Has anyone operated 3rd rail locomotives with Atlas, MTH or Lionel? Has anyone run 3rd rail in a consist with other manufacturers? MTH tethers might be a problem, though.
I realize this is a diesel topic, but here is my experience with 3rd Rail steam.
Most of my 3rd Rail engines, all steam, have been upgraded with ERR so my experience may differ from others. Basically, my 3rd Rail engines run at very different speeds from Lionel Legacy/TMCC engines for the same speed step. I have not even been able to run different types of 3rd Rail engines together.
I have not tried running any Legacy or TMCC engine with a DCS PS2/3 engine. Not even sure it would work. Not sure what the tethers between MTH engines has to do with double heading/MU consist.
My only Atlas steamer is its switcher, which I have not tried double heading with anything. My two Atlas diesels are AA and AB consists
Diesels may be easier to MU different manufacturers.
