MARC heat restrictions? Yes, really.
If you received a MARC commuter train alert about heat restrictions on the Brunswick Line Thursday, it's legit.
According to Maryland Transit Administration spokeswoman Cheron Victoria Wicker, this may be the earliest the restrictions have ever been implemented.
"They happen whenever there is a change overnight of 35 degrees or more," she said.
The steel rails can expand and contract because of the change in temperature.
The restriction typically mean that trains will travel 20 mph below their normal speed.
