in 1852. The B&A bought the line in 1883 and extended to Riverside, rejoining its main line there. The MTA electrified the line when it rebuilt it for light rail use. The conversion of the Highland branch into a light rail line was pioneering in several ways. Amid a backdrop of failing private passenger service in the United States, it was the first time a government entity in that country had assumed full responsibility for losses on a route. It was also the only example of converting an extant commuter rail line to light rail use.

Suburban service

The citizens of Newton were dissatisfied with their service to Boston and since the early 1870s and had pressured both the Boston and Albany and the New York and New England to improve service, without result. Among these proposals was for the NY&NE to sell part of its Woonsocket line to the B&A, which would then build west through Newton Highlands to Riverside, on its main line from Boston to

. This would create a loop or "circuit" between Boston and Riverside. The founding of the Newton Circuit Railroad by a group of Newton citizens in 1882, with the stated goal of completing the circuit by building a line from Brookline to Riverside, prompted the two railroads to take action. In 1883 the New York and New England sold the line between Brookline and Newton Highlands to the B&A for $411,400. The B&A completed the missing and opened the new branch on May 16, 1886. To encourage commuter traffic the B&A offered reduced-fare commutation tickets. The introduction of frequent service to Boston led a population boom in Newton. Three new stations on the extension opened as they were completed:

Trains which traveled from Boston to Riverside via the Highland branch returned via the main line, thus completing the "circuit". In 1904 a round trip took 1 hour and 15 minutes.

was rerouted to join the Highland branch south of Riverside. The branch ran with overhead electrification between Newton Lower Falls and Riverside until 1930, then with locomotives until 1957. By November 1912, the Highland branch had 30 daily round trips, plus several Needham trains operating via Newton Highlands. This frequency dropped by one-quarter by 1919 (with many Highland branch trains not completing the circuit on the main line), then stayed constant for two decades. The B&A upgraded Brookline Junction to centralized traffic control (CTC) in 1932, improving the flow of traffic between the branch and the main line. By 1950, the Highland branch saw just seven daily round trips.

business had ceased to be profitable for most railroads in the United States. Causes included high structural costs of doing business, loss of demand outside of rush hour, and restrictive regulations. The Boston-area railroads were not immune to these trends, and as the decade wore on sought to end or reduce their money-losing commuter operations. In addition, the extension of the Massachusetts Turnpike over part of the B&A main line would reduce its capacity going forward. By 1957, daily ridership was just 3,100 passengers. The

The state legislature approved the purchase and a total expenditure of $9.2 million on June 20, 1957. By the time the New York Central ended the seven inbound and nine outbound daily trains on May 31, 1958, daily patronage on the branch had fallen to 2,200 passengers.

on July 4, 1959. Total construction costs came to $8 million. Daily ridership was 25,000, ten times what the B&A trains had carried at the end. The project was "ahead of schedule and under budget", and ridership exceeded projections. The faster acceleration of the electric streetcars permitted faster operation between downtown and Riverside (35 minutes versus 40 minutes) than the conventional trains they replaced. While other government entities were subsidizing passenger operations around the United States, it was the only example at that time of a government entity taking on the entire cost of what had been a private operation, and the only case of a commuter rail line converted to light rail. By 1960, the line was estimated to reduce rush hour congestion in downtown Boston by seven percent. Though successful, the conversion was cheaply constructed, and further upgrades were soon needed. From June 1960 to January 1961, the MTA enlarged Riverside Yard and added a maintenance facility, upgraded the power infrastructure, and improved the signalling system. In 1967, the

as part of systemwide rebranding. Ridership on the surface section of the D branch has remained relatively constant since 1959 - a 2010-2011 count found 24,632 weekday boardings. Short sections of the Highland branch remained connected at both ends for freight service until the 1970s. The Lower Falls branch between Newton Lower Falls and Riverside was out of service after 1972, leaving just the short section at Riverside Yard; the branch was formally abandoned in 1976.

The grade crossing elimination project of 1905–1907 lowered the line in this area to above the lake's surface level. The B&A installed a drainage system to mitigate the heightened flood risk. At Newton Highlands the New York and New England Railroad diverged at Cook Street Junction for Woonsocket. The Highland branch turned back toward the B&A main line, running northwest through Waban. It rejoined the main line at Riverside Junction, from Boston.
