I mentioned back on February 11 that I shot a few pictures from the Fermor overpass at the south end of CN's Symington Yard. When I was there, a hump power set was pushing an interesting train up the hump.
The train had an assortment of train and track parts in it... loose wheels in gondolas, wheel sets on flatcars, and pieces of pre-fabricated track. It looked like a model railroader's scrap box, on a train.
Note the snow around the tracks, except for the clear switch to the right. Aren't switch heaters great?
As I said, there were loose wheels in gondolas. These would be fun to model.
Also, wheels ON cars.
Here's the tail end of the train going by, and another set of power coming forward. Note the flashing light on the top of CN 7522 indicating remote operation.
