I got 6 Con-Cor daylight cars and my dad can't find the right kind of coupler that matches the Bachmann Railfan HO 4449
the passenger cars had long couplers but my dad wants medium length couplers.

I've had that problem for about 4 or 5 months

I have a bachmann ho railfan sp 4449 and one of the dcc decoder wires that connect from tender to engine is broken
