You made a slight goof that I tried to warn against. To illustrate why, let's say you were running at 40 MPH. 18819x40/375 = over 2000 horsepower, which is "a bit high" for ~1880.

You have to figure the tractive effort the locomotive can make at the given speed, which is lower than its starting tractive effort. This depends on boiler capacity, which is why I was asking Jeff about the heating surface of the rebuilt C-19's.
