A £100 million project to refurbish over 300 Electrostar trains used across the Govia Thameslink (GTR) network has been completed.
The project, which took five years to finish, is thought to be the largest fleet upgrade in modern times.
The work was carried out in-house by GTR staff at the Selhurst depot, making it unusual in that no third-party refurbishment company was involved.
GTR runs trains under the Thameslink, Great Northern, Southern, and Gatwick Express names.
No single train was sent off-site for refurbishment.
