convert 44 tonner to batt power

I’m preparing to convert a USAT GE 44Tonner to battery power using Aristo TE and LI-on batteries in trailing car. I’m thinking about putting in a DPDT switch so it could run either track or Batt.

Has anybody done this? Any helpful hints? I figured I’d ask and save headaches!

This is how Tony does it -
