Does anyone know what is the normal Amtrak engine speed run # is for the F40PH? I read somewhere it normally is set at Run #8 for travel I have the newest MTH Amtrak F40PH and while I believe engine & horn sound is dead on perfect, especially the horn, at run#8 it sounds like the screaming motor will explode. I just can't believe this engine could take more then a few minutes running at that high RPM level...

Apparently you are not familiar with the EMD 16 cylinder, turbocharged 645E3 engine series. Also, since the HEP (Head End Power) generator is mechanically connected to the main diesel, thus in order to provide 60hz, 480 volt three phase electrical power for the attached passenger cars, the main diesel engine MUST operate at a constant 908 RPM, regardless of the load or Engineer's throttle position, in order maintain that 60hz.
