Bachmann makes a very high quality E-Z snap rail system. The system comes in two different metals for the track, both of high quality but not equal in cost. Both for aesthetics and management of the rail system it is important to choose one or the other before buying your track. The tack that is laid on the black trackbed is steel and of lower cost than the track laid on gray trackbed which is silver nickel. If this is your first venture into building a railroad it will be less expensive to use the black steel track. If cost is not of major concern then the silver nickel will prove easier to maintain in the long run. It is probably best to not mix the two because the electrical characteristic of Silver/Nickel and Steel are quite different and over time may exhibit corrosion at the rail joiners.
