Great Western Railway (GWR) has announced it has finalised an agreement with Bombardier and Porterbrook to procure 37 new Class 387 Electrostar EMUs for its Thames Valley route.
GWR said the new four-car units, which will replace the operator’s ‘Turbo’ fleet, could begin to enter service as early as September.
The new units, which add to eight already ordered by GWR, are due to go into service on the Hayes & Harlington – London Paddington route on September 5.
GWR will be able to operate the EMUs either as four, eight or 12-car trains.
Great Western Railway managing director, Mark Hopwood said: “The Thames Valley is one of the most popular rail corridors in the UK.
“We’d already promised the current fleet would be upgraded to provide much needed additional capacity and faster journey times, but this deal goes even further offering the comfort of what will be most up-to-date commuter fleet on the UK rail network.”
