I know ...That's what I thought but when I just got this FM it had no other antenna in the shell just a wire to to the side metal railings! @4" long then soldered to side rail ( Part # under shell says lionel Mt Clemens Mich 48045 2321-5 )
Also it derailed all the time I ended up uncurling the wires from the electo coupler and made a lot of slack for it to turn both ways the same.. I put postwar FM truck one one end .. I ordered another because on my 031 tube turns the orgianal truck arrangement drags a lot.. I going to forfeit the motion sound for better performance
thanks for the post...Daniel
