"By connect the sets together   ---  Does your son have in mind running both trains on the same track at the same time and independently control each?  If so,  there is "Cab Control" wiring required or using a DCC system and installing DCC decoders in each locomotive."


I am guessing on the same track or one going one way and the other going the other.  He is new to trains and I am not sure if he understands what he means either.

We are looking at the Bachmann Trains Thoroughbred Ready-to-Run HO Scale Train Sets.  Any information you could provide will be very helpful, as I know nothing about trains.

Can the Ready To Run Sets connect with other Ready To Run Sets?  We are thinking about getting two for our son and he wants them to be able to connect together.
