The Central Line has been disrupted due to a trespasser on the tracks earlier this morning.
Trains were initially halted between Liverpool Street and Hainault but have since resumed.
However, this has led to a knock on of delays across the service.
These were branded severe early, though now a representative of the Central Line has said there are minor delays.
Photos on social media showed cramped platforms as commuters complained about the issues.
A statement on Twitter said: "We're now operating with minor delays to all destinations. Tickets are being accepted on local bus services."
An earlier post said: "We currently have severe delays while we deal with a trespasser on the track at Leyton."
One commuter on social media commented on there being an eight minute wait between trains at peak time.
There were also issues on the District Line, with severe disruption between Turnham Green and Richmond due to a signal failure at Gunnersbury.
