Hey all, I'm studying civil engineering at Northeastern in Boston and I've been reading a lot about the currently disused light rail freight tunnels that the Chicago Tunnel Company built.

I've always noticed these white squares mounted on the inside of the mouths of the tunnels in the red line. I've always assumed they were an aid for the train conductors so they knew when they were pulled up all the way or whatever. Never really gave it much thought, but then I noticed this at Park ...

There's an open portal for what I believe is the northern entrance portal on the Harbor side in what's now the MassPort Boatyard. It's a very treacherous area with many obstacles, and I tried to get permission to access it for years to no avail. If anyone knows a MassPort official who might give a ...

That fence was replaced last year, there is now a heavy duty wrought iron fence which curves outward at the top. I dunno how it is now that the MBTA has implied more preventative measures, but the mezzanine definitely used to be frequently trespassed. The fence usually had a gap in it and the tunnel...

Hey all. I've been researching the development of the subway here in Boston and have been curious about details in the underground tracks and lines between stations. I have friends who know a lot about the subway in NYC and I've been shown that there are lots of highly detailed maps of the lines the...
