First off, unlike some other reports I have read, all the trains are moving.
I drove down the hill to Walong as always, hooked up, and used my usual technique to head back up the hill.
So in short, while the couplers don't break (which I had managed to not do on my own pre-SP1) if I apply enough power I over heat, and if I don't I stall....

I drove down the hill to Walong as always, hooked up, and used my usual technique to head back up the hill.
- I had to use 1 or 2 extra notches to get moving forward.
- The load gauge stays in the red before it would drop into the green as things got rolling.
- I start getting messages that "Engine #### is in danger of overheating, reduce throttle"
- If I do reduce, I start loosing speed.
- If I don't reduce, one engine after the next will "go offline to cool down", which of course brings me to a halt.
So in short, while the couplers don't break (which I had managed to not do on my own pre-SP1) if I apply enough power I over heat, and if I don't I stall....
