I wouldn't say that the other traction motors remain at "full power". I'd say that the reduction of power to one motor does not automatically cause a reduction in power to the other motors. For example, if a GE AC unit pulling upgrade encounters grease, the wheels on its number one axle will lose adhesion; and whatever power level is going to that traction motor will be reduced in an effort to regain adhesion. When the wheels on number two axle reach the grease, the power to that traction motor will be reduced, but only in the amount that is necessary to compensate for its wheels' loss of adhesion due to whatever grease still remains on the rail. The power reduction to number two axle should be less than the power reduction to number one axle had been because the passage of the first set of wheels will have conditioned the rail to some extent. This progression will continue, axle by axle, with the traction motor on each successive axle needing less of a power reduction than the preceding traction motor had needed. In other words, if you consider the aggregate power reduction for all six motors, there will be less of a reduction with single-axle control than there would have been if each axle had not been independently controlled.
YUR back peddling now, you said no loss of power to the other traction motors, and coming up with crazy stuff like..."less than the power reduction to number one axle had been because the passage of the first set of wheels will have conditioned the rail to some extent." Pure speculation is what all that is, im pretty sure it doesnt work like that, im gonna check it out for you to be sure. You have no idea what its like to stall out, let alone hit a greaser with a heavy train. I do the things you read about, i keep giving you the benefit of doubt. Being a locomotive engineer who see first hand how GE's handle wheel slip, i think your wrong. Like i tell my girlfriend when we argue, stay on topic, dont bounce around from wheel slip, greaser caused wheel slip, AC vs. DC, GE vs. EMD. So what is it you want me check out for you? When one wheel slips does power get reduced to the other traction motors? Im not a walking engine manual, but i do get to see this stuff work first hand. Im gonna watch closely what happens when a wheel slips dude, and let you know how it goes.
Besides your 2nd hand CSX handout, wheres your information coming from dude? What is it you do for work? Not much in your profile there buddy. Kinda like to know your not a Frosty Cream employee.
Good talk going on here.
