Rolling stock
The Transilien R line is operated by Z 5600, Z 20500 and Regio 2N trains. The rolling stock of the line is shared with that of the RER line D.
Since December 8, 2017, forty-eight Regio 2N trainsets have been progressively delivered to enable the redeployment of twenty-four Z 2N double-deck trainsets on the network's other lines, as well as the deletion of the stainless steel Z 5300 trainsets. The Syndicat des transports d'Île-de-France (STIF) decided to acquire them, during the Board of Directors meeting of December 11, 2013, so that they would completely renew the current fleet.
The Regio 2N trains will be 110 m long, double-decker, with 582 seats per train. At peak times, they will run in multiples of three units, offering 1,746 seats and a total of 3,120 per train, for a total length of 330 m. These trains will offer passengers a maximum number of seats, given the long journey times of up to 1.5 hours (including half an hour without a stop between Paris and Melun). On the other hand, unlike the TER versions, the Transilien fleet will have no toilets, which has provoked strong reactions from regular users of the line.
The total investment amounts to more than 900 million euros, including the order for 43 Francilien trains for the H, K and L lines of the Transilien network. It is financed in equal parts by STIF and SNCF under the STIF/SNCF contract. The first 42 units were ordered in December 2014 at a cost of €397 million, with delivery of the first elements scheduled for September 2017 and full equipment of the line by the end of 2018
