Lionel 8150-55 GG1 Pilot Truck - In 1977 Lionel/MPC began to reissue a number of the postwar locomotives, one of which was the GG1. This particular GG1 was decorated in the typical Brunswick green with 5 stripes. Others included the black Penn Central. The pilot trucks used were a modified version of the postwar pilot truck. The modification eliminated the coil type coupler in favor of the later magnetic type coupler. Other than this change, the pilot truck is identical to the postwar version. This truck is used on all versions of the GG1 produced from 1977 through the early 1990's. The 8150-55 pilot truck is the same as the later 8753-55 pilot truck.
