Hey I'm still in diaper's in this arena. I am taking delivery of the Lionel SF 6-84719 O scale (Santa Fe FT Super Chief) starter set next week that I purchased from ModelTrainstuff.com. I wanted to know your thoughts on a second purchase. I remember riding the GM&O out of Chicago in my youth and saw a Bachman WM FA1 AB diesel set. I'm not familiar with their mechanics, reliability, etc., and wanted to know your thoughts. I'm drawn to the nostalgia behind the GM&O memories. Should I go for it and add the Chicago Western passenger cars, or steer clear? Your thoughts.
