Positive Train Control (PTC) is a rail safety technology being widely implemented across US commuter rail lines to avoid train accidents due to human errors.
Positive Train Control integrates multiple technologies, including global positioning system (GPS), on-board computers and digital communications. These measures aim to monitor train movements, detect upcoming conditions and prevent collisions between trains, in addition to over-speed derailments, invasion into work zones and improper train movements.
The Rail Safety Improvement Act (RSIA) was enacted by the US Congress in 2008 and mandates all commuter lines in the country, involving 70,000 miles of track and 20,000 locomotives to be equipped with PTC by the end of 2015.
Following an interesting video demonstrating that’s not a realistic deadline.
