enginEErjon posted:Has anyone asked Scott why the B units on the E6 for 3-rail are unpowered? Seems like lately all B units have been powered (E8, F7, PA) so why go back to unpowered? Is it a cost issue or mechanical issue?
Exactly.... especially for Santa Fe engines. An unpowered B unit is really pointless. (the 3R E8 Bs were unpowered)
Santa Fe had 7 E6's total built in 1940-41. 4 A's and 3 B's. 12LA, 13LA, 14L, and 15LA were purchased and normally ran as an AB set, with #14 purchased as an A unit only. So one powered A unit with a dummy B unit is NOT going to pull a lot of train on a grade especially. Granted the trains they pulled were normally not large trains, 1 powered A unit is just not enough even with traction tires. Make the B units powered. But what do I know!
