Does anyone know when automatic block signalling was installed on the 
C&I? My "bookend" dates are 1917, when ICC valuation maps do not show 
block signals, and a 1925 employee timetable, which states that 
automatic block signalling was in effect from Aurora tower to Savanna. 
Thanks for your help.
