NEW YORK — New trains, new buses and a new train service on Metro will begin running on Wednesday on an expansion of the Northeast Corridor, a rail expansion that is under consideration in New York City and other parts of the country.

The new trains will begin arriving in the city in the spring and go into service later in the summer.

Metro’s expansion would take advantage of a rail line known as the L train, which has operated for decades along the Northeast corridor between New York and Philadelphia.

New York City is hoping to expand its rail network and get more people around, and has been working on a plan to increase rail service on the Northeast by as much as 5% annually.

“This is the largest rail expansion in New Jersey history,” Mayor Bill de Blasio said in a statement.

Since the start of the expansion, trains have gone from one train every 5 minutes to a full train every 2 minutes, and buses have gone up by more than 1,000 buses every day, he said.

More than 100,000 people are expected to ride the L Train every day during the expansion.

The L train was built in the 1930s and used to bring people between New Jersey and Philadelphia to work.

Now, trains will continue to run on the L Line between New Brunswick and Newark, but they will only be a stop, not a stopover.

Instead, riders will have to travel a longer distance, sometimes traveling nearly a half-mile, from Newark’s East Newark to Manhattan, where the trains will stop.

The length of the trip will vary depending on the train and its length, Metro said.

New cars and engines will be added to the L trains as they get older and become more expensive, Metro officials said.
