Originating from the
6th and Main Street station in
Downtown Los Angeles, the San Bernardino Line exited to the east via an
elevated structure over downtown streets to reach
San Pedro Street at grade. The
dual-tracks,
running in the pavement of the city streets, proceeded north on San Pedro Street, east on Aliso Street (past its connection to
Union Station) to cross the
Los Angeles River and Mission Road on the Aliso Street Viaduct. Directly east of Mission Road the tracks entered a private
right of way which ran easterly and then northerly under the Brooklyn Avenue (Macy Street) Bridge. Paralleling Ramona Boulevard (since obliterated by construction of the
Interstate 10 Freeway), the line continued northerly, past the Macy Carhouse, to Enchandia Junction, where the
South Pasadena Line branched north. From the junction, the tracks headed easterly, still paralleling Ramona Boulevard on the right, through the State Street Yard to Valley Junction, where the
Pasadena Short Line and
Monrovia–Glendora Lines also branched to the north. From Valley Junction (Soto Street and Interstate 10 Freeway), the dual tracks on private way continued east along
Ramona Boulevard, through
City Terrace,
Monterey Park,
Alhambra,
San Gabriel, and
Rosemead to Baldwin Avenue in
El Monte. From that point, the line proceeded east on private way to cross the
Rio Hondo on a
single track steel girder bridge. The line then returned to dual tracks and continued east, still on private way paralleling Ramona Boulevard, crossing
Valley Boulevard and Peck Road to reach the east city limits of El Monte at the
San Gabriel River. Again, the line reduced to single track to cross the river on a long wood-pile bridge before returning to dual tracks on the east bank. From the San Gabriel River, the line continued east, on private way paralleling Ramona Boulevard, to Badillo Street in
Baldwin Park. Continuing, the double tracks ran along Badillo Street as far as Grand Avenue in
Covina. At Grand Avenue, the line became single track and ran on private way along the north side of Badillo Street as far as Banna Avenue in Covina. Here, the line turned in a northeasterly direction and ran on private way (intermittently paved by Ruddock Street, Badillo Street and Stratford Lane ). At Stratford Lane and Lone Hill Avenue (San Dimas Junction) the main line turned and proceeded east toward
Pomona while a
branch line continued on private way northeasterly into
San Dimas on a single track. The main line continued on private way east from Lone Hill passing streets such as Cataract Avenue and Walnut Avenue and, turning gently southeast by Puddingstone Channel, proceeded parallel to Orange Street as far as E Street in Pomona. At E Street, a Pomona local branch line branched south and continued on private way. This diversion from the nearly continuous straight track to the east and west was the result of ranchers and farmers in Alta Vista donating right of way and funding to build the track further north. The San Bernardino Line continued east, on single track on private way, paralleling the
Santa Fe Railway north of Arrow Highway, and passing Towne Avenue and Indian Hill Boulevard in Claremont. Then turning northeasterly the line proceeded to Benson Avenue in Upland where it turned east again to run between Arrow Highway and 9th street. At 13th Avenue, a northeasterly course took the line to Alta Lorna, along private way, as far as Grande street and Archibald Avenue. Proceeding east from Alta Lorna in open country north of Base-line Road, the line passed Etiwanda Avenue and then turned southeasterly at East Etiwanda Creek into Fontana. It turned east again at Citrus Avenue in Fontana and proceeded north of Arrow Route Boulevard, paralleling it through Rialto toward San Bernardino. The line entered San Bernardino in the pavement of Rialto Avenue and proceeded east to a point between "E" and "F" Streets. Here, the San Bernardino Line turned north to follow a private way to its terminus at the joint Pacific Electric and
Southern Pacific station on 3rd Street.
