A 200-car train broke down in Coraopolis this morning, blocking all train crossings in the town. The train began moving just before noon today. Six crossings in the town were blocked by the disabled train, including Broadway, Mulberry, Mill, Main, Watt and Thorn streets. The coupling broke on the train and separated a car. To fix the train, all couplings had to be checked. Parts of the trains were stuck in Coraopolis and others in Moon. A medical emergency was reported on the North Side of the tracks while the train was stuck. Paramedics had to ride in a public works pickup truck already on that side of the tracks.
