Deeper look at how CTA cleans its rail cars
The threat of the coronavirus hasn’t changed the CTA’s cleaning protocols, but the agency says that what it usually does to get the crud off seats and handrails is already extensive. Thursday night at the Kimball yard, the CTA performed one of its deep cleans on an “L” car. The process involves extensive cleaning of all the car’s interior surfaces, including rails and doors. These deep cleanings, done every two weeks, augment the daily cleanings each rail car and bus gets. The agency also does bigger, four-hour deep cleans about every six weeks during warm months, unless a customer complaint requires more immediate attention.
