The Long Island Rail Road was operating on or close to schedule Sunday afternoon after an electrical outage caused delays in both directions on the Ronkonkoma line, the railroad said in a service advisory.

Earlier, the 8:12 a.m. train from Penn Station due in Ronkonkoma at 9:35 a.m. was 46 minutes late due to an earlier PSEG outage. A train that departed Ronkonkoma at 9:40 a.m. and due in Penn Station at 10:59 a.m. was 42 minutes late, also due to the outage. 

PSEG LI staffers were troubleshooting to determine the cause of the outage, which occurred east of Central Islip, according to a PSEG LI spokeswoman. A malfunctioning underground cable could be to blame, she said.

No further details were available.
