US-1 Electric Trucking, produced by Tyco Toys from 1981 to 1986, is a line of HO scale slot-car sets focused around trucks. It was similar to previous Tyco HO Scale racing sets; however, the vehicles could be run in reverse due to having guide pins at the front and rear of the chassis. The line was unique because most of the vehicles were able to pick up and deliver loads from various "Action Accessories" without intervention from the operator.
