Hello everyone...I am new to model railroading, but I'm anxious to get started. I was given an Athearn John Deere Model 'B' Express Authentic HO Scale Train Set for Christmas. It seems to be a pretty good set. The locomotive is an F7A locomotive w/ dual flywheels, operating headlights and 5 pole skewed armature motor. I just found out, through some research, that the set comes with a 14 piece oval of Life-Like Power-Loc track with built in roadbed. My question is, should I purchase more Power-Loc track to go with what I have and expand my set, or go with another style of track without the integrated roadbed? The Power-Loc track is certainly more expensive. Thanks for you thoughts and advice.
