Here’s another compilation of Factual Facts, this time, it’s about safety first on trains
1. Did you know that, back when the first steam locomotives were built they had no brakes at all. To stop or slow down trains and steam locomotives was to manually apply the handbrakes on each carriages and tender but the only quick way to stop them in a hurry was to “throw it in reverse” by putting the reverser (or Johnson bar for US) in reverse and using steam as a brake. This lasted until 1860 for vacuum brakes for England and 1869 for Westinghouse air brakes for America which were common standard brake systems.
2. Did you know that, link and pin couplings were a dangerously simple couplings that the railway worker hold the link on one hand and lifts the pin and slips the link into the draft box and quickly lock the pin on the link. By 1900s, link and pin couplings were replaced with buck-eye knuckle couplers due to safety measures but link and pin couplings lasted on forestry railways and sugar cane trains.
3. Did you know that, Railway signal block system replaced the time interval system for a safer train operation. Previously, railway time intervals works like this “When a train has left a section of track, in every five minutes or so; a new train will depart.” This was considered unsafe as two trains would follow each other. Railway signal block sections work like this “When the first train passes the first signal box, the first signalman sets the signal at red for the next train to stop, the second train stops at the first signal while first train passes the second signal box. The second signalman communicates to the first signalman that the first train have passed a block section and the first signalman sets the signal to green for the second train.”
4. Did you know that, the terms of Railway Warning Systems, in England it is referred as Automatic Warning System or otherwise known as a “sunflower dial”; in America it is referred as Positive Train Control. But they work the same way to provide safe train operations for both the railway crews and passengers and alerting the crews for signals and speed limits on the railway.
5. Did you know that when Northern Nathan Railway have the safety systems, they have Railway Safety Warning Device (RSWD) and Safe Train Operation (STO). Those are basically Northern Nathan equivalent to British and American railway safety systems.
