Commuters entering London via some southern routes experienced delays this morning, due to an over-running of engineering works at Norwood Junction.
Routes affected included London Overground services between West Croydon and Crystal Palace, and Highbury & Islington and Dalston Junction. The Thameslink service between Brighton and London Bridge is also affected.
According to National Rail, Southern and Thameslink services are running normally again, while only residual delays at Norwood Junction.
A broken down train at City Thameslink also caused delays this morning, between London Blackfriars and St Pancras. Services between the stations are now running normally.
