Car Crash Berks Pennsylvania in Berks, Pennsylvania: Extreme heat and a delayed arrival of Union Pacific's Big Boy No. 4014 steam locomotive triggered a mass casualty incident Thursday afternoon at the Reading & Blue Mountain Railroad Outer Station in Muhlenberg Township, Berks County. Temperatures reached 106 degrees while crowds waited more than an hour for the train, and emergency crews began treating heat-related illnesses before the locomotive arrived. More than 100 people required on-scene medical care and 35 were transported to hospitals, prompting a mass casualty declaration and a regional mutual-aid response.
