Can you tell me more?
There was also a faulty train at Havant earlier today which blocked the line towards Portsmouth for some time. The line has re-opened but services may still face delays, cancellations or alterations.
Network Rail will need to attend the train at Swanwick to remove the tree and ensure the safe running of the train. This may take some time and the line towards Southampton will remain blocked until this is completed.
