Servicing and rennovation of TGV materail

Visit of the operations carried out on TGV train tracks (servicing and renovation) and on the Repairable Parts Material (RPM): axles, gear motors, transformers, electronic cards.

Citadis Dualis tram-train, an innovative transport system.

Citadis Dualis answers the growing need of cities to develop public transport between the centre and suburbs, without changing the load, to connect the city centre tramway network to the suburban rail network. The tram-train Dualis penetrates to the heart of cities like a tramway and runs on a regional rail network by adapting power, safety and comfort. This confi guration makes it a polyvalent mode of transport: its tram gauge enables it to circulate in the city, while its train performances enable it to transport passengers at the speed of 100 km/h in the suburbs, without them having to change their mode of transport.

"Visit of the Point Control Centre (PCC), presentation of tools and line".

PCC is a key functioning element of the North Europe TGV line. It plays a dual role: on a daily basis, it applies the traffic transportation plan and manages malfunctions while simultaneously applying regulatory procedures and surveying the quality of transportation and required level of regularity. At night, between 10:30 PM and 5:00 AM, it gives track interception permission to enable maintenance work to be carried out (rails, catenaries, point...).

Visit of the GHH-VALDUNES railway wheel manufacturing shop.

Visit of the production site of Trith Saint-Léger, which manufactures wheels, axles and wheelsets for the railway vehicles. The plant is fed in black wheels by another plant of the group GHH-VALDUNES, the forge in Dunkirk, 150 km away. The black wheels are heat treated, machined, inspected, painted and packaged in Trith. The plant of Trith is also capable of machining axles and of assembling wheelsets. A wheelset is a system composed of an axle, two wheels, and other components like bearings or gear boxes.

Trith Saint Léger plant is the excellence centre for heavy rail vehicles, as opposed to light rail vehicles (like metros or trams). We manufacture here products for high speed trains, EMUs and DMUs, locomotives or coaches. Annually, the site produces 50 to 60000 wheels, 10 to 15 wheelsets, 15 to 20000 axles. We deliver to OEMs like Alstom, Bombardier, Siemens, AnsaldoBreda, Talgo, Hyundai Rotem, etc; and to network operators like SNCF, SNCB, DB, LIRR, RATP, Transwerk, etc.

Visit the training centre for train driving and see its simulators.

May 26th 2011, on the occasion of the World Congress of Railway Research, the SNCF train driving training centre (centre de Production de Formation Traction CPFT) of Lille invites you to show you its facilitates and learn about its work. The Centre will allow you to discover and test its simulators. And its training stall will be on hand to assist and provide you an opportunity to take control of a train.

Crash test on the BOmbardier site Ramp in Crespin.

As France’s largest industrial rail site, Bombardier’s Crespin site houses Centres of Excellence for bogies, reliability and onboard electronics, as well as a COFRAC certifi ed testing laboratory.
The company develops a wide range of rail rolling stock products including the latest new regional/intercity extra capacity double decker train for the Regions, a contract signed in February 2010 with 129 trains ordered to date.
Two other milestone contracts demonstrate Bombardier’s capabilities:
l’Autorail Grande Capacité (AGC) with 700 regional train sets ordered by 21 French Regions, which Hybrid version is a world first ; and the Francilien, co-fi nanced by the French National Railways (SNCF) and Ile-de-France Transport Authority (STIF), a state-of-the-art suburban train which started commercial service in December 2009.

The Railway testing Centre (CEF) is one of the 5 leading dynamic test track platforms in Europe.

While mainly oriented to urban and suburban needs, it also caters locomotive and regional trains needs’ fine tuning test, providing railway constructors and also test performed on-site inside a 110 Kph speed limit, under NOBO process certification.
CEF test platform can anticipate all degraded operation modes for either signalling architecture for driverless metros in urban areas or ERTMS Level 2 architecture for hi-speed railway areas.

CEF’s new twist track test bench, designed for long articulated train,
bring a relevant input for increasing the confidence level in railway operations safety.

As an open structure for operator and constructor needs, CEF is a
constantly evolving dynamic test tool, operated within ISO and IRIS requirements.
