Maryland officials are still trying to limit the fallout from MARC’s recent “hell train.”

Some 900 commuter train riders received a voucher for a free ride after their train was stuck for two hours in sweltering heat without air conditioning on June 21.

But on Tuesday, the Maryland Transit Administration said it is upping the ante with five free VIP passes, which are each good for one round trip in the next three years. To receive them, riders have to have been on the 538 train that day. The form must be submitted by Aug. 13.

The ride, which commuters and even Gov. Martin O’Malley labeled with the “hell”epithet, has prompted a multi-agency investigation, policy changes on the commuter train service and become fodder for sparring in the Maryland governor’s race.
