(AP) — Public safety officials in Connecticut say about 50 people have been hurt after two commuter trains collided outside New York City. Four of those injuries were deemed serious.

No fatalities were reported following Friday evening’s collision near Fairfield on the Metro-North Railroad.

The rail line referred to it in a news release as a “major derailment.”

A spokesman for public safety officials in nearby Bridgeport says about 250 people were on the two trains that collided after one derailed.

The railroad says a train that departed New York City’s Grand Central station en route to New Haven derailed. A westbound train on an adjacent track then struck the derailed train.

Some cars on the second train also derailed as a result of the collision.

Amtrak suspended service indefinitely between New York and Boston.
