[8] [9] Ocean Pier station was open for several years at Dolphin Avenue 0.3 miles (0.48 km) to the north in the 1880s, likely to compete with a competitor – the Eastern Railroad-backed Boston, Winthrop and Shore Railroad – which operated in 1884 and 1885.

[13] The first part of the Revere Extension opened to Orient Heights in January 1952 and Suffolk Downs in April 1952; the second phase (cut short due to limited funds) opened to Wonderland on January 19, 1954 with intermediate stations at Beachmont and Revere Beach.

[13][1] Unlike its predecessor, this Beachmont station was elevated to eliminate the grade crossing of Winthrop Avenue.

When the MBTA planned the Blue Line Modernization Program in the early 1990s, local residents requested that the station be lowered into an open cut similar to Revere Beach, but this was deemed infeasible.

Blue Line service temporarily ended at Orient Heights and buses served the closed stations during the project.
