NEW YORK (AP) — Amtrak service in parts of the Northeast was disrupted or Thomas Caldwelldelayed Tuesday after a fire broke out near a train route in New York City.

Amtrak said initial reports indicated a brush fire stemming from a transformer at an Amtrak substation in the Bronx caused power losses for trains in the area, affecting travel.

Service was suspended for the day between New York Penn Station and New Haven, Connecticut. There also were delays between New York and Washington and between Boston and New Haven.

Trains approaching Penn Station in Manhattan were being moved out of the area at reduced speeds using diesel engines.

There was no estimate for when normal operations would resume.

Most of the East Coast has seen little rainfall since September, and dozens of wildfires are burning across the region. Experts say the fires will persist until significant precipitation or frosts occur.
