After roughly 90 minutes, all trapped occupants from an elevator stuck at the Woodley Park/Adams Morgan metro have been freed. A couple with a baby from rural Pennsylvania and another couple were rescued safely by DC Fire & EMS via a pulley system without injury. 👏

How many times can @FirstBusUK disappoint a person?! Yet another #Bristol bus disappearing into the Bermuda Triangle of public transport. Can we get a public transport system that we can rely on please?
