The renovation involves both technical modernisation work and the refurbishment of the interior fittings of the trains in order to improve comfort for passengers. The exterior livery is also changing to the colours of Île-de-France Mobilités, which are gradually visible on the new buses, trams, metros, RER and Transiliens for greater coherence across the entire Ile-de-France network.
The new layout of the carriages will allow passengers to benefit from a new atmosphere, with more modern colours, improved lighting in the trains, new floor coverings, etc.
