Comments on: CP B102 was built by MLW in 1957. It is class SB-10b and weighs in at 230,000 pounds. CP had 4 slugs built new by MLW: B100 and B101 in 1951 and B102 and B103 in 1957. The unit was photographed in Thunder Bay. Location on map is a guess. http://www.railpictures.ca The BEST Canadian photos on the Internet, eh?

Apparently one powered truck didn't deliver enough traction effort. Original assignment for B102-B103 was at Fort William (Thunder Bay) working the hump and switching grain elevators, mated to one of three S2's: 7081-7083. B100-B101 (built with all 4 traction motors) originally assigned the then-new St. Luc yard for hump and yard switching, originally with 7033, 7038 & 7039.

This would indicate that the upgrade was done prior to that date. I have a Motive Power booklet dated February 1, 1972, that indicates the tractor effort being 43,000 for all four booster units.

CP’s Haulage Capacity booklet dated 1962-07-01 showed them still with just two traction motors each, so when were they upgraded to four as shown in the 1976-04-01 booklet?
