If you thought the rail cars without air conditioning were bad … An adult and four kids got stuck on a Metro elevator Monday for 40 minutes at the Cleveland Park station.

The elevator became stuck about 12:35 p.m. and D.C. Fire & EMS crews had to rescue them, said Metro spokeswoman Taryn McNeil. They were freed at 1:05 p.m. and had no reported injuries, she said.

The elevator was taken out of service until it could be repaired, she said.

The lift is a popular one for families heading to the National Zoo, so it often fills up with strollers and tots. Last July, 10 people including four kids were stuck inside the nearby Woodley Park station elevator for an hour and half.

And, no, the elevators do not have air conditioning, Metro officials clarified last week.
