Hi there,
today I pulled out one of my older MTH ps2 L-3 Mohawks. After about an hour of running, I went to pick up the engine to camp it in the engine shed. I found that it was hotter than CA in mid august. Being all die cast medal I figured it’d be pretty typical from an engine of age. Any thoughts?

That seems abnormal, but then I don't really have a quantitative measurement of hotter than CA in mid August, so I can't be sure. There would likely be a temperature rise of 20-25 degrees Fahrenheit, is that what you feel?
It sounds too hot to me. Most modern engines should only be slightly warm.
I picked up a MTH 0-4-0 at the Springfield show in January. It ran much hotter than any of my other MTH engines after about 15 minutes of use. I was afraid of running it longer for fear of burning something up.
The next time I ran it the rods on the right side came apart completely, causing the left side to lock up. I reassembled the rods, gave it a test run and noticed it ran much cooler (still does). I believe the right side rods were binding, causing the motor to overheat. Check the rods on your engine and be sure it is lubed properly.
One easy test is to measure the current with just this locomotive and consist on the tracks and see if it's using excessive power. Unless you're trying to pull a LOT of cars, you shouldn't be seeing more than about 2 amps with smoke and the load. If you're seeing way more than that, something is amiss.

John, right you are, as usual. I should have mentioned my 0-4-0 was drawing 4 amps before the rod problem was fixed; now it’s 2 amps.

Why the link to this thread, are you into circular conversations?
You got me there
