Images online show crammed Tube carriages with people sat in the dark after being stuck underground for hours yesterday (September 1).
Footage has also circulated online showing crowds of people walking through the tunnels of the Jubilee line to make it to the platform of a station.
Transport for London (TfL) said that this was due an incident train and an additional faulty train at Waterloo.
Severe delays have continued on to today (September 2), across the entire line.
When commuters walked through the tunnel yesterday, they were guided by staff as they walked on the tracks.

Engineers are working as quickly as possible to restore a good service on the line.”
