Subway of Lausanne

M1 line

The underground line M1 was inaugurated the May 24th 1991. It was called in beginning TSOL (Tram of South-west lausannois) and this abbreviation is still largely employed by the users of the line. It is a subway of the light type having only 3 underground stations.

The line, 7,8 km length connects the center of Lausanne, the High Schools (FPSL and UNIL) and Renens.

It belongs to the public Transports of the area lausannoise (TL, in the past Tramways lausannois).

Stations

Line m2

The Métro of Lausanne (m2) is currently in construction, using the layout of the old funicular Lausanne-Ouchy, then a prolongation in new site until Epalinges, intended to cross the agglomeration of the South to North.

Technique

90% of the layout in tunnel, 10% air
automatic Subway tyred with the strongest declivity of Europe.

Characteristics of the line

6 km of Ouchy to Epalinges, including 1,5 km substituent with the current line Lausanne-Ouchy.
14 stations, 1 garage-workshop.
461 meters of average distance enters the stations.
336 meters of unevenness (either an average of 26 meters unevenness between each station).
Food 750V uninterrupted on a side rail of guidance.
5,7% of average slope with points with 12%. The constraints as regards deceleration and braking distance will cause surprising besides that m2 will go more quickly to the rise than to the descent.

Performances

25 million passengers per annum (forecasts)
37.000 served employment.
60 km/h top speed.
18 minutes from one end to another of the line.
To 6.600 people/hour in each direction.
an oar every 3 minutes between the station CF and Sallaz (every 6 minutes on the remainder of the line).

A tyred subway

A tyred subway is able to climb at good speed the slopes lausannoises (12% in certain places; 5,7% on average on the whole of the course). This choice is in addition imperative to have adherence necessary to braking in the descents.

The portions of ways to the free air are heated in winter to ensure a good adherence at the time of bad weather conditions (snow, ice, white frost,…).

Automatic piloting

The subway m2 entirely is automated, managed from a central station of order. What results in less operating costs and which allow a greater flexibility in the event of strong multitude. The quays are equipped with doors of safety and a personnel of accompaniment assists the travellers.

An integral clean line of sight

M2 circulates on a clean line of sight, with double track (except in the tunnel under the station CF due to too high costs), underground on 90% of its layout. Ideal solution with the security issues and of saturation of public transport in urban environment, the subway can develop without interfering on the traffic of surface.

Sure and practical stations

The underground stations are located more close possible surface. They are equipped with staircases, elevators and facilities for the handicapped people. The architects benefitted from the declivity lausannoise to create service roads on several levels, to facilitate the accesses by slopes and to privilege as much as possible the arrival of natural light.

Oars

15 articulated vehicles with 4 bogies motorized.
222 places, including 62 sitted places.
tyred Oar with side guidance based on MP 89 of the Parisian subway.
Entirely automated (Meteor).

Length of the oar: 30,68 m
Length of a car: 15,34 m
Width of a car: 2,45 m
Height of case compared to the way: 3,47 m
Mass of the oar with vacuum: 57.316 kg
Mass of the oar in nominal load (4 p/m ²): 72.856 kg
Width of passage of the access doors: 1,65 m
Height of passage of the access doors: 1,90 m
Power of traction: 4 X 315 kw

Capacity of the oars

Delivery of the oars

The first oar at summer delivered the March 2nd 2006 to Lausanne. Then, all the other oars were delivered to the rate of two per month. On their arrival, the oars were stored with the deposit CF of Lausanne. Then, in autumn 2006, the garage-workshop being finished, the vehicles were moved definitively with the garage of Vennes for a dynamic storage. During the progressive electrification of the finished sections of way, the vhéicules took part in series of tests like with the installation of the final system of control.

The August 23rd 2007, the last section between the stations of Bessières of Ouchy was energized. Consequently, the tests can be carried out on the whole of the course.

Accidents

The February 23rd 2005, part of the vault of the tunnel in building site crumbles under the place the St. Lawrence in full center of Lausanne. More than 500 m ³ of materials (water and ground) crumble in the tube, forming an open hole of fifteen meters. The zone then is completely buckled during several days and from measurements of consolidation and geological analysis begin. An important pocket of water had not been located by the surveys. Work will extend over several months. The incident will have fortunately serious consequences, no person was not in the zone of the collapse which strongly damaged part of a shopping mall. Part of the budget had been allocated for such risks and the end of the building site which was planned for end 2008 was not touched.

The October 27th 2006, a workman dies of the continuations of his wounds. It had fallen a few days before on the building site on the level of the entry of CHUV.

Stations

The line m2 is made up of 14 stations new or existing and entirely transformed on the old section of the Lausanne-Ouchy line. The quays are dimensioned to receive an oar of about thirty meters. Automatic doors synchronized with the doors of the trains make safe the quays of all the stations. The originators took care to bring to the level of the quays the most natural light.

Possible extensions

The terminus the Small crosses is designed to allow a possible northern prolongation of the line towards Epalinges-Village, even until the Country cottage-with-Gobet.

Lausanne-Ouchy line

The railroad Lausanne-Ouchy (LO) was inaugurated in 1877 pennies the shape of a funicular. In 1959 the first modernization took place transforming it Cog railway under name " métro". On this occasion the station of Flon and that of the station CF were already demolished, replaced by concreted and buried modern equivalents. This line nevertheless was always called " Ficelle" by its users because of his past of funicular and continued to circulate in the open air in a trench of greenery for a good half of its way.

Connected to the installations of Flon, it was by this line which the goods trucks forwarded from the main station to the frank cargo warehouses (in Flon) until the construction of a direct connection between the goods station of Sébeillon and the valley of Flon, in 1954.

The line definitively was closed with circulation on January 22nd, 2006. Rolling stock will be given to the French city of Villard-with-Lans which envisages the construction of a new train with toothed rack to ensure a connection with the Balcony of Villard in 2008.

A service of bus was set up to replace " the String " to the opening of the new subway. This service is called Métrobus (MB) the southern loop consists in connecting of Ouchy to the station and the northern loop consists has to connect the station to Montbenon (which is located just above the district of the flon).
