I was up to the model train show in Brewer last weekend and I had the pleasure to chat with with Wayne Duplisea a retired B&A engineer. He said that he liked the F-3's better than the early Geeps and the BL-2's. As far as pulling power went Wayne said the BL-2's were the best. Also I heard that the 502 was in the shop at Derby. Does anyone know if there are any plans to get this engine back into running condition? I'd love to see it on the rails again. The last time I saw it was in 1991 during an excursion run between NMJ and Searsport. I still have my tickets from that trip.
