I have a pretty large collection of Ho scale model trains, cars, track, buildings, etc. It used to cover a ping-pong table with inner and outer loops with plenty to spare when it was set up.
Includes electric speed controller. Worked great. There is also an older controller, though I'm not sure if that one works or not it is included if wanted, probably 70 years old.
Lots of track. About 8-10 x 36" sections, shorter straight sections, curved tracks, switches, etc.
Lots of passenger and freight cars. 4 engines, one steam engine, one Pennsylvania Express (several passenger cars to match), one larger freight engine and one smaller. There are also lots of buildings and other accessories (the matchbox cars/trucks are gone).
Engines are the main value, probably $200 on eBay for them alone so price is firm.
