Switching the automation off after Fort Totten took about a day. Switching it back on took fifteen years and a line-by-line sign-off, even though investigators blamed train detection, not the driving mode.

Metro trains drove themselves between stations from the system's 1976 opening until June 2009, when WMATA put the whole network into manual mode within about a day of the Fort Totten rear-end collision that killed nine people. The NTSB traced the crash to track circuit modules that stopped detecting a standing train and to a verification test WMATA never rolled out system-wide — not to the driving automation that was turned off. Automatic train operation came back line by line: Red on 15 December 2024, Green and Yellow on 23 May 2025, Blue, Orange and Silver on 15 June 2025, each step needing the safety commission's concurrence. Operators stay in the cab, working the doors and watching the track.

Live 📅 since 1976

📊 Impact

WMATA figures, June 2025: end-to-end travel times down 8 minutes on the Red Line after several months under ATO, 1-2 minutes on the Green and Yellow lines and about 3 minutes each on the Blue, Orange and Silver lines from 22 June 2025; WMATA reports no red signal violations by trains in ATO. Counterweight, press-reported April 2025 and not independently audited: 217 station overruns under ATO since December 2024, roughly ten times the manual-mode rate, which WMATA called 'a reliability problem and not a safety problem'; the safety commission withheld concurrence for expansion until WMATA scheduled a software update and a new antenna normalisation procedure for 7000 Series railcars.

🎓 Lesson

Switching working automation off after a disaster takes a day; switching it back on took fifteen years, a regulator's line-by-line concurrence and a fix to how railcars sense their own position — even though the crash investigation blamed train detection, not the driving mode.

What the mapping says
The NTSB record establishes the collision and its toll: 'Nine people aboard train 112, including the train operator, were killed', with 52 people transported to hospitals.
Caveat
The one-day timing of the switch to manual mode is the operator's decision rather than an NTSB finding; the investigation documents the crash, not the mode change.

The May release reports Red Line end-to-end trips cut by 8 minutes since December with no red signal violations under ATO; the June release gives about 3 minutes on Blue, Orange and Silver from 22 June and 1-2 minutes on Yellow and Green. Independent trade press confirms the same per-line figures.
Caveat
Operator figures, labelled as such in the entry. The trade-press confirmation repeats the operator's numbers rather than measuring independently.

What the mapping says
The trade report gives 217 trains under ATO overrunning station stops since December, about ten times the number under manual driving, 38 per cent of them by three or more cars, with doors staying shut during an overrun. WMATA confirmed the count, called it 'a reliability problem and not a safety problem' and pointed to zero red signal violations in ATO. The cause was traced to false marker coil detection.
Caveat
Press-reported and not independently audited; the entry labels it as such. The page returned an error to automated fetching, so existence and content were confirmed through two independent search passes and corroborated by the safety commission's own filing.
