This is a strip map of the Santa Monica Air Line that appears on several station platforms along the Expo Line in Los Angeles. As far as I know, this idea is original to the Metro era. As a work of art, the stops are unlabeled, and typical of the PE, it’s unclear what makes some stops “major” or “minor.”

This is actually a lovely little homage from the LA Metro: acknowledging what came before them (the Expo Line utilises much of the Air Line’s original right of way) and giving it due credit. Love it!

Historical note: the Santa Monica Airline was a Pacific Electric streetcar service that ran from downtown LA to Santa Monica from 1909 to 1953.
