Rich, Hello, my name is Brandon Otterstrom. I am a Signal Technician with BNSF and the C & I is part of my territory. I have extensive knowledge of how the CTC signal system of the very section of railroad you are modeling was set-up and worked, and I would be glad to help you understand. To answer a couple of your questions: the Steward to Flag Center section was CTC'ed in 1929 exclusively with searchlight signals. Signals were controlled from a machine at Rochelle via direct-wire. West of Flag Center to Savanna Tower was CTC'ed in 1946 and/or 1947 using searchlight signals at controlled-points and color-light signals at the intermediate signal locations. Control of this section was via the machine at the Aurora depot with controls/indications being delivered/received by a DC time-code system. I have attached a file containing three articles covering the CTC system for the C & I and one article describing the two-wire reversible system that was subsequently used in the Flag-Savanna section. Also attached is a signal line diagram covering Aurora to Savanna. I hope this helps. Brandon _._,_._,_ Groups.io Links: You receive all messages sent to this group.
