RER D, Branches around Corbeil.
Deliveries of 19 new Bombardier Regio 2N trains have been completed at the end of 2019. They are deployed on 2 RER D routes through Corbeil-Essonnes along the Seine valley:
- Juvisy - Ris-Orangis - Corbeil - Melun (the valley route)
- Juvisy - Ris Orangis - Corbeil - Malesherbes
The new Bombardier trains replace Z 20500 units which will be transferred to RER C.
Passengers on the Malesherbes line to/from Paris and the north have to change at Juvisy or Viry-Chatillon in an unpopular modification ( in December 2018 ) that suppressed through trains to Gare de Lyon and the north. This was designed to make the network more robust. It is not known how successful that has been.
Transilien Line N
Line N runs from Paris Montparnasse to Versailles Chantiers. There are 3 branches thereafter, to Ramboulliet, Dreux and Mantes-la-Jolie. 73 Regio 2N sets are on order for delivery to Line N and they will gradually replace the trains of BB 27300 + double deck coaches ( VB 2N ).
The first Regio 2N for line N entered service on January 20th.
Gare de Paris-Saint-Lazare
New Bombardier Z 50000 emu's ( "Francilien" ) are being delivered at a rate of 3 - 4 a month in the 7 coach version for the Saint-Lazare network. A total of 127 sets have been delivered out of 194 ordered.
They have replaced nearly all the stainless steel Z 6400 emu's (originally a class of 75 units). Those were delivered in 1976 and 1978/79. At present, only 27 or 28 Z 6400 units remain on the books and most are apparently held in reserve and have no regular schedules. Some observers speculate that all the remaining Z 6400 units will be withdrawn in March 2019, but there is no official announcement to confirm or deny that rumour.

The station is 70 km from Paris Gare de Lyon and is the last stop in Ile de France on this line. The terminus at Malesherbes is 6 km after Boigneville.
