Caption: North portal of a short tunnel at mile 125.6 on the BC Rail Squamish sub as we exit north bound. There was a 15 mph speed restriction here account track curvature and severe terrain. Immediately after exiting the tunnel we were onto a "dry slide" and track with a 10 mph permanent slow order "until track seen to be clear", perched on a rock ledge on the shore of Anderson Lake. Beautiful scenery but treacherous terrain for a railroad.
