Deactivated

On Friday an Amtrak train, traveling at 79 mph, killed a 26 year old woman in the Chicago area. The train plowed into her car.

There was no crossing signal. Crews had been working on the signal equipment, and messed it up:

Canadian National crews tried to resolve the problem and thought they had remedied it, officials said. But the workers actually deactivated the warning system, creating an unprotected crossing that provided motorists no indication of oncoming trains, officials said.

They thought they had remedied it. Okay. But did they test it?

To be sure of saving lives

before the train arrives

a test

is best.
