Over the past nine months, the MTA New York City Transit has been partnering with two electrical engineering companies to test a new form of signaling technology on the 7 and L subway lines.
On Jan. 23, the agency took over a train at the Woodside 7 Train Station to demonstrate the results of the pilot for Ultra-Wideband Radio (UWB), a complement to the modern signaling installed on the 7 line as part of the MTA’s Fast Forward plan in November 2018.
The updated signaling system on the 7 and L lines is called Communications Based Train Control (CBTC), and it allows more precise control of the trains, so they can run more closely together. The demo pitched Ultra-Wideband Radar, a technology that would enhance the signaling upgrade to provide faster updates and more precise data on train locations that would, in theory, improve train service.
