As if travelling on public transport isn't stressful enough, this surveillance video captures the moment a bewildered young boy is separated from his father by a faulty train.
As three-year-old Aiden jumps off the train holding his father's hand, the doors immediately begin to shut, leaving the young boy alone on the platform.
The incident happened at 8.15am on Monday in Portland. Luckily the platform wasn't crowded when Aaron Bailey desperately tried to open the carriage door in a futile bid to reach his stranded son.
Thankfully, a kindly commuter witnessed the train door malfunctioning and stayed behind to look after the young lad until his father was able to return, seven minutes later.
Watch the video to see the pair reuniting after what must have been a very stressful way to start a Monday morning. Possibly don't watch if you're pregnant however. I'm still wiping away the tears.
Meanwhile, the train company, TriMet, have got some explaining to do. They don't seem to know why the doors closed on Aaron's hand - or why the emergency stop button didn't work.
