Île-de-France tramway Line 5

Line T5 was designed with the stated aim of providing superior public transportation services in the northern suburbs of Paris, France, specifically the two neighborhoods of Pierrefitte-sur-Seine and Lochères in Sarcelles, which have been identified as possessing an expanding population during the years running up to the turn of the century.[1] It was built to serve in excess of 86,000 neighbouring residents spread across five different communities, these being Saint-Denis, Pierrefitte-sur-Seine, Sarcelles, Garges-les-Gonesse and Montmagny. Key interchanges include St.Denis Market on the Line T1, Saint-Denis Basilica on Metro line 13 and at Garges-Sarcelles on Réseau Express Régional (RER) Line D.[1]

Notably, Line 5 is unlike any previous tramways in the region in that it was designed to be a rubber-tyred tramway; as such, the completed line holds the distinction of being the first tyre-based tramway to be established in the Île-de-France region.[1] Between 1999 and 2004, planning and surveying of the intended line was performed while the project was quietly defined by planning authorities. During February 2005, the Line 5 project was publicly announced by the Syndicat des Transports (STIF), the transport authority for the IIe-de-France region.[1]

During November 2006, STIF issued its approval of the route's preliminary draft.[1] During the first half of 2007, it was announced that an agreement concerning financing had been signed between the project's major stakeholders. Transit operator RATP became the principal contractor for the Line 5's construction, which included multiple stations and a maintenance depot.[1] The regional councils of Val d’Oise and Seine-Saint-Denis were assigned responsibility for the civil works relating to the highway and associated public spaces. STIF served in a project management capacity on the construction phase, coordinating between the different parties involved.[1]

During January 2008, work commenced upon preliminary construction of Line 5; during this phase, it was necessary to relocate numerous residents, pedestrian footpaths and bus stops along the route ahead of the actual construction activity.[1] This displacement and relocation was supported by a one-off investment of €40.23 million, which was contributed by the regional council of Seine-Saint-Denis. Displacement work stated that same month in Valley d’ Oise; by January 2009, the process had reportedly reached the vicinity of Seine-Saint-Denis.[1]

During the final months of 2009, civil engineering works commenced simultaneously in the Val d’Oise and Seine-Saint-Denis districts.[1] In the latter half of 2010, work began on the construction of the tracks, platforms and the maintenance depot for Line 5. On 29 July 2013, the completed tramway was officially opened for revenue services.[2][1]

Reportedly, Line 5 had been constructed at an estimated cost of €163.13 million.[1] It is both owned and financed by STIF, who hold a 71.5 per stake in Line 5; the remaining minority stakes are owned by the State Region of France (17.2 per cent), the regional council of Val d’Oise (10 per cent) and RAPT (1.3 per cent). RATP is the body responsible for the line's operations, and has invested a total of €52 million on the procurement of its rolling stock.[1][3]
