Reply to "PRR E44 redux UPDATE FINAL"

PRR ManOGR Forum Member

I went to the club, Cherry Valley, today to run the engine around the club layout and test it's pulling power.

Wowee! I had no idea the engine would perform so well. I had a coal train in the yard, it's regular power units in the shop for upgrades. I attached the E44 to it and I was surprised with its pulling. The club has a 2.8% ruling grade of 30+ feet. Plus a 12' diameter helix of similar grade. It handled them with aplomb.

When I went looking for Pittman can motors, I needed smaller cases. The new motors happen to be 24V. The layout is between 17v-18v. It appears at the reduced voltage the engine is in a higher torque band compared to top voltage in a 12V motor. An aspect that seems to contribute to drawbar pull.
