It was part of the New Haven/Northampton line, established in 1848, which connected Plainville to New Haven. The depot played a role in transportation until the 1920s and was used for deliveries until 1960. In 2014, the depot was transformed into a museum, preserving its historical significance. The museum contains photographs and memorabilia donated by the Southington Historical Society
