Cancellations to services between Fareham and Southampton Central Due to signalling problems between Fareham and Southampton Central trains have to run at reduced speed on the line.
Impact:
Train services running through these stations may be cancelled, delayed or diverted between Romsey and Fareham. Southampton Central will not be served. Disruption is expected until 08:00 29/12.
Customer Advice:
South West Trains will accept valid First Great Western tickets between Eastleigh and Southampton Central until further notice.

Looks line everything diverted via Eastleigh, with SWT^▸ (South West Trains)'s "Romsey 6" service withdrawn (between Eastleigh and Salisbury at least) and the Cardiff Portsmouth picking up the stops. A typical expansion:

07:30 Cardiff Central to Portsmouth Harbour due 10:52
This train will be delayed between Romsey and Fareham and is expected to be 4 minutes late.
This train will be diverted between Romsey and Fareham.
This train will call additionally at Dean, Mottisfont & Dunbridge, Chandlers Ford and Eastleigh.
This train will no longer call at Southampton Central.
This is due to signalling problems.

Nice to see FGW^▸ (First Great Western) trains calling at FGW stations.    Stations served by SWT^▸ (South West Trains) but managed by FGW due to the train service patterns changing and the SWT Romsey shuttle taking over.
