Connect your PowerHouse Power Supply directly to the track with the TMCC Direct Lockon. Featuring a selectable current setting (for the 135-Watt or 180-Watt PowerHouses), the Direct Lockon eliminates the need for a PowerMaster if you run only TMCC-equipped locomotives. For added safety, the Direct Lockon provides over-current protection and an automatic reset. It is compatible with both Lionel FasTrack and O/O-27 track systems. Includes power wire with FasTrack connectors and one standard Lionel Lockon.
