SEPTA Warns Of ‘Slippery Rail’ Delays On Train Lines

Falling autumn leaves look nice, but they can cause slick conditions on SEPTA’s Regional Rail lines.

The seasonal issue, which is known as “slippery rail,” happens when crushed leaves cause a slick residue on the tracks, SEPTA officials warned.

The coating reduces friction between train wheels and the steel rails, which creates slick surfaces that force engineers to lower speeds to maintain safe operations.

The reduced speeds are needed along inclines, declines, and on approaches to station platforms, according to SEPTA.

As part of their effort to fight the buildup, SEPTA runs three specialized wash trains every night.

SEPTA officials explained that the trains pressure-wash the tracks with a mixture of water, gel, and sand designed to scrub away the oily residue.

While the treatment removes debris from the rails, transit officials stated that riders may still encounter service delays at times.

The duration of slippery rail season hinges on autumn weather patterns, but the condition typically lasts from late October through mid-December after trees have shed their remaining leaves.

SEPTA said that while minimizing travel disruptions remains a priority, passenger safety takes precedence.

SEPTA officials advise commuters to budget extra time for their trips and to remain alert, as slick conditions can occasionally cause trains to glide past station platforms.

Riders are encouraged to check for real-time service updates on SEPTA.org or via the official SEPTA mobile app, and to monitor audio announcements while waiting on station platforms.
