While the investigation continues into the deadly Amtrak derailment near DuPont, Washington, the clock continues to tick on the implementation of Positive Track Control (PTC). The deadline is Dec. 31.
PTC integrates new satellite tracking (GPS) and trackside technology for passenger, freight and commuter rail service. It is designed to instantly feed mountains of detailed and complex information to control centers and moving locomotives to automatically stop speeding trains from going off the track and colliding.
Neither the track on new Point Defiance bypass between Tacoma and Olympia nor the engines propelling Amtrak Train 501 on its inaugural high-speed run were equipped with new anti-crash system.
“The lightly used freight line, first laid out in 1891, would be converted into a bypass route to allow passenger trains to avoid a congested section of tracks and tunnels that run along Puget Sound in Tacoma,” the Wall Street Journal reported.
The Dec. 18 train crash occurred on track upgraded by the state of Washington to allow trains to reach speeds up to 80 miles per hour (mph). High-speed commuter rail was planned to relieve vehicle traffic congestion on Interstate 5 between Portland and Seattle.
