I was down in Saint John today and saw a few trains...
NBSR 9803 and 2610 were working the east end of Island Yard around 10:00.
CN 8831, 8845, and 8018 were parked by the shops, as was NBSR 3703 with capped stacks. Caboose NBSR 79635 and SW1200 3702 were parked nearby. NB Southern's spreader was also parked in the yard.
On the other end of Island Yard, CN 7060 and NBSR 2612 were assembling a train.
Around 12:30, CN 7060 and NBSR 2612 were at Irving Paper. CN 7010 was working the west end of Island Yard.
I found CN 8018, 8845, and 8831 (as CN 405) at the Courtenay Bay potash terminal with a string of 39 empty potash cars. They called the NBSR yardmaster, and after some banter they rolled out at 12:58 to return to Island Yard.
A little later, NBSR 2610 and 9803 were at the east end of NB Southern's Dever Road yard while NBSR 2318 was working the west end. That was it for my day in Saint John.
By process of elimination, NBSR 9801, 9802, and 2317 are probably still the road power. I assume 2319 is in the shop.
Please forgive the cruddy photos. My Canon S3 is on the fritz (another post) so I had to use the 1 megapixel still camera in the Sony video camera.
