How about size of drive wheels? Maybe one of the mechanical engineers among us can explain larger wheels VS smaller wheels on the same track. Is there some sort of mechanical advantage for the larger steam drive wheels?

Why is it that two locos -- steam, diesel, electric, whatever, etc. -- with the same weight and same number of drivers have a different drawbar pull? I'm still not sure of what to make of this situation. Did both locos have powered wheels made of the same material? Was only one loco sprung or equalized? Did a sudden wind come up? Rubber traction tires? My mind is going nutz. Cheers...Ed L. [Non-text portions of this message have been removed] ------------------------------------ Yahoo!
