Abstract

The railway vehicle ( 10 ) includes a plurality of cars ( 12, 20 ) articulated to one another, the plurality of cars including:
a single first key car ( 12 ), having a first architecture, a plurality of second cars ( 20 ), having similar second architectures different from the first architecture.

The first key car ( 12 ) has no dining area.

First claim

The invention claimed is:

1. A railway vehicle including a plurality of cars articulated to one another, the plurality of cars comprising:
a single first key car having a first architecture, the first key car configured as the first car placed when assembling the railway vehicle, and mechanically the first car of the vehicle mounted on its bogies,
a plurality of second cars, having second architectures similar to one another and different from the first architecture,
third end cars, having a third architecture different from the first and second architectures, wherein:
the first key car extends in a longitudinal direction between two first ends, the first architecture comprising, at each first end, a first support for one of the plurality of second cars,
each second car extends in a longitudinal direction between two second ends, the second architecture comprising, at one of its second ends, a second support for an additional second car of the plurality of second cars or one of the third end cars, and at the other of its second ends, a connector for connecting to the first or second support of first key car or one of the second cars,
each second car adjacent to the first key car includes, at one of its second ends, a bogie shared with the first key car, and at the other of its second ends, a bogie shared with another second car of the plurality of second cars, each additional second car of the plurality of second cars, includes at least at one end, a bogie shared with one of the second cars of the plurality of second cars,
wherein the railway vehicle comprises a single dining area having a preparation part, in which food and beverages are stored, prepared by a dining service person, and sold, and a dining part, which is a room arranged specifically for dining, including tables and/or seats, and the single dining area is arranged in one of the second cars of the plurality of second cars,
wherein the first support on both ends of the first key car extends below each connector of the respective second car adjacent the first key car such the connector defines a space between the first key car and the respective second car and that a vertical plane extends through the first support, the corresponding connector and between wheels of the shared bogie of the first key car and the respective second car.

2. The railway vehicle according to claim 1 , wherein the first key car includes at least one passenger area.

3. The railway vehicle according to claim 1 , wherein the first key car includes at least one equipment area.

4. The railway vehicle according to claim 2 , wherein the first key car includes at least one equipment area.

5. The railway vehicle according to claim 3 , wherein the equipment area comprises a household refrigerating unit.

6. The railway vehicle according to claim 5 , wherein the equipment area comprises an air conditioning unit.

7. The railway vehicle according to claim 4 , wherein the equipment area comprises a household refrigerating unit.

8. The railway vehicle according to claim 7 , wherein the equipment area comprises an air conditioning unit.

9. The railway vehicle according to claim 3 , wherein the equipment area comprises an air conditioning unit.

10. The railway vehicle according to claim 4 , wherein the equipment area comprises an air conditioning unit.

11. A method for manufacturing a railway vehicle according to claim 1 , comprising:
producing a first key car, having a first architecture, with no dining area, the first key car being the first car of the vehicle to be mounted on its bogies, the first key car extending in a longitudinal direction between two first ends, the first architecture comprising, at each first end, a first support for an adjacent second car,
producing second cars, having second architectures similar to one another and different from the first architecture, only one of these second cars including a dining area, each second car adjacent to the first key car including, at one end, a bogie shared with the first key car, and at another end, a bogie shared with another second car, and each second car extending in a longitudinal direction between two second ends, the second architecture comprising, at one of its second ends, a second support for another adjacent second car or a third end car, and at the other of its second ends, a connector for connecting to the first or second support of the adjacent first key car or second car,
producing third end cars, each having a third architecture different from the first and second architectures, with no dining area,
placing the first key car,
connecting the first key car with two of the second cars, respectively on either side of this first key car,
adding a plurality of other second cars, each connected to another second car, and
adding the third end cars.
