NEW YORK (CBSNewYork) — Human error was to blame for a computer glitch Thursday that forced Metro-North to suspend all trains on three of its five lines, Metropolitan Transportation Authority chairman and chief executive officer Thomas F. Prendergast said.
As CBS 2’s Andrea Grymes reported Friday evening, the result of the glitch was a swarming crowd of stranded Metro-North and Amtrak passengers in Grand Central Station, and thousands more people trapped on trains.READ MORE: NYPD: Craig Tamanaha Charged With Arson For Setting Christmas Tree On Fire Outside FOX News Building
Metro-North took full responsibility for the glitch.
“We deeply apologize to all of our customers who were affected,” said MTA spokesman Adam Lisberg.
But as CBS 2’s Jessica Schneider reported, the apologies were not good enough for everyone. Some were demanding much bigger consequences.
Around 7:45 p.m., the computers that run the railroad’s signal system lost power when one of two main power supply units was taken out of service for replacement, Prendergast said.
Lisberg said the backup system that should have kept the power going the problem did not work.
“What we thought was the functioning backup turned out this disconnected wire, and it didn’t have full functionality, and this cascaded into the whole railroad being shut down for almost two hours,” Lisberg said.
As a result, more than 50 trains on the Hudson, Harlem and New Haven lines were brought to a stop for safety reasons as electricians worked to hook up temporary power and get the signal system back on track.
