The old yard was removed when the red line was extended north of harvard, in the 1970's some time I think. A hotel and park was built on the old yard/barn. Streetcars and trolley buses were also stored at Bennett yard. It was located up against Memorial drive and extended over to the current Bennett alley where the T buses pull through by Mt. Auburn Street.
Replace the 57 with the Green Line!!! The people demand more transit, more new routes
