From a bluff near Jacob's Ladder, we watch a Mount Washington Cog Railway Train powering uphill toward the Halfway House at 4,500 ft MSL. This perspective offers not only a not-often-seen view of an ascending train, but of much of the lower half of the railroad as well. In the center of the photo, we can see the hydraulically-actuated switches above Waumbek Tank. Following the line downhill, we can see the parallel passing tracks that lead to the Waumbek Water Tank itself. Just below the tank, the tracks merge at another switching station. Just above the smoke plume is the coaling pit located at Marshfield Station, where all trips originate. Speaking of the smoke plume, that's known by the local tree-huggers as "Cog Smog".
