Replacing Lionel's Control Box - Option 1
     (free hanging receptacles)

This How-To project is shared so a replacement can be made of Lionel's original controller.
  Option 1, described here, is the recommended solution.

Lionel made the Steam Clean And Wheel Grind Shop in 1992, 1993, 1995 and the Controller is no longer available from Lionel.  When this three part accessory is acquired, the controller may be missing.  DC power is required for operation.  If any of the sections were operated with AC current they may be damaged.  The following Replacement Controller is based on Lionel's Controller.
