NJ Transit will shut down at 8 p.m. and no one is sure when it will resume.

Governor Chris Christie made the announcement Tuesday that service would end at 10 p.m., but NJ Transit amended the announcement and said it would end at 8 p.m. NJ Transit said on Twitter that rail service may not resume until Thursday. "Service may resume Thursday depending on the condition of the tracks," according to the agency.

Limited bus service may resume Wednesday depending on the condition of the roads and equipment, the agency said. Christie said he doesn't expect rail service to resume Wednesday. "It is weather-permitting," he said.

"We would like to make Wednesday productive for everybody," he said at a press conference. NJ Transit had announced it plans to operate on a regular weekday schedule and cross-honor tickets from Monday, Jan. 26 through Wednesday, Jan. 28 to "minimize delays, and ensure service reliability and safety due to the approaching winter storm."

Cross-honoring gives "customers additional travel options during the expected winter weather conditions," allowing them to use their ticket or pass on an alternate means of transportation, such as rails, light rails, buses or private bus carriers.

However, customers are advised to regularly check NJTransit.com for the latest service information, as "there is potential for significant shutdowns of NJ Transit's rail, bus, light rail and Access Link service" due to the predicted severity of the storm.

NJ Transit also urges customers to use "extreme caution traveling in and around all transit facilities and when boarding or alighting buses and trains due to the expected icy conditions." And, according to their website, NJ Transit is "prepared to handle the impending winter weather."
