Southern California regional passenger railroad Metrolink has expanded its smart crossing technology to two grade crossings in Los Angeles County, following testing of the system in four other counties.
On Oct. 13, the wireless crossing nearside station stop (WCNSS) technology became live at two crossings near the Baldwin Park Station. The WCNSS technology communicates in real time with Metrolink's positive train control (PTC) network, activating gates only as needed, Metrolink officials said in a press release.
Previously, the gates at the crossings would activate more than once when westbound trains were just in the area, such as when they were stopped at a station, leading to more traffic congestion, they said.
Metrolink introduced WCNSS technology at a crossing in Orange County's San Juan Capistrano in June 2024. The technology prevented 1,584 unnecessary gate activations and saved 36 hours-worth of traffic delays in the first year of operation, Metrolink officials said. Since then, the technology has been installed in San Bernardino, Riverside and Ventura counties.
WCNSS was developed first for seven rail crossings on the railroad's Arrow service, a 9-mile extension connecting San Bernardino and Redlands. So far, 52 crossings on Metrolink's 545-mile system have been marked for WCNSS upgrades.
