Caltrain delays due to system-wide brownout

 

Commuter service on Caltrain was suspended for nearly an hour this morning due to a system-wide brownout.

The brownout began at 8:04 a.m. and service was restored around 9 a.m.

Delays of up to 57 minutes were reported at 9:18 a.m.

Caltrain officials apologized to customers on Twitter, calling the situation an "unprecedented scenario."

I'm guessing that the brownout affected the control system that facilitates the safe operation of the trains, not the trains themselves. I look forward to reading more about this and whether battery backup systems were available or not.

As our infrastructure becomes increasingly electrified and wirelessly networked, reliability will need to be upgraded across many older technology platforms like rail operation controls.

Per @Caltrain tweets this morning, the failure was in the signaling system.

The JPB/Caltrain operators need to do a better job at maintaining system integrity and backup systems.

One doesn't see these sort of failures on JR Central or Tokyo Metro.
