I am new to building layouts   and I am interested in getting a reversable track set up  My question is  to make the car go back and forth  you need reversable track  right  what about the trolly or car   do they have to be able to be used on that track or it is a special  car I need to buy?  or its the track itself  that reverses the polarity
Thank you
