The design used for the rehabilitation and rejuvenation of the fleet was conducted by two outside agencies under contracts awarded in October 2000. "RCP Design Global" provided exterior design and interior signage, and "Avant Première" the interior. All vehicles received a new blue and gray Transilien livery with panels of color to highlight doors and internal characteristics. Everything was treated with a graffiti- resistant coating to reduce the impact of vandalism. The trains are equipped with a new ergonomic design of seating, with individual seats instead of the traditional banks. They are covered with vandal-resistant fabric in blue, yellow and red. Circulation and inter-car doors have been modified to improve the distribution of passengers in trains
