The base subway and bus fare in New York City would rise to $2.50, up from $2. A 30-day MetroCard would cost $103, up from $81. A monthly ticket on the Long Island Rail Road for a commuter who travels between Ronkonkoma and Pennsylvania Station would increase to $352, up from $278.

These are some of the fares that New Yorkers would pay under a drastic proposal that is expected to be approved by the Metropolitan Transportation Authority on Wednesday.

And those higher fares will buy even less: the authority’s board is also expected to approve deep service cuts.

The proposal — which also includes higher tolls on the authority’s bridges and tunnels — was approved on Monday by the board’s finance committee, whose members said they were forced to act because the State Legislature had not passed a financial rescue package.

“We’re going to vote the fare hikes,” said H. Dale Hemmerdinger, the authority chairman, referring to Wednesday’s board meeting. “It’s very painful to everybody who uses the system.” He called the service cuts “horrific.”

Asked whether he had a message for lawmakers in Albany, Mr. Hemmerdinger said, with his voice cracking slightly: “How about just, ‘Help.’ ”

In Albany, Gov. David A. Paterson, who supports a transit rescue package, said the authority should not postpone a vote on the fares. The authority has said that if the Legislature should approve a rescue package after the fare vote, the board could revisit the fare and toll increases and service cuts.

“Delaying action, to me, would just ring too true of what’s gone on in Albany too many times,” Mr. Paterson said. The governor and the Assembly speaker, Sheldon Silver, support a rescue package that includes a smaller fare increase of 8 percent, a new tax on payrolls and tolls on the East River and Harlem River bridges. But the package has been held up in the Senate, where several Democrats oppose new tolls.

If approved, the new subway and bus fares would take effect on May 31. New commuter rail fares would go into effect June 1, and the higher tolls would take effect in mid-July.

The new fares and tolls are meant to increase revenue by 23 percent. But to achieve that, the price of some services would go up by quite a bit more.

Among the hardest hit are riders of Long Island Bus, which primarily serves Nassau County, where a single ride would cost $3.50, up from $2. And riders would no longer be able to use unlimited-ride MetroCards.

Proposed increases for disabled riders in New York City on the door-to-door Access-a-Ride service were scaled back, however. The authority had proposed raising those fares to double the base subway fare. Instead, the fares will continue to mirror the base subway fare, which is set to rise to $2.50.

Under the proposal expected to be approved on Wednesday, weekly MetroCards for city subways and buses would rise to $31, from $25.

Express bus fares would rise to $6.25, from $5.

The bonus on pay-per-ride MetroCards would remain at 15 percent, which means that a bonus ride would be earned after the purchase of seven rides. Viewed another way: the cost of a ride on a bonus pay-per-ride MetroCard would be $2.17, up from $1.74 today.

On Metro-North Railroad, a person commuting between White Plains and Manhattan would pay $243 for a monthly ticket, up from $191.

One-way E-ZPass tolls on the authority’s major bridges and tunnels, like the Robert F. Kennedy Bridge and the Brooklyn-Battery Tunnel, would rise to $5.26, from $4.15.

The far-reaching service cuts include the elimination of 35 bus routes and the elimination of the W and Z subway lines. Off-peak service on subways and buses would be cut and commuter rail service would be trimmed. About 1,100 transit workers would be laid off. The service cuts would go into effect over the next several months.

The combination of higher fares and diminished services are meant to help close a $1.2 billion budget gap this year. But officials said on Monday that the authority’s finances continued to worsen, and further measures to balance the budget might soon be required.

Revenue from taxes on real estate transactions have continued to plummet. Through mid-March, the authority received $97 million in such taxes — $123 million less than it expected to receive and $210 million less than it took in during the same period last year.
