I have a Bachmann overland limited set and recently received a lot of Tyco cars. The Bachmann has ez mate couplers. How do i get the old tyco cars to connect to the Tyco? Also, I have noticed that the controller that comes with the set is, well, crappy, and is only a 1 amp controller. Does anyone know of a good 5-10 amp controller that will hook up easily to the ez track, that is reasonably priced?
