The "Trains" Locomotive Annual for 2013 has arrived at my local magazine shops.
On page 85, with a small photo of preserved NYC 2500, Kevin P. Keefe reminisces about seeing mail & express train 13 on the Michigan Central in March 1966, with "four U25Bs, shiny in their black-and-white cigar-band NYC paint, rumbling urgently westward with a long line of baggage cars, mail cars, and the requisite rider coach on the end -- doing all of 79mph."
79 mph? By the time the U25B was in production, GE felt that locomotives with 752 motors and the standard 74:18 gear ratio were good for 70 mph (earlier 65 mph seems to have been the standard top speed for units with this ratio), but 79?
Does anyone here know what gear ratio the NYC's U25B had? (If you ALSO know the ratios for NYC and P&LE U28B, NYC U30B and PC U33B, I'd love to know them, too!)
