The brutally cold temperatures on Long Island pose a threat to Thursday's morning rush on the road and rails.

Even on Wednesday, Long Islanders did everything they could to contend with the cold. Long Island Rail Road riders in Hicksville were bundled up, and Oyster Bay Public Works crews hauled sand and salt to keep roads safe, especially during the day's brief but heavy snowfall.

Town of Oyster Bay Supervisor Joe Saladino said the town made sure all the roads were pretreated. He also said it saves taxpayers money on crews because they didn't have to work after hours.

Delays due to signal issues in Jamaica, Queens, added to the frustration for chilly commuters.

LIRR officials said crews are ready to handle weather-related issues like broken rails.

Commuters told News 12 that they worried about how difficult their Thursday rail ride could be.

The LIRR will keep waiting rooms open 24 hours a day until Friday to keep commuters warm.

Oyster Bay town officials opened warming centers and continued monitoring conditions to keep roads from getting slick.
