Norfolk Southern Railway Company (NSR) filed a petition requesting permission for the trackage rights granted by CSX Transportation, Inc. (CSXT) to expire as per their agreement. These trackage rights, over a 95-mile rail line, were intended to reroute NSR's traffic while CSXT's Howard Street Tunnel (HST) in Baltimore undergoes construction. The Surface Transportation Board (STB) decided to grant NSR's petition, allowing the trackage rights to end once the HST project is completed and NSR resumes using its original route through the tunnel. The decision includes measures to protect employees affected by the change in trackage rights.
Simple Explanation
Norfolk Southern Railway wants to stop using some shared train tracks because they have finished fixing a nearby tunnel, and the train board said they can do that. They made sure to have some rules to help train workers who might be affected by this change.
