While NYC Transit says the problems with Metrocard vending machines have been solved, apparently some stations' machines are still touch-and-go. But whether that's related to the systemwide issue or just par-for-the-course Metrocard vending machine, we'll never know. The clerk at the 53rd Street and Lexington Avenue line told the Daily News that "major, systemwide failures hit about once a month - and that on a regular basis, at least half of the machines in her station are out of commission several times a week." Yeah, that sounds about right.
