Semaphore on the USS Recruit's Bridge Wing near the southern end of Union Square (south of E. 15th). The Greek Temple in the background is the Union Square Savings Bank built in 1907. It was designed by Henry Bacon who shortly after would design the Lincoln Memorial in DC. The building still stands and is currently the Daryl Roth Theare.

The enscription on the card has a typo - "Widwad" should be "Wigwag" - see: en.wikipedia.org/wiki/Wigwag_(flag_signals)

Unbelievable shot. This guy was good, and man, did he get around!

The locomotive in this picture is number 5000, a 2-10-4 built in 1930 by Baldwin. It is now preserved in Amarillo, Texas. There's more information at the Wikipedia page about this locomotive.

Very interesting information! Thanks for your interest in the collection.

Yes, that's Madame Queen, an experimental 2-10-4 that gave rise to the 5001 class of 1938 and the 5011 class of 1944. The 5011 class were the last steam engines built for the Santa Fe and ran in helper service until 1957 in Abo Canyon, east of Belen. This passing siding is still protected by Automatic Block Signals using upper quadrant semaphores in this photo. Before WWII was over, heavy freight traffic caused this division to get Centralized Traffic Control with searchlight signals.

Hi, I'm an admin for a group called Railroad Semaphore Signals of the World, and we'd love to have this added to the group!
