The exposure adjustment makes the interior look a lot less gloomy in the photo than it does in real life. A passageway at right leads to the outbound platform, which has its own sets of stairs and ramps.
Min-high for the inbound platform, with a folding edge for over-width freight clearance. The mini-highs are both on the north side of the Bacon St. overpass.
Winchester Center is barely four tenths of a mile north of Wedgemere, and I suspect the signals seen off in the distance are actually at the entrance to that station.
Back on the inbound side again, with the Laraway Road lot at right, and more temporary shoring to keep the platform from falling down of its own accord
