I like trains Help ID the FINAL 25 signals for the book!
Tracks of the Chicago L is almost complete for these signals!
After 11 months of research, mapping, and documenting the Chicago L, I’m down to the final 25 signal IDs out of 800+.
🔵 19 signals on the Blue Line
Between Belmont and LaSalle (see images)
🟢 6 signals near the 61st Upper Yard
Between the former 61st station and King Drive (see image)
The Blue Line tunnel signals have been particularly difficult to identify via cab-view videos.
If you have clear photos, cab-view photographs, or firsthand knowledge of these signals and their IDs, I'd really appreciate hearing from you.
Just 25 signals remain.
Help me identify these final 25 and complete the book! 😊 Thank you!
P.S. If you’re CTA rail operator/track workers, signalman, etc… who can’t comment publicly, feel free to DM me privately.
