London Underground (LU) in the UK has completed the refurbishment of 106 Northern line trains, as part of a two-year upgrade programme.
French rail firm Alstom partnered with LU for this project. Alstom’s Morden and Golders Green Metro Traincare Centres have replaced 11km of line in the fleet as part of this programme.
In addition, the team has polished 15,688 windows to remove graffiti and changed 27,500 seat backs.
Northern Line Trains performance manager Stevyn Walder said: "Thanks to this refurbishment, Northern line trains are looking better than ever before.
"Customers travelling on the Northern line can now expect a cleaner and more comfortable environment to brighten up their journeys."
This mid-life refurbishing programme saw the replacement of 3.7 million items, which represents approximately 35,000 components a train, Alstom stated.
Alstom Transport UK Urban & Services Managing Director Piers Wood said: "I am sure most passengers didn’t realise what was going on until they got into a refreshed train on their commute to work for the first time."
The Northern line fleet, which was built by Alstom, serves around one million people a day on weekdays and travels around 15 million kilometres a year.
LU recently contracted France-based NFM Technologies to design, manufacture and deliver two tunnel boring machines (TBM) to construct the Northern line extension.
As part of this project, two new stations will be built at Battersea and Nine Elms. They are expected to open in 2020.
