Changing Track Polarity Inside the Locomotive
Failing to properly configure the polarity will result in the locomotive starting in
reverse instead of forward or not receiving the DCS signal. Should this occur, it is
not necessary to swap the wires from the transformer to the track or reverse the
locomotive’s orientation on the track itself. Instead, simply slide the polarity switch
located on the tender as shown below.
(The DCS Polarity Switch should be moved forward when the Red Terminal of the
TIU is connected to the right hand rail and to the rear when the Red Terminal is
connected to the left hand rail.)
