SEPTA says multiple trips on the Airport, Fox Chase and Chestnut Hill West Regional Rail lines will be canceled Monday amid a railcar shortage due to a federal order. 

SEPTA is currently inspecting its Silverliner IV railcars after the Federal Railroad Administration ordered the Philadelphia-based transit agency to inspect the 223-railcar fleet following several fires on the model. 

The 9411, 412, 425, 802, 809 and 814 trains in the peak morning on the Airport, Fox Chase, and Chestnut Hill West Regional Rail lines Monday are canceled, according to SEPTA. 

The 9426, 9435, 436, 449, 9450, 9459, 460, 473, 821, 826, 833, 838, 845, 850, 857 and 862 on the aforementioned lines will be canceled later in the day, SEPTA said. 

SEPTA said there will be fewer cars for each train Monday, which will cause crowded conditions and skipped stations, especially closer to Center City. 

The Federal Railroad Administration initially gave SEPTA until Oct. 31 to complete an inspection of these railcars, but that deadline was extended until Friday.

This is a developing story and will be updated.
