After reading all the problems with the SPH pack I did some research and then applied it to the locos.According to the locomotive equipment book that I obtained while going thru the conductors course back in the 90's all the locos had a wheel diameter of 40 inches.Most of the wheel diameters that I see in the engine files are 20 inches.Way too small for a loco I feel.I applied this diameter to all the SPH2 locos and all the places where trains were stalling I didn't have a problem at all.Before the change I too experience stalled on grades that were relatively slight.I know that it's a hassle but you may want to consisder changing the wheel diameter to get better traction with the rail.The SD70 and dash 9 had a wheel diameter of 42 inches.This info was obtained from the NS Locomotive Equipment Book from the Locomotive Department Roanoke Va.Claude Debnam NS Piedmont Division Raleigh East
I'm not sure I understand you correctly. The lines that affect the wheel size in MSTS .eng files are WheelRadius ( 20 ). There are two of these lines, one in the wagon section, and one in the engine section. A WheelRadius ( 20 ) would equal a 40 inch diameter wheel, yes? The techdocs indicate that the number is in inches, and in the wagon section, the size is for non-driving wheels, and in the engine section, the number is the radius of the powered wheels.
This is true.What really made me look at this was the fact that there are locos that I have that have the radius set to 42in. Claude Debnam NS Piedmont Division Raleigh East
Well I'm gonna leave it alone.I'll let the physics gurus pull their hair on it.Thanks for all the comments.You learn something new every day.Claude Debnam NS Piedmont Division Raleigh East
