This comes up a fair bit on a regular basis. Someone needs to write up
all that is known and get Matt to add it to his excellent site.
Anyway here's what I know. I probably have a 1/2 dozen regulators at
this point of various histories (most used, actually, I sold off all the
new ones I had when first getting started that I got from a store
unloading theirs) I have run 4 train motors all the time. At that level
there is a noticable loading down (top speed is not as fast as with just
1 or two) and any stall can send the controller into overload (like if I
am powering a compressor and the pressure switch is maladjusted).
I ran 6 train motors once on a single regulator. It worked for about 5
min. The regulator got detectably warm, then shut down. I let it sit for
about 1/2 hour and it worked. I never did that again.
Hope that helps.
