Review Of The Article 'Why New York Subway Lines Are Missing Countdown Clocks'
In James Somers article “Why New York Subway Lines Are Missing Countdown Clocks” (2015), Somers looks at the old New York subway system and compares it to the newly efficient and safe subway system called communications-based train control, or CBTC. First, Somers mentions that in the old New York subway system the tracks are separated into sections which display an occupied or vacant track. In contrast, he states that each train supported by the CBTC system is carrying a radio and onboard controller that determines its precise location which is later used to decide how fast it can safely travel. Second, Somers mentions that the CBTC system allows for trains to run in multiple directions. In contrast, he states that the old subway system allows
trains to run only in one direction. Another idea Somers expresses is the construction boom of the 1930s which sparked the establishment of signals, interlocking, and switches. Somers also shows that the train accident on August 28, 1991 due to the old system lead to the introduction of the improved system CBTC. In short, the CBTC system performs more excellent and efficiently than the past New York subway system.
The past New York system and current modern system called communications-based train control (CBTC) both use different parts and processes to meet the public’s concern of train location and safety but the CBTC system surpasses the old system due its increase and advancement of technology. The CBTC approach guarantees the train’s location and safety guarantee using upgraded parts and processes. First, there are transponders installed in the tracks below the train. Next, onboard the train is a radio and computer that provide a location status of the train. After, trackside controllers placed near the train to check the speed of the train. Then, the location and speed status travel wirelessly to the central control center which is coordinates the movement of the train. In short, the CBTC system uses more modern technology to fulfill the public’s wishes of at least having as sense of the train’s location.
