The 'classic' return-loop wiring ...

... with Power-Pack & D.P.D.T. ( Double-Pole Double-Throw ) switch.





The theory is ...  :old dude:

... The train runs into the 'insulated' return-loop section ...

... & whilst the train is still running ...

... you throw the D.P.D.T. switch ... ( 2-poles + & - ... 2-throw Polarity A & B )

... & the train runs out of the return-loop, onto NOW reversed/correct Polarity rails.



Clear as MUD ... right ?  L:
