The Times Insider article provides an insiderâs view into the New York City subway signal system, emphasizing its critical role in train operations amid constant movement and track switching. The narrative details a visit to the Hoyt-Schermerhorn subway station control tower, revealing a blend of historical and modern systems. The ancient signal equipment, still manually operated, stands in contrast to typical cinematic portrayals of subway control. This behind-the-scenes look underscores the complexities and challenges faced by transit workers in maintaining this essential infrastructure.
The system, which routes trains and controls and monitors their movements, is essential in a city where trains are constantly switching between tracks at more than 200 crossing points known as interlockings.
Most of the subway system still uses ancient signal technology. The equipment has to be manually operated, around the clock, from a network of underground control towers.
