It comes after the announcement that First Group and MTR will be the new owners of the rail franchise from August this year.
There will be 90 new trains on the network with 22,000 extra seats into London Waterloo each morning and 30,000 out of the station each evening during peak times.
The new trains will benefit passengers using the Reading, Windsor and London routes.
Existing trains will be refurbished, boasting new seat covers, improved toilet facilities and charging sockets in the carriages.
