LIRR: On or close after 'slip slide' delays

The Long Island Rail Road was on or close to schedule early Friday afternoon after "slip-slide," a slippery rail condition caused by fallen leaves, created scattered delays during the morning commute.

The condition, caused by "crushed leaves on the rails" that the railroad said leave an "oily residue" buildup on rail surfaces, forced some trains to operate at slower-than-normal speeds.

In an online explanation, the railroad said: "One thing you will notice is that under extreme conditions, we reduce speeds through problem areas out of concern for your safety. While this may result in a slight delay to your service, it ensures a safer operation while also preventing a greater delay because of wheel damage."
