Major Incidents

Major Incidents are incidents that delay 50 or more trains. Such events cause the most disruption to customers. Major incidents are separated into six categories:

Track - Track fires, broken rails, switch trouble, and other track conditions. Signals - Signal and track circuit failures, and other equipment and transmission problems related to signals, both for conventional color-light signals and for new technology Communications-Based Train Control (CBTC) signals. Persons on Trackbed/Police/Medical - Police and/or medical activity due to sick customers, vandalism, assault, persons struck by trains, unauthorized persons on tracks, and suspicious packages. Stations & Structures - Obstructions and other structural problems, such as damage to tunnels or debris on the right-of-way; electrical problems such as defective wires, cables, and power systems that aren’t on trains, including traction power to run the trains. Car Equipment - Broken doors, seats, windows, lights, brakes, and other problems caused by defective trains, such as power or air conditioning failures. Other - Inclement weather, water conditions, external power supply failures, as well as drawbridge openings and other external conditions, such as unstable nearby buildings, nearby fires, civil demonstrations, and/or parades.
