7 celebrity trailers destroyed for Macy’s Thanksgiving Day Parade in NJ inferno

A fast-moving fire destroyed seven buses and trailers set to be used by celebrity performers at Macy’s Thanksgiving Day parade – with investigators saying Monday morning’s inferno may have been “man-made,” according to a representative for the owner.

The fire tore through the Royal Buses facility on the Lincoln Highway in South Kearny around 6am, the company’s booking agent Chrisel Flores told The Post.

The luxury trailers, with interiors designed by the company, would be used by performers like Mariah Carey, her collaborators and dancers, Flores said. The Rockettes also use the units, she said.

“Everyone was unique and that was pretty devastating,” Flores said. “Those were the seven units that we have already built in the last two years.”

But all is not lost — there are “replenishment units” at the company’s other locations, including in Brooklyn and Parsippany, she said. The Kearny facility is the headquarters.

A groundsman heard a “big bang” before spotting the fire, Flores said.

Three buses were engulfed before the flames spread like a “domino effect” to the other four, she said.

Local police say foul play may have been involved and suspect the fire was “man-made,” according to Flores.

Other factors — including electrical or weather issues — have not been officially ruled out.

Kearny Police and Fire Department did not immediately respond to calls from The Post Monday.

The facility has seen its share of burglaries in the past — with suspects stealing RV batteries, Flores said.

But “our area hasn’t been devastated for a year,” Flores said.

Security cameras are installed but there were no alarms at the time of the fire.

“We’ve been in business for over 20 years,” she added. “We go through the entire protocol to make sure everything is secure. Nothing like this has happened in over 20 years.”
