our Lionel locomotive’s tender is equipped with an operating magnetic knuckle coupler, a
revolutionary design first introduced by Lionel in 1945.
Lionel magnetic couplers react to the magnetic field generated by a Lionel Remote-Control
Track section (available separately, 6-65149 or 6-12746 for O-27 gauge; 6-65530 for O gauge;
or 6-12020 and 6-12054 for FasTrack layouts).
Place your tender’s coupler trigger disc over the central coil of a Remote-Control Track
section and press UNCOUPLE on the controller. The magnetic field pulls the disc downward,
and the knuckle opens.
