Wigwags in Southern California – Part 1

A Wigwag is an older form of railroad grade crossing protection. It was also known as a Magnetic Flagman. Think of it as a mechanical version of a person waving a railroad lantern to help “protect” a train crossing a roadway. These are now extremely rare to see as they don’t have gates in addition to the flashing lights.

I’ve either found or learned of only a few in Southern California. In the Los Angeles area, there is only one left – on 49th St between Pacific Blvd and Santa Fe Ave in Vernon along the BNSF Railway.

North Burbank UP to close on May 20, 2014

After serving the traveling public faithfully since 1941, the North Burbank Underpass on San Fernando Blvd in Burbank will close permanently on May 20, 2014. It is one of the more significant structures on old US 99 in the San Fernando Valley. Somewhat ironically, the structure will be replaced with a new interchange at Empire Ave. San Fernando Blvd will be rerouted back to its pre-1941 alignment, this time without a grade crossing. So, get out there and take your pictures while you can. Do the same for any other sections of old highway. You never really know how long they will last.

Streetcar tracks in Bankers Hill

While riding home today from downtown San Diego, I passed some construction on 5th Ave between Olive St and Palm St. It seems that the tracks from the #1 San Diego Electric Railway line are still in place. I had thought most of these tracks were long since torn up. Instead, as seen on Park Blvd, the tracks are merely buried under a few inches of asphalt.

Los Angeles And Salt Lake Railroad – Santa Ana River Bridge

In the Jurupa area of Riverside, there is a really neat old railroad bridge. Built in 1904, it was a part of the former San Pedro, Los Angeles, and Salt Lake Railroad, a subsidiary of the Union Pacific Railroad. This bridge is fairly unique in Southern California in that it is a concrete arch design instead of the usual steel truss type. As it is also a single-track bridge, increasing traffic may warrant an additional span.
