Does anyone know what kind of passenger cars are compatible with the DCC HO Bachmann Spectrum New York Central 4-6-0
#1233  I tried to use an ordinary set of HO Bachmann passenger cars and it won't work.  Could some one lead me to the info.  I have looked up passenger cars that are DCC HO but I am unsure if they will match the Loco I have

I too have a coupler problem.. I have a Bachmann train and engine set ..'The Liberty Bell'  and I have the Bachmann Spectrum New York Central.  I wanted to connect my passenger cars from the 'Liberty Bell' to the Spectrum.  I think I understand what you are saying.  Are you saying that for me to get the passenger cars to run with the Spectrum I must check the space and or length between the two type of sets and see if they match?  Then are you saying that if there is no match do I just unscrew the couplers from the higher cars and replace them with lower couplers from the others?  This won't for me because the Spectrum couplers or wheels are taller I think.  Do you suppose I could find some couplers for DCC trains that would fit my passenger cars?
