The present invention relates to a two-level railway vehicle car of the type comprising:

• a passenger compartment having a lower floor and an upper floor;
• two end bogies over which the passenger compartment has first and second intermediate platforms;
• two access doors to the passenger compartment whose thresholds open on a first and a second access landing are at a height between the lower floor and the corresponding intermediate platform, the car comprising:
  • in the vicinity of the first access door:
    • an ascending passage of the first access stage to the first intermediate platform;
    • a passage from the first access floor to the lower floor;
    • a direct ascending passage from the first intermediate platform to the upper floor;

Such a car is well known by the document DE-U-9,421,209 .

Rail transport operators seek to optimize the performance of their network, in terms of the number of passengers transported per unit of time and per line. For this purpose, they use two-level vehicles comprising in each car a lower floor and an upper floor forming two superimposed levels on which the passengers can take place.

To reach the target, it is important for the operators to improve the speed and speed of the trains on the tracks, the number of passengers in each train, as well as the time of immobilization in station allowing the rise and the descent. passengers of the train.

While the pace and speed of the train are relatively independent of the other parameters, the number of passengers in each car and the station downtime to allow the ascent and descent of the passengers are interdependent. It is therefore necessary to obtain a satisfactory compromise between the number of passengers per train and the station downtime. Indeed, the greater the number of passengers in a train, the more space available for access and movement of people in the train is low, which increases the downtime station.

It is therefore necessary to define a compromise between the constraints related to the number of passengers transported and those related to downtime.

Rail vehicle cars are known which, in order to optimize the number of passengers in each car, provide for the access doors to be arranged at the ends of the car above the bogies so as to obtain a central part of the longest car. possible.

This long central part of the car can accommodate a large number of seated passengers. However, since the access doors are located above the bogies, this arrangement requires that the passengers take one or more steps to reach the access door, which increases the downtime of the train station.

Other trains have low access located at the same level as the wharf, the access doors and the access landings that extend them are then planned away from the bogies. An intermediate platform is provided above each bogie to accommodate passengers. A first stairway is then provided between the access landing and the intermediate platform and a second staircase is provided between the intermediate platform and the upper floor. Thus, to access the upper floor, a passenger must take two stairs successively so that access is only indirect, reducing again the downtime of the vehicle station.

Other arrangements have been contemplated, allowing direct access from the access door to the upper floor and the lower floor. However, the presence of these direct accesses which limits downtime considerably reduces the number of passengers that can be transported.

Finally, each vehicle must have a certain number of technical equipment necessary for motorization and braking, such as transformers, converters or air conditioning equipment, which also contribute to reducing the space available for transporting passengers.

Thus, the solutions known until now poorly meet the two constraints of a large number of passengers and a reduced downtime.

The object of the invention is to propose a railway vehicle car architecture leading to a large number of passengers and a reduced downtime.

For this purpose, the subject of the invention is a two-level rail vehicle car according to claim 1.

• le passage entre le deuxième palier d'accès et le plancher inférieur est un passage descendant du deuxième palier d'accès au plancher inférieur ;
• le passage descendant du deuxième palier d'accès du plancher inférieur comporte une rampe inclinée depuis le deuxième palier d'accès vers le plancher inférieur ;
• la première porte d'accès est disposée au-dessous du plancher supérieur ;

• the car comprises at least one auxiliary transformer disposed in the recess, on the roof;
• the thresholds of the first and second access doors are disposed at a level of between 500 mm and 800 mm with respect to the running surface of the car; and
• the first intermediate platform has no seats; and
• the second intermediate platform is equipped with seats.

The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the single figure which is a schematic longitudinal sectional view of a rail vehicle car according to the invention.

The vehicle car 10 illustrated in the single figure is a passenger car adapted to be integrated into a railway vehicle constituting a train or a train comprising a succession of such cars.

The car has a length between 14 m and 28 m.

The car has a rigid non-articulated body defining a passenger compartment 12 extending along its entire length and having in the middle part a lower floor 14 and an upper floor 16, both provided with seats 18 for the comfort of passengers. The upper floor 16 extends over its entire surface above the lower floor 14.

At each end, the car has a bogie 20, 22 hinged under the body.

