UK: Franchised passenger operator South West Trains has invited expressions of interest in separate negotiated contracts to finance and supply between 135 and 250 electric multiple-unit cars to increase capacity on suburban services into London Waterloo.

The operator is seeking EMUs of three to five 20 m cars, suitable for operating in formations of up to 10 cars.

The Department for Transport is expected to approve procurement of the new trains imminently, with entry into service planned to take place between July 2016 and July 2017.

The estimated value of the rolling stock order is between £135m and £425m plus VAT, including two years of maintenance support.
