Southern Pacific operated both passenger and freight trains along the route.

In 1912, El Camino Real was paved through San Bruno and Lomita Park.

Originally a two-lane highway, El Camino Real was widened to four lanes in the late 1920s.

Lomita Park had its own Southern Pacific train station and some community services.

The is community still currently identified as the "Lomita Park district" of San Bruno.
