Just wondering if the FA’s and FB’s were good running engines, I purchased a set back in the day when they came out and repainted them to SP Blood Nose paint scheme. I never ran them and sold them to a train friend who was a SP fan, but he never ran them either. He as since passed away and I can get them back from his wife if I want them, so my question is, are they worth getting and what is today’s going price, they have been in storage for 25 years indoors. 2. will there be any problems changing them over to RailPro battery power. 3. will the trucks be easy to remove the electrical pickups, I see they do not have sliders, but have brushes that rub on the wheels. 4. I don’t expect them to be like LGB quality, etc., but what do you think about them in general.
