SEAFORD - Service between Freeport and Babylon on the Babylon line was suspended today as the LIRR worked to upgrade its signal system.

LIRR president Helena Williams says the system improvements are vital to help give customers more of what they want: reliable train service.

"We strive everyday to deliver the best service we can with on-time performance," she says. "We know it's very important to our customers."

Crews are working a 14-mile stretch of track and modernizing a signal system that dates back to the 1960s. Williams says crews are about 50 percent done with the signal improvements that they need to make.
