36621 Milk Car Transformer Size

That's iffy on the 40w, it should, but it depends on the other draws too.

Your milk car is slower acting than the early ones too.

It also takes easier to move milk cans, without the magnets. This is one item I like to use t-9 teflon dry-lube spray on. Grease can slow it down used heavily, or in the wrong places.

The PowerMax will go into "foldback" mode at 2.5 amps, and won't operate the milk car. Even a small 25-35-40 watt postwar transformer will work better, because they are capable of putting out several amps in a duty cycle consistent with the operation of the milk car without damage or overloading.

Thanks Adriatic and Rob,

There wouldn't be much extra draw except perhaps a couple lights on engine and/or caboose while unloading.

Yes the green light started to flash almost right after pressing the unload button on the controller.

I will test out my 1010 transformer on it to see how that goes.  If OK I may just pickup a small PW transformer for that.  I think the Fastrack operating track can be wired for a dedicated power supply (not track powered)?
