A-train cancels late Friday, early Saturday trains over summer for testing


Starting May 18, the two latest DCTA A-trains on Friday nights and the earliest one Saturday mornings will be cancelled as DCTA works to implement a Positive Train Control system. The modified schedule may continue as long as September.

The Friday trains in question arrive in Old Town Station at 10:40 p.m. and 11:37 p.m., respectively. The last train north will leave Old Town at 8:20 p.m. and the last train south will leave at 9:42 p.m., according to the A-Train schedule. The suspended Saturday morning train departs north from Lewisville at 7:40 a.m. For the duration of testing, the earliest northbound train will leave at 9:27 a.m.

According to the U.S. Department of Transportation, PTC was required by Congress in 2008. The deadline to implement it was originally Dec. 31, 2015, but it was pushed back to 2018. A PTC system is an automated system designed to prevent train-to-train collisions, derailments and unplanned train movement.

According to DCTA’s post on the matter, it is the first transportation district in the state to begin testing on the system. The Lewisville Texan Journal will update this story with more information on DCTA’s specific PTC system next week.
