Following a points failure at Fratton all lines have reopened.

As normal service resumes, trains between Portsmouth Harbour and Havant / Southampton Central may be cancelled, delayed by up to 30 minutes or revised.

Disruption is expected until 08:00.

Southern customer advice:

Southern services that run to / from Portsmouth Harbour and Portsmouth & Southsea will terminate and restart at a different station instead, for instance at Chichester or Bognor Regis.

You'll likely need to change trains in order to complete your journey, or use an alternative route instead.

Tickets will be accepted for no extra cost on the following:

• Southern services on any route including via Brighton
• Thameslink services between Brighton and London
• South Western Railway services between Portsmouth, Clapham Junction and London Waterloo

Can you tell me more about the incident?

A points failure has been reported, and this is preventing trains from using some of the routes through the Fratton area.

Points are moveable sections of track which can send trains onto different routes at junctions. These are part of the signalling system, generally managed by Network Rail.

Points can stop moving correctly for a number of reasons. For example, there may be an obstruction in the moving parts, or the electronic control systems may have developed a fault.

Network Rail will send their specialist Signalling & Telecoms teams to site, and they will set up a safe method of working on the track. To allow staff to access the railway, sometimes train have to stop completely, which can lead to your train being held at stations or signals en route.

As soon as it's safe to go on the line, the staff will diagnose the fault and find any quick solutions to resolve it.

Whilst this is being done, Southern will be monitoring progress closely. At times, replacement parts may be needed, or specialist advice from suppliers, which is why some points failures take longer to resolve than others.
