I have a Lionel 6-18311 Disney EP-5. It's a single motor unit with an electronic E-unit. I'm thinking of adding a second motor. Maybe TMCC and sound. Can I replace the dummy truck with a motor truck ? Does any know the replacement truck part number ? If I add a second motor will the existing E-unit handle it ?
Or is ERR Cruise Commander best with the Railsounds EP-5 kit ?
Or is there a TMCC EP-5 that I can purchase used where I can just exchange the shell with no modification ?
