Having sweltered outside today for Gov. Martin O'Malley's twin transit press conferences, it comes as no surprise that there are heat restrictions on the tracks of both the Camden and Brunswick lines. Riders on those lines know they've enjoyed a mild summer to date and that they'd have to pay the pipe sometime.

If the delays are no more than the Maryland Transit Administration is advertising, they could amount to no more than "minor" disruptions. But the MTA, if it had any sense about customer relations, would stop using the word "minor" on its web site -- as it is currently doing at 5:30. Just calll them "disruptions," folks. Nobody likes to hear their own headaches described as minor.

When will they ever learn?
