Wellington Hill station opened in 1852, with a former school building built the previous decade moved to the site for a depot.

[1] A two-story wooden depot was built around 1879; the old station was moved and used as a summer house and an art studio at the Underwood Estate nearby.

[3] To eliminate the busy grade crossing of Concord Avenue, the tracks through Belmont Center were raised in 1907.

A massive two-story California Bungalow station was built from 365 tons of fieldstone quarried from Belmont Hill by a local farmer.

[2][6] The 1908-built station building, which is now owned and occupied by the Belmont Lions Club, was added to the National Register of Historic Places on December 4, 1998.
