– South West Trains
Following a severe incident at Wimbledon this morning, it was necessary to significantly reduce the number of trains through Wimbledon while this incident was ongoing.
Trains and crew that were scheduled to work on trains around our network were not able to get on to these trains due to the disruption. This has had a further impact on our service recovery and spread the problem from our Suburban services to our Windsor services (Waterloo to Staines).
We have reinstated trains on each line of route with the exception of London Waterloo to Salisbury trains which will continue to start from Basingstoke in both directions until 1720.The 1720 London Waterloo - Exeter St Davids departure will be the first service to run its booked route.
Whilst we work to introduce services back into normal operation, customers may see further last minute alterations. Please check before you travel.
Disruption to all services on the South West Trains network can be expected until the end of service today.
Alternative travel options:Passengers may use First Capital Connect, First Great Western, Southern, London Buses, London Underground and London Trams services on all reasonable routes.
There is disruption on South West Trains services this morning between Guildford and London Waterloo due to a signalling problem between Egham and Surbiton.
Engineers are on their way to resolve the problem that means that London-bound services are unable to pass through the area.
It is not known when the problems will be resolved.
South West Trains are warning about cancellations and delays for services between Twickenham and Clapham Junction, between Feltham and Clapham Junction and between Twickenham and Hounslow due to over running engineering works between Barnes and Clapham Junction.
Waterloo to Reading services will run to Clapham Junction and be diverted via Kingston to Twickenham, with other services subject to diversions and alteration.
Tickets are being accepted on First Great Western, London buses, Underground and Overground.
The disruption expected to last until 07:00.
UPDATE - Alton and Camberley line - Developments overnight mean the service on this route will be altered from that previously published.
UPDATE: Buses replace trains Alton to Farnborough and Guildford to Ascot via Aldershot. Mobile link with details: http://t.co/Plffrffe4p

Police are investigating an incident in which a person was hit by a train at Guildford Station at around 11.40pm on Saturday 30 March.
Our immediate thoughts are for the family of the person involved. We are providing information to assist police with their inquiries into the circumstances of the incident.
As a result of the incident, Guildford Station was closed to allow police to complete their investigation.
However, the station re-opened at 8.15am yesterday (Sunday 31 March) and services returned to normal.
As thousands head off for the Easter weekend, commuters who travel through Reading are being warned of disruption as the station is closed due to £900m upgrade.
There are no direct services from Swindon, Oxford and Newbury to London. Trains from Bournemouth and Southampton to the north will also be affected. Here's our Transport Correspondent Mike Pearse.
First Great Western Managing Director Mark Hopwood explains in detail the changes to services and why the work is needed. He spoke to our Transport Correspondent Mike Pearse.
We have been treating the third rail in the south of England with anti-icing solution and trains were running around the network overnight to keep the rails clear of ice as much as possible.
Additional people were used on the ground to respond to incidents and carry out regular inspections of the infrastructure.
We will continue to work closely with train operators throughout today to deliver the best possible level of service and apologise for any disruption caused to passengers.
For the latest information, passengers should check with National Rail Enquiries or their train operator before travelling.
Services on parts of our network are being disrupted this morning as a result of adverse weather conditions which have also affected other train operators.
Cold weather conditions have caused a build-up of ice on the conductor rail which is used to power our trains.
When ice forms on the conductor rail it affects the power supply to trains and services are prevented from running normally.
As a result there are delays to services across some parts of our network. Services between Havant and Guildford are currently subject to delays of up to 60 minutes.
Trains between Waterloo and Reading are currently delayed by up to 30 minutes. Trains operating between Ascot and Guildford may be delayed by up to 40 minutes while services between Farnham and Alton are suspended.
We would like to apologise to customers for the delays to their journeys this morning.
