Following the deaths of two workers in an October accident, Oakland, Calif.-based Bay Area Rapid Transit District (BART) suspended a decades-old practice that made workers solely responsible for their own safety on the tracks.
The practice, called “simple approval,” allowed workers to walk along tracks in pairs, with one person serving as the lookout as the other inspected tracks.
“Beginning after the accident, all way-side work that is going to take place has to be done with work clearance, meaning trains will either have to stop, single track or go into ‘road manual,’ which is no faster than 25 miles per hour,” explained James K. Allison, spokesman for BART.
Although fatal accidents had occurred on BART tracks before, the agency felt “simple approval” gave workers the primary responsibility for their own safety, and therefore, they would be more vigilant while on the tracks, Allison added.
Following the accident, BART continues to explore all options to ensure rail worker safety in the future, said Allison.
In the wake of the accident, the California Public Utilities Commission established a set of new regulations to improve rail transit worker safety on public transit systems, making California the first state in the nation to adopt such comprehensive transit safety rules.
The decision will strengthen safety rules to protect roadway workers by adopting a series of strict requirements on rail transit agencies, including implementing a safety training program with a series of strict requirements to ensure workers are well-versed in the methods required to work safely and effectively; maintaining written flagging procedures to enhance safety on railway tracks; ensuring industry standard personal protective clothing for workers; and ordering the rail transit agencies to research and plan/implement additional roadway worker technologies such as early warning alarm technology, back-up alarms and positive train control.
Around the nation, some transit agencies have already begun exploring worker safety technologies that work in tandem with their existing protocols.
The Metropolitan Atlanta Rapid Transit Authority (MARTA) partnered with Bombardier Transportation for a demonstration project testing its TrackSafe solution, which creates improved location awareness for track workers and train operators through Radio Frequency Identification (RFID) and other advanced technologies.
“As the workers walk along the track, they tag in using an RFID chip embedded inside their badge, which notifies the system where they are along the right-of-way,” said Mark Willer, product & development manager for Bombardier. “There are also sensors that detect where the trains are, so when they are a certain distance away from the area workers have tagged into, the system alerts track workers that there is a train approaching by sounding a siren and flashing strobe lights.”
The Federal Transit Administration (FTA)-approved test project was conducted between the Ashby and Bankhead stations along MARTA’s Green Line and completed in summer 2012.
“One of the key objectives of the study was to understand how TrackSafe would impact rail operators, some of our central controllers and folks who work in our right-of-way,” said Abhay Joshi, project manager at MARTA. “The concept itself was whether or not folks exposed to the system were getting additional alerts early in the process and that’s essentially what it did.”
Additionally around 2008, the Maryland Transit Administration’s (MTA) Metro subway system teamed with Protran Technology, the FTA and the Transportation Research Board to develop a system that would give an advanced warning to track workers of an approaching train and also give advanced warning to the train operator of workers ahead.
“Protran Technology developed a system that fit into our operating procedures and required no wayside fixed equipment, meaning trains could operate while the system was implemented,” said Paul Shepard, spokesman for MTA.
The Protran ProTracker Train Device (TD) is mounted in the cab of a train and alerts, both audibly and visually, the train operator of personnel near the train tracks who are wearing the Protracker Personal Alert Device (PAD). A message can also be sent to the control center and display the worker location in real time.
While Shepard explained the MTA hadn’t experienced a recent accident before implementing the Protran solution, the agency has been pleased with the extra layer of protection it has provided for track workers.
“Since the implementation of the Pro-tran TD and PAD systems, the MTA has had zero close calls and zero fatalities while the system is in use,” he said.
