The Tyne and Wear Metro, which serves Sunderland and Newcastle, apologized to customers for the disruption which they blamed on a “public hygiene issue”.
The passenger is understood to have covered three train seats in feces on Saturday. This meant that the train had to be taken back to the depot to be cleaned.
The cause of the delay was revealed after a passenger complained on Twitter about the disruption on the line linking South Hylton and Airport stations.
In a now-deleted tweet the operator replied: “Sorry, the train has been traveling up from Sunderland with only the rear car in operation as someone has defecated on the train and has covered three seats with feces.
“The train has to go into the depot to be cleaned up. Sorry for the inconvenience.”
Dozens of people reacted with shock and disgust at the tweet, with one Twitter user saying: “What is wrong with people?”
Another said: “That’s Sunderland for you.”
One Twitter user joked: “God I love the north-east.”
A spokesman for Nexus, the executive body that runs the Metro, said: “I can confirm that a train was withdrawn from service due to a public hygiene issue in one of the carriages.
“The train was immediately taken back to our depot to be cleaned.
“Incidents like this are rare on the Tyne and Wear Metro but when they do occur the comfort and safety of our customers is our top priority.”
Unfortunate passengers on board a Great Western Railways service from London to Devon had to continue their journey after a dog with ‘explosive diarrhea’ did his business on the floor.
One such unfortunate passenger was Florence Beasley, who wrote a letter to the train operator in which she said: “Within 20 minutes of departing a dog had explosive diarrhea in the aisle. The train was full and there was no staff in sight.
“The owner stayed at the scene to try and warn people not to step in it.
“After five minutes of me knocking on the staff door, as the cafe was closed, someone finally answered and didn’t attempt to give anything to clean up or cover with.
“He said he’d be up in a minute to check the situation. Seventy-five minutes later, when we got into Bristol, the train staff appeared and said there was no staff to clean it up.
“It is utterly appalling that we were made to endure these conditions and ignored by train staff.”
