- Santa Fe, to my knowledge, only had one section of cab signals, on the
- Illinois Division between Fort Madison, IA and Pequot, IL. Its installation
- was mandated by the ICC in 1925, and, although the order was rescinded in
- 1928 (just after the installation was completed!) the system lasted into the
- 1970's.
- Santa Fe still maintains long stretches of Automatic Train Stop, however,
- on routes where the Southwest Chief runs 80+ mph. Much of the trackage
- through New Mexico, Colorado, and Kansas is still guarded by the old upper-
- quadrant semafore signals as well, though these are on the way out.
