Damage to Metro signaling equipment caused three hours of single-tracking on the Orange, Silver and Blue lines on Saturday morning, August 10. The delay, officially reported as a " signal problem ," stemmed from a work unit being used during overnight trackwork that caused damage which required repairs. Actually this wasn’t a software malfunction, a prime mover collided with a signal or signals at D98 around 3:30am. — M (@TunnelRatDC) August 10, 2019 The incident occurred at approximately 3:35am on Saturday, August 10 when it appears indications in the Rail Operations Control Center (ROCC) alerted controllers that something had caused a signal or signals outside Stadium-Armory in the "D&G junction" to malfunction. Based on audio recordings of the incident, it appears that a trackwork unit, SM03, was the closest of two units in the area at the time of the incident, and likely the one which caused damage to the signaling equipment.

Four hours of single-tracking on the Red Line on Wednesday, July 31 was caused by improperly-stored rail that had just been replaced, according to Metro radio transmissions analyzed by Metro Reasons. Equipment on a train came into contact with the rail just after 5:30 am which brought down power to the tracks, and led to disruptions throughout Wednesday's rush hour. That surely was some long *scheduled* maintenance. Rush hour is a DISASTER this morning (9 hours later)! pic.twitter.com/G5VtCgdN3H — Jordan Dale (@FrankJordanDale) July 31, 2019 Chronology Metro scheduled a  nightly trackwork area  during the week of July 29th through August 1st between Fort Totten to Takoma in order to perform 'rail renewal ' - that is, replacing the rails ("tracks") which trains run on top of. The work area for the evening of July 30th was scheduled to begin at 10pm, and the Roadway Worker In Charge (RWIC) requested the area on time at 9:12pm. The overnight work ran late

A signal issue at the Rosslyn Metro station caused major delays, offloads, and train reroutes on Thursday, August 1 on the Orange, Silver, and Blue Line trains. Delays began subsiding around 9:45 am after the end of morning rush. Delays westbound began around 7:40 am and quickly grew. Similar delays eastbound began occurring around 8:30 am after WMATA Automatic Train Control (ATC) personnel arrived on scene. Automatic electronic equipment ("automatics") at the Rosslyn junction where tracks diverge to head to either Arlington Cemetery or Court House typically detects the destination of the next train entering the station. Once detected, the equipment automatically moves the switch into the correct position so that the train ends up at the right location. Current status on the OR/SV/BL lines. Some trains are offloading and reversing at various points to reduce the number of trains through Rosslyn. #wmata pic.twitter.com/Z3ARlf9IXz — Metro Reasons (@MetroReasons) Aug
