Power line damage delays trains between London and East
Train services in and out of Liverpool Street station in London to destinations across East Anglia have been disrupted by damaged power lines.
Network Rail engineers are working to repair the damage in Bethnal Green.
The damage caused delays of up to an hour and some trains were cancelled.
On Tuesday afternoon Network Rail said five out of six lines that serve Liverpool Street were now open although there are still some delays. A full service is expected on Wednesday.
