Some MI 84 commuter rail stock trains to be re-assigned…

I heard from the Symbioz forums a few days ago that the STIF is proposing to re-deploy twenty trainsets of the MI 84, the commuter rail rolling stock that is gradually being phased out from the RER Line A. This latest development appeared in a media release from the STIF dated February 13, 2013. The release is in French, so you will need a translating service to translate the document into your native language.

Until new rolling stock is ordered to replenish the aging fleet of trains along the RER Line D and Suburban Rail Line R, the STIF is proposing the use of outgoing MI 81 rolling stock to reinforce a portion of both lines for the meantime. The sections that would utilize the MI 81 include the Melun/Juvisy segment of the RER Line D and the Melun/Montereau branch of Suburban Rail Line R. The MI 81 stock along the RER Line A is currently being replaced with the new MI 09 stock, which was introduced in 2011.

Some in Paris may wonder why the MI 81 is being replaced before its predecessor, the MS 61. My understanding is that the MI 81, though similar to its counterpart on the RER Line B, the MI 79, the MI 81 was constructed in a cheaper manner than the MI 79, resulting in greater wear and tear. As a result of this, none of the MI 81 stock have been heavily refurbished, unlike the MS 61. However, it seems that the STIF can put some of the MI 81 trains to good use for a few more years because they will not need extensive refurbishment to run on the other lines, probably just some minor aesthetic and mechanical improvements.

In addition to the possible movement of the MI 81 stock to the RER Line D and Suburban Rail Line R, the STIF is also proposing to bring forth 12 Z2N commuter rail trains to the northern portion of the RER Line D to strengthen service. These trains would be transferred from Suburban Rail Line P, which is currently getting the brand new Z 50000 series rolling stock (known also as the Francilien).

Paris RER E Extension Approved

Happy February everyone!

For those of you who reside in Paris, I have some wonderful news to report! The planned extension of the commuter rail line E has been approved, making way for a possible start of construction date in 2014!

Note: I’ve obtained some the information used for this blog post from the International Railway Journal article, Paris RER Line E extension approved. I’ve provided a formal citation at the end of this post using the MLA format (via Citation Machine). The remaining parts of this post uses info from Symbioz, which is in French.

For those of you who may be unfamiliar with Parisian transports, Line E is part of the RER Commuter Rail network in Paris, France. RER stands for Réseau Express Régional, or Regional Express Rail. Much of the system was built in segments during the 1970s, 80s, and 90s, with some segments utilizing former passenger rail lines that were established long ago (such as the Ligne de Sceaux, which is a part of the RER Line B today). Line E opened to passengers in 1999 and is the fifth line to be constructed in the RER system. The line was originally known as project EOLE (which meant Est Ouest Liaison Express) during its planning and construction [1][2].

The current route connects Gare St. Lazare and Gare du Nord (via station Magenta, where connections to RER Lines B & D are available) to the western suburbs of Noisy-le-Sec, Chelles-Gournay, Val de Fontenay (where it connects to RER Line A), Villier-sur-Marne, and Tournan (among many others) [1]. The planned extension would bring the RER E to Mantes-la-Jolie via the La Defense district,  partially via the existing infrastructure of SNCF (which is the French National Railway) and one of the branches of the RER A. The other segment of the extension will consist of a new 8km tunnel that would be dug between Gare St. Lazare and La Defense, paralleling it with Line A near station Auber. Once the extension is complete, it is expected that travel time between La Defense and the western suburbs will be reduced by roughly 15 minutes. The extension will also relieve congestion on parts of Lines A & B [3].

With final approval granted for the extension of Line E (which is known as the Declaration of Public Utility), construction is set to begin sometime in 2014, with completion estimated to be sometime in 2020 [3].
