Very interesting. The railroad signal bridge near the Gilman Street railroad crossing in Berkeley is now retrofitted with newer railroad signal heads. The signal bridge used to have tri-light signal heads (tricolored railroad signals arranged in a triangular pattern), a classic thing from Southern Pacific Railroad. Now they're replaced with modern "Darth Vader" railroad signal heads from Union Pacific Railroad. But the original signal bridge structure still remains.

Interesting history!
