Commuters using South West Trains stations are set to benefit from double the current service on the Hounslow Loop from December 13.

The new timetable will be introduced in mid-December providing passengers in Hounslow with extra services during the busy morning, evening and weekend periods and more seats with longer trains on Saturdays.

The improvements will result in 57,000 extra seats for passengers using stations such as Feltham, Twickenham , Whitton and Hounslow.

Tim Shoveller, Managing Director for South West Trains, said: “Our improved timetable provides more than 57,000 additional seats for passengers right across the network and will make a real difference to passengers using stations such as Reading, Hounslow, Ascot, Windsor & Eton Riverside and many more.

“In addition to the extra weekday services, we are providing a significant increase in our capacity at weekends, providing more seats and more services to many of our most popular destinations."

He added: “Alongside the extra services we are continuing the £65m roll out of 108 additional and refurbished carriages which is allowing us to run longer trains on many of our busiest services.”

The changes are in light of feedback from passengers and includes three new services during peak times.

There will be a new weekday morning service at 6.23am from Reading to Waterloo which passes through Feltham, Twickenham and Richmond; an additional 8.27am Hounslow to Waterloo service calling at Whitton, Twickenham, Richmond, Putney and so on; as well as a new 7.35pm service from Waterloo to Reading.

On Saturdays there will be longer trains on the Waterloo to Waterloo via Hounslow route and on services between Waterloo & Weybridge with certain services such as the 8.03am increased from four carriages to the maximum 10.

There will also be an extra Sunday afternoon and evening services, doubling the current service on the ‘Hounslow Loop’.

The full £65m roll out of South West Trains’ 108 additional and refurbished carriages will be complete in early 2016 complete with wider doors, improved seating, full CCTV and new flooring.

South West Trains also continues to work with Network Rail and other partners to deliver improvements across the network including the overhaul at London Waterloo station.
