Around 10 a.m. Thursday an Amtrak contractor struck a 24-inch gas main on the property of Penn Station in Baltimore, a utility spokeswoman said.
Baltimore Gas and Electric Co. responded to the scene and were continuing work on shutting off the gas line at around 2 p.m., said Rachael Lighty.
Only buildings on the Penn Station property are expected to lose gas service because of the leak, she said, but BGE is having employees canvass the area to ensure no residential gas users have lost service.
Anyone who smells gas in the area around the station should report it to BGE by calling 410-685-0123.
The leak caused one MARC train to be delayed for 17 minutes Thursday morning. Amtrak has not reported any significant delays because of the leak.
Traffic was diverted from North Charles Street because of the accident.
