This is a used G Scale Aristocraft Panhandle & Santa Fe Railroad Passenger Car Set Of 6. Only ran indoors as far as I know Working smoke in each car with switch Working lights in each car witch switch 4passenger cars 1 baggage car 1 combine car Spring type power pickups on wheels 1:24 scale Some of the wheel insulators that separate the wheels are cracked and I would recommend replacing them but they are all working at the moment I have tested 2 of the cars for smoke and they do appear to work but not very well. I cannot confirm if all smoke units are working Due to the power pickups on the wheels, I would recommend that you have an engine powerful enough to pull this train. There is some resistance while pulling.
