Imagine that: Three trolleys linked into a single train

Looks like Kenmore Square to me. Looking west on Comm. Ave at the current Kenmore bus stop.

Could that be the old girls Latin in back ground

I’d recognize it anywhere. The trolley is where the busway is now.

According to O.R. Cummings this particular group of Center-Entrance cars {6100-6299} were ordered in July 1918. Due to wartime rations on steel and other materials the specs had to be tweaked slightly. Actual construction did not begin until the spring of 1919. Nearly all components were installed and tested at the builder's factory in Cleveland. Once a car was ready it was shipped to Boston. As soon as final prep and tests were wrapped up cars were assigned to carhouses across the system and put into service. The first car of this batch, #6100, entered service on June 6, 1919 at Amory Street Carhouse in Jamaica Plain. #6298 was the final car to be accepted for passenger service on May 14, 1920. It was assigned to Bennett Carhouse, just down the street from Harvard Square.

6231 entered service on October 17, 1919. It was initially assigned to Reservoir Carhouse. Three-car train operation along the Beacon Street Line began on November 1, 1919. Given the trees and everyone's clothes, the above photo must have been taken no earlier than the spring or summer of 1920. Seems when 6231 was not running on the Beacon Street Line it would be used on the Lake Street-Park Street Line. {From the modern B.C. loop along Comm Ave, thence Chestnut Hill Avenue, Cleveland Circle, Beacon, Washington, Brookline Village, Huntington, Copley Square, Boylston Street, and Public Garden Incline into the subway.}

6231 was retired and scrapped in 1947 along with some other cars of its class. The sleek and modern PCC fleet basically made these cars surplus. Only the very heavy ridership of WWII prevented more Center-Entrance cars from being scrapped wholesale during the early 1940's. The final few cars remained in passenger service -- along with a few slightly older Type Fours -- until 1953. A handful were converted to work cars and held out until at least 1960. It is possible a few remained in work service long enough to make the first official MBTA roster in 1964.

Cross the ones who say "Kenmore" with the ones who say "Packards Corner" and you get Braves Field, which used to have a spur off the main trolley line. Perspective is similar to this picture https://thetrolleydodger.files.wordpress.com/2017/09/pict817.jpg
