HLCX 6315 is ex-CP 5522, built in 1966. It was recently repainted to dark red. It has a rebuilt engine.
HLCX 8144 is ex-BN 8144, built in July 1980. It looks like it is wearing solid dark blue paint.
What is driving this need for more power? Crude oil shipments from the west, increased lumber traffic, the theories abound. A recent NBSR freight from Saint John had 8000 feet of cars on it, a good sized train for any railway.
PS - sorry for not posting much, I just haven't had time to blog. Hopefully by the end of next week I will have some more free time.