Above each bogie, the passenger compartment 12 has an intermediate platform 24, 26, disposed respectively above the bogies 20 and 22. The platform 26 is equipped with seats 18 while the platform 24 is without, the latter serving as a passage area for passenger access to and from the upper floor 16.

At each end, in its transverse wall, the car has passages 28, 30, allowing communication with adjacent cars.

Thus, preferably, the platforms 24 and 26 are arranged at the same level.

The difference in height between the upper floor 16 and the intermediate platforms 24, 26 is preferably between 1000 mm and 1500 mm.

In its side wall, the car has two access doors 32, 34 disposed near the ends of the car but being offset longitudinally towards the central section of the car relative to the bogies 20, 22.

The doors 32, 34 have a threshold 36, 38 disposed in the lower position, that is to say at a height less than the intermediate platform 26 and greater than or equal to the height of the lower floor 14.

The position of the thresholds 36 and 38 is preferably included in the height of the wheels of the car. Thus, more particularly the height of the thresholds is between 500 mm and 800 mm with respect to the running surface of the car.

Each access door 32, 34 serves an access bearing 42, 44 located at the threshold 36, 38.

The lower floor 14 extends between the access bearings 42 and 44, the access bearings 42, 44 separating longitudinally the lower floor 14 from the intermediate platforms 24, 26 respectively

The access door 32 and the associated bearing 42 are disposed below the upper floor 16.

The access landing 42 extends in the plane of the lower floor 14, and serves a seat access corridor 18 of the lower floor 14, or slightly above, a ramp or a descending staircase 45 serving the floor lower 14 from the access landing 42.

Optionally, a downward ramp is provided between the access bearing 42 and the lower floor 14.

The access bearing 42 is connected to the intermediate platform 24 by a direct passage 46 ascending the landing to the platform having a staircase formed of a reduced number of steps equal for example to two or three.

The difference in height between the lower floor 14 and the intermediate platforms 24, 26 is between 40 and 60 cm.

A second direct ascending passage 48 connects the intermediate platform 24 to the end of the upper floor 16.

This upward passage from the platform to the upper floor has a staircase with a number of steps between 4 and 10.

Thus, the access bearing 42 directly serves the lower floor 14 and the intermediate platform 24 and indirectly, the upper floor 16 via the intermediate platform 24.

A recess 50 is provided in the roof of the car above the compartment 12. This recess extends only above the intermediate platform 24 and partially above the ascending passage 48 but stops above the upper floor 16. Equipment specific to the operation of the vehicle is installed in this recess.

At the other end, the access landing 14 serves the corridor of the lower floor 14, either directly, the latter being at the same level, or by a ramp or a descending staircase 54 having a difference in elevation between 100 and 500 mm.

The access bearing 44 is connected to the intermediate platform 26 by a direct upward passage 56 formed of a staircase comprising two to three steps and rising from the access landing 44 to the intermediate platform 26.

In addition, a direct access ascending passage 58 is provided between the access bearing 44 and the end of the upper floor 16.

Thus, the access bearing 44 directly serves the lower floor 14, the intermediate platform 26 and the upper floor 16.

Recesses 62 are provided on the roof above the compartment 12.

These are placed above the intermediate platform 26, the ascending access passage 56, the access bearing 44 and partially above the direct ascending access passage 58.

However, these recesses 62 are absent above the upper floor 16.

Train equipment such as main transformers, converters, or air conditioning equipment are installed in recesses outside compartment 12.

It is understood that such an arrangement of the car, in which both ends are equipped with access serving areas of the car following direct or indirect differentiated access, optimizes both access to the car and the number of passengers carried.

Indeed, the nature of the passages at the level of access 32 promotes the space to receive passengers, indirect access to the upper floor to reduce the areas dedicated to stairs and to increase the number of seats, including above the access landing 42.

Access 34, providing direct access passages to each of the areas of the compartment, namely the lower floor 14, the intermediate platform 26 and the upper floor 16 reduces the downtime of the vehicle for the rise and fall. descent of travelers.

In addition, the arrangement of this end of the car allows the existence of recesses 62 of large size in which are installed comfort and operating equipment of the vehicle such as auxiliary transformers or air conditioning equipment. Thus, these equipment do not have to be placed directly in the compartment, to reserve it to passengers. In particular, the other end of the car is devoid of equipment, to free up space for passengers.
