We had an unusual occurrence in Wichita yesterday. A cement truck overturned rounding a corner that happened to include a railroad crossing. As the overturned truck's cab laid above the tracks, a Sedgwick County sheriff's officer dragged the driver to safety moments before the locomotive struck.
According to news reports, bystanders ran up the track trying to signal the train, going 40 mph, to stop. While they were certainly well-intended, that not the right strategy. The train's crew might not have known what the bystanders were seeking, plus even if they got a hundred yards or so up the track, that is not nearly enough time to stop.
Here is what to do if you ever encounter a similar situation:
That telephone number goes to the railroad's "service interruption desk." They will immediately contact the dispatcher handling the train and get them to stop. Give the person who answers the emergency number the information on the placard.
Even in rural areas without an electronic crossing, the number is affixed to the crossbuck.
This is the far more effective, and safer, way to get a train stopped in an emergency.
