LOS ANGELES — Metrolink has rolled out the use of smart crossing technology — which avoids unnecessary delays at grade crossings near stations — with its introduction at two crossings near its Baldwin Park station.
The Wireless Crossing Nearside Station Stop technology communicates with positive train control to prevent crossing gates from lowering as a train approaches or is stopped at a station prior to the crossing, activating them only as a train prepares to depart. The system has been installed at the Pacific Avenue crossing to the west of the Baldwin Park station and the Ramona Boulevard crossing to the east.
“Our investment in ‘smart’ technologies demonstrates how Metrolink is leveraging innovation to shape the future of rail travel in Southern California,” Metrolink Board Director Tim Sandoval, mayor of the city of Pomona, said in a press release. “WCNSS is producing measurable wins for customers and community members, and the results are drawing national attention.”
The technology debuted on the 9-mile Arrow line between San Bernardino and Redlands, and made its first appearance on the larger Metrolink system in San Juan Capistrano in 2024 [see “Metrolink introduces ‘smart crossing’ technology …,” Trains.com, June 4, 2024]. The two Baldwin Park crossings are the first in Los Angeles County to receive the technology and the fifth and sixth overall, following installations earlier this year in Fontana, Riverside, and Moorpark.
A total of 52 locations have been identified for use of the WCNSS system, with the next installation planned for Sierra Avenue in Fontana. Installations will continue as Metrolink can obtain funding for the project.

But it is California where drivers license requirements are null and void.
So, now all we need are smart drivers.
