Tyco produced the TR-X series for one year only in 1985. The team racing series came with the front car on a HP-7 chassis and the rear car on a dummy HP-7 chassis. The front car pulled the rear car using a connector between the chassis. A concept that didn't work very well and didn't catch on. The track is unique that it has side walls to prevent the pulled car from falling off. These cars will run on regular HO scale track as well. |
