A collision between a CTA Yellow Line train and a piece of snow removal equipment at the Howard rail yard in Rogers Park left 38 people injured and 23 of them hospitalized. The crash occurred just after 10:30 a.m. and involved a two-car Yellow Line-Skokie Swift train. The train rear-ended a snow fighter locomotive used for clearing snow from the CTA tracks during the winter. It remains unclear why the machine was sharing the same track as the train.

During a press conference, the Chicago Fire Department stated that 38 people were evaluated by medical personnel, with 23 being transported to area hospitals. At least three people were critically injured, but none of the injuries were life-threatening. Among the injured were four children and seven CTA employees. The NTSB is expected to release more details into the investigation.

Audio obtained from the CTA traffic control tower reveals a warning about maintenance equipment on the tracks prior to the collision. The control tower repeatedly instructed the train operator to stop, but it is unclear if the train involved in the crash was the one being referred to in the audio. Transportation experts suspect a combination of technology and human error may be responsible for the incident.

The CTA has not provided further updates regarding the cause of the collision.
