This is the train maintenance and repair area for the layout. Featured prominently in the photo is a postwar Lionel Number 5F Test Set. This test set was first made available to Lionel Authorized Service Stations in January 1962. There are Super O and HO test tracks on top of the test set. The test set has a built in AC transformer to check three-rail trains and a DC power pack for two-rail HO trains. The original instruction book and test leads are also seen in the picture.
