Service on the Port Jefferson branch of the Long Island Rail Road has been restored after being temporarily suspended Friday morning when a train struck a man in Huntington, police and railroad officials said.

Railroad spokesman Aaron Donovan said the man survived and was taken to Huntington Hospital with severe injuries to his right leg and a possible broken right clavicle.

MTA police said they are investigating the incident, which occurred as 5:06 a.m., as a possible suicide attempt. Witnesses said the man, who is 19, jumped from the platform to the tracks but then tried to dodge the train.

Donovan said the train was traveling at 15 mph.

Though full service was restored by 7 a.m., the railroad said commuters faced residual delays of up to 90 minutes between Huntington and Hicksville and an hour between Huntington and Northport. There were also delays between Hicksville and Penn Station.

It was not clear how many trains were affected.

Service between Huntington and Hicksville was restored at 6:12 a.m., and service between Huntington and Northport was restored at 6:58 a.m.
