A previous station, Bath House, was open near the site on the Boston, Revere Beach and Lynn Railroad from approximately 1900 to 1940.

[5] The line ran directly adjacent to the beachfront, a popular summer destination, on the alignment of the modern Revere Beach Boulevard.

The Eastern Railroad opened its Chelsea Beach Branch in 1881 along the modern Blue Line corridor slightly inland.

[6][7] In April 1897, the BRB&L was moved inland onto the modern right-of-way next to the abandoned Chelsea Beach Branch.

[12][13] The Wonderland Blue Line terminus station has been in mostly continuous operation since 1954; however, service has been interrupted several times due to weather and construction.

It was closed for flood damage from February 6 to March 13, 1978, after the Blizzard of 1978, and from June 24 to September 10, 1983, for track work between Wonderland and Orient Heights.

[14] Wonderland was the third Blue Line station to be made accessible (after Suffolk Downs in 1984 and State eastbound in 1987).

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

[22] In 2006, the MBTA settled a lawsuit with the Conservation Law Foundation over emissions from increased auto traffic through downtown Boston due to the Big Dig.

[23] One of these projects was the Wonderland Intermodal Transit Center, included the 1465-space South Parking Garage as well as a new sheltered busway, bicycle storage, and improved pedestrian connections.

[3] The MBTA began work on an elevated plaza at the station and a footbridge over Ocean Avenue to Revere Beach in September 2011.

[27] The $20 million project, including the Christina and John Markey Memorial Pedestrian Bridge opened on July 4, 2013.

[2] The MBTA acquired the Eastern Massachusetts Street Railway bus system, which included a network serving Lynn and other North Shore points, in 1968.

[11] The extension is still continually discussed, but due to the lack of an identified funding source it has not received priority.
