Just bought an MTH Pennsy decapod (30-1176-1). I’m planning on replacing the battery with a BCR, and I’d like to order the battery now so that when the engine arrives I can replace the battery and run it right away, but I don’t know which battery I need... is there a way to tell from the part number or am I going to have to wait until the engine arrives and open it up to see which one it takes?
Thanks!
