Are these compatible?
I have a 6-1145 Polar express legacy Berkshire and i would lile to run the front half year round but not have the polar express tender conected all year so theres a pere marquette tender i saw but i notice the sensors different on it i put pictures up so the model of the tender is 6-11204 it has a big box sensor under it. maybe there is a different one that is compatible that i may have over looked the first two pictures are mine with the round sensor on top the rest are the other tender i found
