Central Park kiddie antique car ride

This model is HO scale and is modeled after the one that travels with Wades Show.  I think the trailer only holds three cars but I have included four cars with this model.  I think they have a forth that they use when crowds are heavy.  I have printed this model on my printer and it is good to go as a static model.  The cars are seperate so you can position them where you want them to go.  I am working on a system to use magnets to make the cars move along the track.  The cars have holes in the bottom to accept round magnets.
