It is located inside a shopping center on the northeast corner of the intersection of Mission Gorge Road and Cuyamaca Street.

[10] The truncation was originally due to the fact that the path between Gillespie Field and Santee Town Center is single tracked, and having two lines running on that route would cause operational issues.

[10] Until September 2005, Santee city law prohibited rail service after 9:00 p.m., meaning that most evening service terminated at El Cajon.

The law was lifted in September 2005, soon after the Green Line began operation to Santee.

[citation needed] To further reduce operational issues on the single track between Gillespie Field and Santee, the Copper Line began service on September 29, 2024, and the Green Line was also truncated back to El Cajon.
