Hello all, Thanks for this site. It is very well informed. Here is my newbie question: I am going to start to build a track layout with my son. Both of us are new to this. I had a cheep track when i was a kid (which i summarily destoyed through immaturity and neglect to the dissapointment of my father). Anyway: We are going to build an Atlas track kit. I think we will do Code 83. My question is: What is the difference in the catalog from the Master Series and the Trainman Series? The Trainman series seems less inexpensive. Why? Is there a difference? Any help would be greatly appreciated. We have not even started to build the table, so we are at square 1 with this. Thanks.
