On November 16, 2023, a Chicago Transit Authority (CTA) passenger train collided with maintenance equipment north of Howard station, injuring 16 people.

[1][2] At 10:39 a.m. local time (07:50 UTC) on November 16, 2023, a Yellow Line passenger train, carrying 30 passengers and 1 operator, approaching its terminal at Howard station at 26.9 mph (43.3 km/h) collided with stopped snow-removal equipment, carrying 6 employees, on the southern track.

[5][8] The following day, the National Transportation Safety Board (NTSB) started an investigation into the crash.

[9][2][10] Initial news reports suspected the operator to be incapacitated or in error;[11] however, a preliminary announcement from the NTSB indicated that the CTA had underestimated its trains' braking distance, compounded by the effects of slippery rails.

[12][13] In a preliminary report released on December 12, 2023, the NTSB found that, at the time of the incident, the snow-removal equipment had stopped 370 feet (110 m) north of a red signal.
