The Long Island Rail Road is reporting system-wide delays due to broken rails.
Transit officials say there were five broken rails that caused 15-20 minute delays.
LIRR spokesman Aaron Donovan says railroad officials need to investigate whether temperatures in the single digits may have contributed to the broken rails. He says cold temperatures are usually a factor in these situations.
Two of the broken rails were in Westbury, one was in Babylon and another was in Great Neck.
