NEW YORK — Commuters into and out of New York’s famed Grand Central Terminal faced crippling delays Wednesday, a day after a raging fire broke out beneath elevated train tracks in the city, officials said.

The blaze Tuesday night at a garden center underneath Metro-North tracks, north of the station in Manhattan’s East Harlem section, halted train service and left thousands of commuters stranded on their way home.

Metro-North said two of the four tracks in the area of the fire were operational for Wednesday’s morning rush. Trains were slowed from their normal 60 mph to 30 mph as repairs continue.

The fire caused damage to a center column beneath the elevated tracks.

“You can see the damaged column in the center. We have to take the load off that structure … and transfer it to other places so that the center beam can be supported so the two inside tracks can go back into service,” MTA Chairman and CEO Thomas Prendergast told WNYW’s “Good Day New York” on Wednesday morning.
