The Long Island Rail Road says it doesn't have enough train cars to adequately serve it's booming ridership.

The railroad tells Newsday that the situation can result in dangerous crowding conditions and increased delays.

Statistics show the railroad operated with an average shortage of five train cars each weekday in 2018.

Officials say various issues forced several cars onto the sidelines throughout the past year. And officials pointed to a host of issues, including problems installing positive train control technology.

Last month, 20 cars needed to be pulled following the deadly collision on the tracks in Westbury.

But the railroad tells News 12 that most of the 20 affected cars have been returned to service. It says the issues resulted in short trains, but no cancellations.

In a statement, LIRR officials said, "LIRR employees work extraordinarily hard every day to ensure that our cars can be distributed as evenly as possible to reduce impacts of short trains. Under the new leadership of President Phil Eng, the LIRR has decided to retain and invest in the M3 fleet, and he challenged private industry to deliver the future M9A cars more quickly. We are working 16 hours a day to expedite testing of the new electric fleet of M9 cars so they can begin entering service in May, which will provide great relief to this challenge."
