    I'll give you just one example. I'll pull a random BNSF ES44AC out of my hat: BNSF 5771.

    The only reason a "pissing match" started was because of your insistence that the gear ratio was the most important factor in determining the performance of a locomotive - to the point that us even...

    These three were all fairly common on road locos 40-50 years ago, but the 65:12 and 60:17 are becoming increasingly rare today. These ones are actually substantially different percentage wise from a...

    The AC4400's are 83:20 gearing. The SD70M-2's are probably 70:17 gearing. SD40-2's are typically 62:15. Those are all less than a 1% difference in gear ratio... Gearing has nothing to do with why the...

    For posterity's sake - I mixed up my high vs. low gear ratio in this statement. Should've said higher gear ratio allows higher top speed. Lower gear ratio gives you better tractive effort at low...

    I am struggling to understand what you're saying. The OP's question is about what causes *predictable* differences in locomotive performance between 3 distinctly different models. If you want to give...

    Hopefully we're not missing the important point here, which is that completely turning off a locomotive is NOT at all equivalent to turning off the generator field switch. Imagine a switching job in...

    I'm sure others will have more suggestions, but one of the best quality Conrail-appropriate routes available for OR would be the Horseshoe Curve route (although it is quite short).

    Gerry,

    I had only ever heard "friction bearings" most of my life. Turns out the actual correct term is plain bearing. "Friction bearings" was supposedly a term coined by the roller bearing...

    I would've figured these ET44AC's had 6 powered axles, and would thus not have the axle weight distribution equipment present on the C4's. Is that not true?
