A Southern Rail train being transported on a lorry caused delays for motorists when it became stuck at a crossroads in south east London.
The carriage became wedged as it tried to navigate a tight corner in Crystal Palace on Wednesday night and held up traffic for half an hour, eyewitness Luke Alexander said.
Mr Alexander, who works at a bar opposite the junction, said he had gone outside after hearing a commotion.
I think the truck taking it had taken the wrong route and it had completely jammed itself on top of the crossroads, he said.
Everyone was finding it the most hilarious thing including the truck drivers themselves who were trying to negotiate it through the crossroads.
Mr Alexander described the turning as a pretty tight squeeze and said at one point the carriage, which appeared damaged, was wedged against a traffic light.
The 25-year-old, who lives in Crystal Palace, said it was impossible not to see the complete irony of the situation.
A ban on overtime by drivers on Southern Rail has caused delays and cancellations for commuters, while services were halted for three days last week when members of Aslef went on strike .
But Mr Alexander said onlookers took the delay in good spirit and broke into huge applause when the lorry managed to turn the corner.
