Norfolk & Western Experimental M2 #1100 rt side -- 100909

Believe it or not, this 1947-8 Norfolk & Western 4-8-0 Mastodon switcher (!) even after experimental re-shopping didn’t have superheating.

In response to a previous posting, on the UP 9000 series 4-12-2 steamers, Practical Pig asks:

“How much better would they run with roller bearings all around?  I wonder how expensive these were compared to the normal floating bushings on crankpins?  How much were those?  They were just some kind of soft babbitt metal, I think.  Were roller bearings as much as ten times more expensive at the start of it all?”

First of all, here are a couple of pictures SHOWING the basic idea of it all:

Timken Roller Bearing Assembly -- 100209

This image from Wikipedia is of an early Timken roller bearing — note the use of grooved rollers.  Obviously, this isn’t very exciting to look at…or is it?  This tapered bearing race on rollers alone made the mechanical late-modern completely possible, and it is difficult if not impossible to imagine how so many of the gizmoes we take for granted could even have existed without it.  It reduced the inertial resistance of huge static weights and masses to a fraction and made the more efficient transmission of power in vehicles, most of all, economically possible.  Indeed, I would go further and say that only with antigravity (or at least magnetic levitation!) may we even speak of any sort of historical movement era beyond roller bearings. 

Now here is a postmodern descendent from (more…)

Otto Perry Archive, UP 9000 by Bill Navari, 1956, Summit CA, Brooks 1926 -- 092709

Engineman Wook is on a trainman’s holiday from the PRR.  Now he finds himself standing off on the far side of the UP locomotive to “get away from conductors, brakemen and other halfwits so a man can THINK!” and studying the problem:
    
“By God, boys, I believe the little bastards have been and poured Wildroot * all over the rail!”

The engine shown, the first of the 1920s Union Pacific RR 9000 3-cylinder series, had twelve (more…)
