@Yellowstone Special posted:Well, that is absolutely amazing, John! Your single-motored Mallet certainly IS a stump puller. And that’s an amazing collection of tank cars you have, old and new. I got a kick out of the “vapor” coming from the United States Liquid Oxygen car.
I have a couple of the MTH smoking tank cars, they're a fun addition. I added remote control to them so I can turn off the smoke without chasing the car down.
@Yellowstone Special posted:By the way John, if you MUed 2 Legacy GP9s, I imagine they could do it, couldn’t they? 🤔
They probably would, but I decided to just go for some single locomotive power. 
I had to MU some smaller steam for even fewer cars. The single 0-6-0 couldn't make this grade either, so I broke out it's twin, and got the freight run through.
Interestingly enough, it probably depends on which diesel you use. I have a pair of Legacy U-Boats that pulled 115 cars on Harry's layout, and we have grades there as well. I stuck one in the middle to reduce the strain on the couplers.
