Amtrak is expanding its Acela Express service in April.

Weekend Acela Express service on the Northeast Corridor between Boston and New York City will see an additional round trip on Sunday.

Amtrak said schedules will also be adjusted to add more departures Saturday morning and Sunday evening, when customers have requested more service.

The changes will go into effect April 8.

“Our responsibility is to listen to our customers and continually improve our product to make sure Amtrak is always recognized as a smarter way to travel,” said Mark Yachmetz, Amtrak Vice President of NEC Business Development.

The carrier, to meet increasing demand for high-speed rail service and additional capacity on the Northeast Corridor, has contracted with Alstom to produce 28 next-generation high-speed trainsets that will eventually replace the existing Acela Express equipment.
