My friend Lucy (who took the photos) and I were taking a little walk in the snow, and ended up at Alewife Station. Surprisingly, a few of the doors were open, but the station was deserted, there being no T service at the time. When we were on the balcony over the mezzanine, for some reason the departure bell started ringing and we could hear a train leaving! I assume it was non-revenue, but why would they be running a non-revenue train in the first place? Oh, well, the pictures were cool.

The huge building.
The busway was deserted, of course.
The fare machines were still on.
The totally empty mezzanine.
