The Sierra Madre Line branched north from the
Monrovia–Glendora Line in San Marino and its two tracks ran between the dual roadways of Sierra Madre Boulevard passing Lamanda Park Junction (Colorado Street and Sierra Madre Boulevard) where it met the local East Colorado Street Line. From this point, the line continued on single track in a northerly direction along a private right of way in the center of
Sierra Madre Boulevard to Michillinda Avenue. There the tracks entered into the pavement of city streets and proceeded on Central Avenue (Sierra Madre Boulevard) to Baldwin Avenue in Sierra Madre, where the station was located on the northwest corner at what's now Kersting Park. It then continued north one and one-half blocks via Baldwin Avenue and turned easterly onto another private right of way (between Montecito Avenue and Highland Avenue) to the end of the line of Mountain Trail Avenue, where a small storage yard was located. ==List of major stations==
