM&A lines in Maine? I got a booklet of the yards diagrams from Melvin Photos but have been unable to find anything else. Would appreciate any help on this . Also just watched the Bangor and Aroostook first 100 years on you tube. Great film.
