I am thinking about building a G scale railroad in my frontyard. I need some help with doing this. I want something large enough to be interesting, but not something so big that it will cost too much. I was thinking maybe 100 - 150 feet of track? Would that do well with 1 train? I am thinking of running an Aristo-Craft SD45 CSX locomotive. Approximatly how many cars could this pull, and still look good with the amount of track? Is Bachmann G-Scale track good enough outdoors? Anything else I should know? I am new to the outdoor railways but have been collecting and running model trains for about 10 years. Thanks in advance!!
