Amtrak implements heat restrictions between New York City, Philadelphia

NEW YORK CITY (WABC) -- Amtrak says commuters could encounter delays between New York City and Philadelphia due to the hot weather.

The rail line said Friday that heat restrictions have been put into place.

According to Amtrak's website, a heat restriction means locomotive engineers must operate at slower speeds than normal.

That's because the rails and wires could expand when they get too hot.

"Speed reductions are based on the rail temperature, not the ambient (air) temperature," Amtrak's website reads. "That data ensures we're only issuing heat restrictions when necessary."

Amtrak recommends that commuters check online service alerts or call/text 1-800-USA-RAIL (1-800-872-7245) for updates.
