Caption: 419 is the nearly daily manifest train north out of Edmonton's Walker Yard to McLannan on the Westlock Sub. This is a former NAR line. Just north of Edmonton, the line crosses the Sturgeon River Valley, a fairly wide, but not too deep hurdle for the RR. The actual crossing is on a reasonably impressive wood trestle. The trains is on the west side of the valley, working up the grade - the top is at Carbondale, proper.
