Just when you finally managed to stop pondering all of the things that could go wrong when riding the NYC Subway, it turns out that the computer system that controls the trains crashed for a few minutes yesterday.
It was only “down” for a few moments. However, when it came back online, the system was unable to find many of the trains in the system.
The system that crashed only controls the numbered lines. While the system went down and recovered, many trains were forced remain in stations or mid-tunnels while dispatchers manually radioed individual trains to determine their location. Yikes.
Perhaps some of the MTA employees that read SUBWAYblogger could enlighten us on why the computer can’t locate trains after a reboot. I assume the trains have to pass some sort of sensor on the track. So if the trains weren’t moving, they hadn’t passed over a sensor since the reboot.
