Signals at West Chicago, IL C&NW Railroad Signals at West Chicago, Illinois. From Wikipedia: North American railroad signals generally fall into the category of multi-headed electrically lit units displaying Speed based or weak route signaling.[1] Signals may be of the searchlight, colour light, position light or colour position light type each displaying a variety of aspects which inform the locomotive engineer of track conditions so that he/she may keep their train under control and able to stop short of any obstruction or dangerous condition. There is no national standard or system for railroad signaling in North America. Individual railroad corporations are free to devise their own signaling systems as long as they uphold some basic regulated safety requirements. Due to the wave of mergers that have occurred since the 1960s it is not uncommon to see a single railroad operating many different types of signaling inherited from predecessor railroads. These can be simple differences of hardware to completely different rules and aspects. While there has been some recent standardization within railroads in terms of hardware and rules, diversity remains the norm.

SCL Sulphur Springs Station with the Pinellas County mainline in the view where it enters the traffic control block signal system in Tampa, Florida, 1974. This station and all tracks on this route were formerly operated by the SAL prior to the 1967 SCL merger. The SAL route provided Saint Petersburg, Largo & Clearwater and other locations within Pinellas County with direct rail line service to Tampa. At this time Amtrak was still using this line for Champion and Floridian service in Pinellas county. The GE U-18B # 358, diesel electric locomotive, to the left is sitting on one of two branch line tracks that head to the North. There is an old SAL work train box car sitting on a siding to the right that may be heading to a local historical group. Beyond the station building are two block signals for the mainline and the branch line. This is where the traffic control signal system starts in Tampa. forex exchange market forex pip value euro forex chart day trading picks central bank forex commodity trading system day trader trades |
