Was there a typo here ? 1500 times $2.10 is only $3150 - not close to $29K. However, it's probably alot more than 1500 riders after a late playoff game.
One idea would be for metro to add a surcharge to the fare - maybe another $1 higher or the fare that's used during rush hour. It would take some programming into the system and there may not be enough time now. But if they charge rush hour fares, the programming change for after midnight fare would be minimal. They could continue this on weekends as well.
I find it hard to believe that Metro does not make the $29K back from riders after midnight. It's only 1500 riders at $2.10, and if you are talking Silver Spring, Bethesda, King Street, and Ballston, and further out, then it is an even higher fare.
This really sounds like an opportunity for Ballpark Bus. hope those guys make a killing.
