Most of the nation's railroads are legally required to implement an advanced safety system called Positive Train Control (PTC) by December 31, 2018. NJ Transit is no exception, but the railroad has been widely cited as being far behind schedule in its implementation program; a number of other railroads, including Amtrak and Pennsylvania's SEPTA commuter system, have completed their PTC installation programs, or nearly so. The system is said to be able to prevent many rail accidents by taking control of a train if the engineer fails to observe signals or track speed limits. In theory, if PTC is not in place by year's end, NJT might be forced to shut down. Extensions are possible, but only if the Federal Railroad Administration (FRA) is satisfied that a railroad is making acceptable progress toward implementing PTC, and has a plan in place to complete its PTC program. As reported by Curtis Tate for North Jersey Record, on June 26 NJT received FRA approval for a plan that would allow NJT another two years to complete installation. NJT spokesman Jim Smith said that NJT had made substantial progress since a March 31 report that showed little progress during the first quarter of 2018. To implement PTC, NJT needs to install equipment on more than 400 locomotives; 67 had been equipped so far. 66 of more than 100 radio towers are now in place, and 793 of more than 1000 employees have received PTC training. Smith said that NJT is confident that it will receive the two-year extension it is requesting.
