Ive spent a decent amount of time waiting in there and haven't noticed any obvious diesel fumes. Then again the real problem is CO2, which of course is odorless so that may still be an issue. Perhaps the tunnel is constructed in such a way that it naturally ventilates?
I agree with you about Back Bay. I actually was thinking about Back Bay when I wrote the post and was going to mention it but didn't as the fumes come from a different source, and a source which it was supposedly designed to accomodate, unlike Harvard. Actually, there was much controversy about Back Bay's air a few years ago and supposedly, work was done to try to alleviate some of the fumes, but I've been in there recently and it still can get quite dense. I will say however, that prior to the work that they did with the ventilation, it was worse. A train would come in and the place was like a house on fire.
The Harvard tunnel intrigues me however as I doubt if it was designed to ventilate much more than what humans produce for carbon dioxide (CO2). The carbon monoxide (CO) coming out of tail pipes is another matter. Somebody must have an idea when buses first got down there. I don't think that I've ever even seen a photo of a bus in the tunnel prior to MBTA.

I thought the stations were on top of each other. I guess BSRA can do a special article on this with 3D diagrams unless you have them? As a fun project, I would love to do a HO scale of Harvard station (architecturally speaking- The HO tracks can be added later), but I really could use blueprints of Harvard station and the adjoining TT/busway area.

He isn't really... Try walking down the ROW with the power on.

I think the latter connection was for the Harvard - Mass station service via Mass. Ave and the Harvard bridge, which ended in the 1949 when the Harvard bridge was rebuilt. (This is from Bradley Clarke's book on Boston streetcars in the 1940's).
