Out of curiosity, do you know what dates this service ran? And any place I can go read more about it? (I'm working on a piece about streetcars which ran into the subway, and this would be very helpful!)Which of these stations was never served by "foreign" suburban streetcars (i.e, from non-BERy systems): Park Street, Scollay Square, Sullivan Square, Dudley, Forest Hills, Fields Corner, Ashmont
Park Street was served by Middlesex & Boston cars to Norumbega Park
As a matter of fact, I actually went ahead and ordered it from BSRA, along with Bradley Clarke's Streetcar Lines of the Hub: 1940s. A valuable resource that I really should have a copy of in general.If you don't have a copy of the book, PM me and I can send scans of the relevant pages.
The Auburndale-Lake-st-Subway line, now running via Commonwealth av, will now run on 20-minute time to the Park-st Subway via Beacon st, Massachusetts av and Boylston st, entering the Subway at the Public Garden.
