Twenty people were rescued from a gondola stuck on a New Mexico streetcar while an employee got stuck on another gondola, the The Bernalillo County Fire Department said. Moisture and winds caused the streetcar to freeze, causing two streetcar cars to stall around 2 a.m. on Saturday, Sandia Peak Tramway general manager Michael Donovan told CBS Albuquerque, New Mexico, subsidiary. KQRE.

People have been rescued from the tourist attraction, which offers stunning views of Albuquerque 2-4 at a time, said Jayme Fuller of the Bernalillo County Sheriff’s Office. Sandia Peak posted on Facebook that she was “working closely” with search and rescue.

Donovan told KQRE that those trapped included tram workers, as well as the Ten 3 restaurant at the top. He said the trams were supplied with food and water, as well as emergency electric blankets.

Some of the riders posted videos and photos of the ice conditions on the tram.

The Bernalillo County Sheriff’s Office is broadcasting a live feed of the rescue on its Facebook page. Support from BSCO Metro Air, the Bernalillo County Fire Department, and New Mexico State Police Search and Rescue are also assisting in the rescue.
