Driving the 2-8-0 HUD version

I ran a Steam Workshop scenario today that had the 2-8-0 pulling five passenger cars on the Portland Terminal. Before I could reach Rigby Yard, the loco "ran out of steam." I noticed that the steam pressure was 90psi and the coal/water levels were down to about 15%. Are HUD engineers supposed to be shoveling coal and pumping water? I read the manual, but there's not a lot of info on the HUD version.
Please don't take this as negative comments. I love the 2-8-0 but have never been a good steam locomotive engineer. Looking for help, not repairs.
