Metro-North train service has been restored on all three lines, Hudson, Harlem and New Haven. Customers should expect significant residual delays.
At 7:45 p.m. power to the computer system that controls all Metro-North train movements was interrupted.
Rail traffic controllers took the immediate safe course of action and instructed all train engineers, via radio, to bring their trains to a stop at the first, nearest station. Customers were able to exit the train if they wished.
If an interlocking was before a station, the train was stopped before entering the interlocking. Signal maintainers were dispatched to those interlockings to take local control so these trains could proceed to the nearest station platform.
All trains had power, and there was heat and light on board.
Electricians immediately began troubleshooting and began establishing temporary power, which was achieved at about 9:30 p.m.
The railroad is slowly returning to service. Amtrak also was affected.
