Original post: Plunging temperatures prompted Amtrak to suspend service between New York City and Albany, according to a spokesman.
The extreme cold was affecting signals and switches. Amtrak hopes to resume service later Monday.
"The sub-zero temperatures have caused some signals, switches and equipment to freeze, and as a precautionary measure, Amtrak has temporarily suspended service between New York City and Albany," the passenger rail agency said in a statement.
Some passengers were being transported via buses.
The spokesman said service between Washington and Boston was operating normally.
