Commuters faced long delays on Portsmouth-Waterloo trains this morning.
South West Trains said in a statement: ‘Owing to emergency engineering works at Wimbledon trains have to run at reduced speed on some lines. Disruption is expected until 2pm.
‘Following inspections from the engineering team we have been able to raise the speed restriction on the London bound mainline at Wimbledon from 5mph to 10mph.
‘This morning we made significant service reductions in order to minimise the overall impact of the speed restriction and prevent congestion. However, we’ve not been able to avoid impacting the service. The usual speed for trains through the area is 75mph so a reduction to 5mph throughout the morning peak has had a severe impact delaying both mainline ‘nonstop’ and suburban ‘stopping’ trains.
‘Now the speed restriction has been raised to 10mph the impact will be reduced and trains are expected to be up to 5 minutes late running through Wimbledon towards London. As we work to restore the train service across our network there will continue to be alterations to trains travelling to and from London.
‘Please be aware that trains are still running on all routes but you may have to wait for a later service and trains will be very busy throughout the morning.
‘Our engineering teams are on site and monitoring the affected area however it cannot be repaired while we are running trains and will therefore be looked at overnight and through the weekend. Our morning peak service has been badly affected however services through the day are no longer expected to be significantly delayed.
Today’s problems follow lengthy delays in Portsmouth yesterday afternoon after a piece of metal fell onto a track.
