Nancy Guided Light Transit

The trolleybus Nancy, also called Tramway de Nancy, has been founded in 1982 trolleybus operation in the French town of Nancy and the three neighboring communities Essey- lès -Nancy, Saint-Max and Vandoeuvre -lès -Nancy. In 2001 he was converted to sections track-guided operation, which is why he is now known as Tramway sur pneumatiques. This is the French term for a trolley on pneumatic tires, which is held at least on sections by means of a centrally recessed in the roadway guardrail on track. Responsible transport companies, the Company is Service de transport de l' agglomà nancéienne ( STAN), it operates in the Greater Nancy also various bus lines.

The only in-service T1 line (T stands for Tramway ) has a length of 11.1 kilometers and is served on weekdays in five- minute intervals. The diameter line runs roughly from northeast to southwest. A total of 28 stations are approached, the average distance between stops is thus 411 meters. 2005, 5.8 million passengers were transported.

History

Duo - bus

The trolleybus Nancy was opened on 27 September 1982, the full conversion of the 18 -kilometer route 19 (now the North section line 2/BHNS ) by Champ Le Boeuf in the suburb Laxou to Ile de Corse on Duo - bus operation took place in the city center eventually November 25 of the same year instead. It was followed by the commissioning of the 21-kilometer line 4 ( northern branch today partially line 5, now largely southern branch line T1) of Vandoeuvre CHU Brabois by Beauregard on 20 December 1982, and in 1983 the 14 -kilometer line 3 of Laxou Provinces by Essey- lès -Nancy ( Westast now part of Line 3, Ostast today T1 line ). The Duo- bus mode is set to track-guided operation on 1 August 1999 due to the impending change, some of the buses was initially continue to be used in pure diesel mode.

Conversion to rail-guided operation

On 8 December 2000, the new system was inaugurated, the official reopening of the trolleybus Nancy should take place on January 2, 2001. Due to technical problems the start of passenger traffic has been postponed to 11 February 2001. Only the sections of Vandoeuvre CHU Brabois to Jean Jaurès and Nancy Gare to Essey Mouzimpré were retained. The remaining network is operated with diesel and natural gas buses, the driving lines are partially but still present.

The vehicles of the type Bombardier TVR represent a blend of trolleybus and tram dar. Worldwide is the only system in Nancy and - in modified form - in Caen in use. Driving is on conventional rubber wheels. The tracking is performed on approximately three -fifths of the distance over a centrally located guide rail, otherwise regardless of the road space.

The TVR system with bipolar overhead line was preferred to a conventional tram for several reasons:

• Some of the existing infrastructure for the trolley buses (sections of lines 3 and 4) could be used
• Mixed operation between conventional trolleybus and TVR would have been possible
• Due to the higher friction a rubber-tired vehicle for the steep section between Callot and Vandoeuvre CHU Brabois appeared (up 13 percent) more appropriate than a tram
• In the eastern suburbs of Saint-Max and Essey- lès -Nancy separate routes were not allowed
• The system appeared cheaper than a tram
• Nancy was the first commercial introduction of a Tramway sur pneumatiques to pioneer a new technology

The tracking is on the central region, the two turning loops at the end points and - limited a short section in Essey - just out of town. At the beginning of the rails, but also in the course of which, there are Einfädelstellen where the guide rollers are lowered in a short time the vehicle is stationary ( dropage ). Even the drawing of the rollers ( dédropage ) happens during a brief halt outside the stops.

On the steep section between the stations Callot and Vandoeuvre CHU Brabois and between stops Gérard Barrois and Essey Roosevelt ( out of town) or Essey Mouzimpré ( town) there is no guardrail. On these routes, the vehicles steered manually like conventional trolleybuses. For this reason, they have a road approval and accordingly have a motor vehicle license plate.

A two-pole overhead line provides the power supply, the rod current collector are similar to those of ordinary trolleybuses. In addition, the cars have a diesel-electric auxiliary drive. He is in diversions ( for example because of construction or traffic accidents ) and in trips to and from more than two kilometers away custodian required, whereas no top line leads.

In the early days, the new system had to contend with great technical difficulties. In the narrow S-curve at the station and at other locations " derailed " vehicles, which had two accidents involving injuries result. This meant that the operation of the TVR, was once more in the long term interrupted by six shorter breaks within two months, from mid-March 2001 to 12 March 2002 in order to conduct a thorough ENHANCE. Meanwhile, the traffic runs relatively smoothly.

Rolling stock

At times the duo -bus operation were 48 joint type cars Renault PER 180 H available, they carried the running numbers 603 to 650

Denotes the three-part double articulated vehicles used today, due to the focus on the French market as TVR (Transport sur ​​Voie Réservée ), were supplied by Bombardier Transportation. A total of 25 units are in use, they are numbered from 1 through 25.

View

While it was decided in Caen, close down the track trolleybus system in 2016 and to build a conventional tram on the same route until 2018, the TVR is repaired in Nancy for another ten years. Since Bombardier future offers no more TVR, Nancy will be the only city with this system from 2016, but that can not be further expanded. The 2013 as the "Bus à Haut de service level ( BHNS ) " introduced new high-speed line 2 is therefore operated with special gas - articulated buses, a high proportion of their own lanes and priority control at traffic lights.
