London’s £19bn Elizabeth line has been suspended due to a swan on the tracks, passengers have been told.
People on board a number of services said they were informed the bird was blocking routes at Paddington station on Thursday afternoon.
Transport for London (TfL) said there are severe delays “due to an obstruction on the track”.
There is currently no service between Abbey Wood in south east London and Heathrow Airport in west London.
Taking to social media to voice there frustration, one passenger stuck on the underground line called the situation “a joke”.
Another passenger more optimistically wrote: “So apparently I’m doing my part to help save the life of a swan today…Glad the swan is being taken care of!”
The Elizabeth Line, named after the UK’s longest-serving monarch, opened to passengers on May 24 last year, following a five-year delay.
It stretches from Reading, in Berkshire, and Heathrow Airport, in west London, to Shenfield, in Essex, and Abbey Wood, in south east London.
