Are you familiar with a moveable point frog as it related to a switch (turnout)? Most switches have a frog that is a single piece of steel with groves for wheel flanges. However, in situations where the turnout needs to support higher speed and/or it needs to support heavier trains, railroads will sometimes install a moveable point frog. Similar to the standard switch point, a moveable point frog requires a second turnout motor and it moves the frog back and forth, create a far smoother (and safer) turnout for heavier trains at higher speeds. This particular moveable point frog is located at CP DS007 (Arvada). When UP added a second main track between C&S Junction and Arvada, the added this turnout for coal trains.

This shot of the climb from Coal Creek Canyon to Tunnel 1 is fantastic because, generally speaking, it is not too hard to find an angle of any train, east or west, at most times of day, and have the lighting be at least decent. Here, a westbound BNSF oil empty is on that very climb, approaching the east end of Tunnel 1.

This eastbound military train was so long, it would not even fit between switches at Rocky! Indeed, the only two sidings between Denver and the Moffat Tunnel that the train would fit on are Rollins and Tolland. The other seven sidings on this side of the divide are all too short. Regardless, the train departs the east end of Rocky, headed for one of the bypass tracks in Denver. There, a relief crew will soon take over, taking the train east on to the KP and across the plains to Fort Riley in Kansas.
