WASHINGTON — Many commuter and freight railroads have made little progress installing safety technology designed to prevent deadly collisions and derailments despite a mandate from Congress, according to a government report released Wednesday.
The technology, called positive train control or PTC, uses digital radio communications, GPS and signals alongside tracks to monitor train positions. It can automatically stop or slow trains to prevent them from disobeying signals, derailing due to excessive speed, colliding with another train or entering track that is off-limits.
The Federal Railroad Administration report shows that while some railroads have made substantial progress, others have yet to equip a single locomotive or track segment with the technology, or install a single radio tower.
Congress passed a law in 2008 giving railroads seven years to put the technology in place, and last year extended that deadline for three more years after railroads said they were unable to meet the first deadline. The law extending the deadline to Dec. 31, 2018, also allows the railroad administration to grant additional extensions for two more years to railroads that have installed PTC but are still testing systems.
