History
In order to complete the rolling stock fleet of line C of the RER, and to eliminate from the line the last 42 Z 5300 elements still in service, SNCF ordered at the end of 1998 year, new trains of type Z 20500, but comprising various changes in motorization and development. These new components were delivered from July 2001 to 2004 and are numbered Z 20900. Their delivery eliminates, by offset, the first sub-series of Z 6100 in the northern suburbs. While the first forty elements are decorated with the three-colorlivery called "Île-de-France", the last fourteen are endowed with the navy blue Transilien livery with cartons, then applied to two-level commuter cars and stainless steel suburban trainsets renovated. The last ten elements of the series are funded by the Île-de-France Regional Council. The OniX traction chain, tested on element Z 20887-20888, is generalized on these new trains. They are distinguished from the Z 20500 by the arrangement of the seats with four front seats, all provided with armrests and whose comfort is improved, by the absence of first class compartment, eliminated in the RER on the 1stSeptember 1999, and by the presence of tinted windows and refrigerated ventilation, making it possible to lower the ambient temperature by 3 to 4 ° C in summer. A locking device for the doors of the power cars allows passengers to gather in the extreme evening in the two central trailers, linked by an interlocking circulation without doors, this in order to lessen the feeling of insecurity in almost empty trainsets.
