A spokesman said: "Due to a major signalling failure at London Waterloo, please do not travel on our services this morning.
"The failure of the equipment that routes trains in and out of the station means we cannot use Platforms 1 to 14 at London Waterloo at this time, significantly limiting capacity."
Tickets are being accepted on CrossCountry services between Reading and Bournemouth, Southern services between London Victoria, Portsmouth Harbour and Southampton Central, and Great Western Railway services between Salisbury, Westbury and Weymouth.
SWR also confirmed said that any unused tickets valid for today will be valid for travel tomorrow, Tuesday, July 22.
