Los Angeles Metrolink implements PTC

Metrolink, southern California’s regional commuter rail service, has launched positive train control (PTC) in revenue service demonstration (RSD) in cooperation with Burlington Northern Santa Fe (BNSF).

Metrolink, southern California’s regional commuter rail service, has launched positive train control (PTC) in revenue service demonstration (RSD) in cooperation with Burlington Northern Santa Fe (BNSF).

PTC is one of the 5628 National Transportation Safety Board’s (NTSB) top ten most wanted transportation safety improvements.  It involves a GPS-based technology capable of preventing train-to-train collisions, over-speed derailments, unauthorised incursion into work zones and train movement through switches left in the wrong position. PTC monitors and, if necessary, controls train movement in the event of human error. PTC may also bring trains to a safe stop in the event of a natural disaster.

Metrolink now has the ability to implement PTC on specific trains and the Federal Rail Administration (FRA) has authorised its use on BNSF territory using 6079 Wabtec’s  interoperable electronic train management system (I-ETMS). Metrolink’s PTC service on BNSF track will be implemented on select trains on the Metrolink 91 Line. The technology is expected to be available on Metrolink later this year, while the entire service area is anticipated to be complete well before the Rail Safety Improvement Act (RSIA) mandate of December 2015.

The RSIA became law in 2008 after a contractor engineer operating a Metrolink train failed to stop at a red signal just north of the Metrolink Chatsworth Station. This action led to a head-on collision with a freight train resulting in 25 passenger deaths and more than 130 injuries.

The estimated cost for developing, installing and deploying PTC on the Metrolink system including the expansion of the communication network to support the PTC system is US$216.3 million, funded by local, state and federal sources.

Speaking at the launch, Metrolink Board Chair Pat Morris, said: “I have spent my entire life around the rail, but this is unequivocally the most instrumental piece of technology ever implemented for train safety,” said Morris, who worked his way through Stanford Law School at the ATSF Railway. “PTC will undoubtedly make Metrolink the safest commuter rail system in the country; the invaluable partnership between Metrolink and the BNSF has made today a reality.”

“Commuters across the country deserve the safest trains and routes possible, and the adoption of Positive Train Control (PTC) by Metrolink will make Los Angeles one of the first in the nation to adopt this life-saving technology,” said Rep. Adam Schiff (D-Burbank), sponsor of the Rail Collision Prevention Act, which required implementation of Positive Train Control on passenger trains. “With human errors accounting for forty percent of all rail accidents, PTC will save lives and the rest of the country needs to adopt these systems as soon as possible.”

Supplied by Cubic Transportation Systems, ‘the key’ was first trialled in November 2011 on Southern’s Brighton to Seaford line. It was subsequently rolled out across most of their network for journeys outside the Oyster network and those termin

Bus rapid transit (BRT) is gaining an increasingly high profile in the US public transport agenda, for two main reasons. One is the potential for ‘trains on wheels’ to save substantially on installation costs as compared with other modes such as underground metros or light-rail transit. Another, highlighted in the case of New York City, is the value of having a rapid surface-based alternative available whe

    Drivers are an increasingly rare species on Europe’s commuter metros as unattended train operation is embraced. David Crawford takes a low-speed tour of the continent’s capitals to see what’s happening. Unattended train operation (UTO) is fast becoming the norm for Europe’s metros, on existing as well as new lines. November 2017 statistics published by the International Association of Public Transport (UITP) show the continent as having 28% of the global total of route km on lines operating at the ultimate
