CTA Yellow and Purple lines were running with delays Tuesday after being disrupted due to track switching problems at Howard Avenue.
Yellow Line service was completely suspended earlier, while Purple Line trains were operating only between Linden and South Boulevard, the transit agency said in an alert.
The issue was first reported about 12:20 p.m. by the Chicago Transit Authority.
Train service on both lines resumed normal service with residual delays around 4 p.m., the CTA said.
Both lines experienced another hours-long suspension a week ago after more than a foot of snow fell on Chicago, causing switch problems at Howard.
On Monday, Yellow Line trains were suspended after a “train incident” at Skokie.
