I built this back around '84 or '85 in a spare room in the mobile home I lived in . Every body thought I was crazy and I guess I was , but it sure was fun and my 9 yr old son loved it ! It was pretty tight in a 14 x 12 room so the whole thing slid back and forth on kind of a rail system made from 2 x 4's . It's four lanes with four 20 volt transformers supplying the power .
And yes , there is a train too !
