The trains that run along about 135 active miles of rail in Lancaster County can at any point be carrying hazardous material. But real-time information on those materials is nearly impossible to get, because in a post-9/11 environment, railroads aren’t required to share that information. That secrecy means emergency responders might not know what hazardous materials they’re dealing with until they reach the scene, and that there is no single, consistent way to find the information at the scene – all of which could potentially slow their response or put them in danger. State and federal legislators are calling for greater transparency, as ongoing Congressional testimony has shown first responders weren’t able to access information about the chemicals in the overturned cars right away, and the railroad has been under fire for response time.
