PHILADELPHIA — Trains on three of SEPTA’s Regional Rail routes have been canceled for the Monday morning commute.

SEPTA posted a statement Sunday night saying, “the service is currently running with extremely limited vehicle availability due to ongoing safety inspections of our Silverliner IV fleet.”

Trains on the Airport, Fox Chase, and Chestnut Hill West lines are affected.

SEPTA said, “In order to provide more reliable service for the Monday morning commute, the following AM peak hour trains will be canceled in advance on the Airport, Fox Chase and Chestnut Hill West lines: 9411, 412, 425, 802, 809 and 814.

The transit agency says additional trains will be canceled later in the day on Monday

“The following additional trains will be canceled later in the day: 9426, 9435, 436, 449, 9450, 9459, 460, 473, 821, 826, 833, 838, 845, 850, 857, 862.”

Riders should expect fewer cars for each train, causing crowded conditions and skipped stations, especially stations closer to Center City, according to the transit agency.
