Extra carriages that will add more than 20,000 rush hour seats every morning have been unveiled by South West Trains.
The refurbished trains, which used to run on the Gatwick Express line, will make longer trains on services from Berkshire to Waterloo.
They will use the former Eurostar international terminal at Waterloo - which reopens on Wednesday.
