Hello, my newly aquired Spectrum 4-4-0 (Denver & Rio Grande) has no switch to reverse the polarity behind the boiler front, only a smoke on/off switch.  The train runs the opposite of my Big Hauler all the time.  How do I switch this over so it will run "with" rather than "against" the other engines?   Mike in TX

Check the following places:  in the cab on floor, or backhead of the fire box, under the cab, or in the tender (remove the coal/wood load).  Bachmann and other manufacturers have hidden switches in many different places.  Since it is a Spectrum engine I would be surprised if there isn't a switch somewhere.

Thomas and Percy in the sets, run opposite to the Large Scale (LGB) convention.  They are set for the NMRA standard.  Percy bought separately has a polarity switch and so does James.

I have changed the polarity on a few 4-4-0s and it is done simply by opening up the bottom and switching the wires from the pickups from one side to the other.
