New Yorkers will soon be asked to pay more to ride trains and buses that just weeks ago suffered the severest service cuts in a generation. The series of fare increases will be unveiled on Wednesday by the Metropolitan Transportation Authority.

By Jan. 1, when the increases would take effect, the heaviest users of the city’s subways and buses could be paying as much as $104 instead of $89 for a monthly system pass. Drivers who use E-ZPass on many of the city’s tunnels and bridges would pay 10 percent more per trip, and rail commuters could face the frustration of longer lines to buy tickets.

The unlimited subway and bus MetroCard, which pushed ridership to record levels after its introduction in the 1990s and revolutionized the way New Yorkers imagine their transit system, could also be on the way out. One proposal would place limits on how many rides could be taken on monthly and weekly passes.

Officials at the authority say they can avoid additional service cuts this year as a result of layoffs and cost-cutting. And instead of an across-the-board fare increase, as in years past, the authority would make a variety of smaller tweaks to the myriad ticket types available.
