Railway vehicle having partially standardized carriages
The railway vehicle comprises at least one end car, each arranged at a respective end of the railway vehicle, and, for each end car, a first car adjacent to this end car, and at least one second car, one of which is adjacent to the first car. Each second car comprises a second structural body. Each first car comprises a first structural body substantially identical to the second structural body of each second car, and a structural extension part attached on the first structural body and intended to be connected to the adjacent end car.
1. A railway vehicle extending between two ends, the railway vehicle comprising:
at least one end car, each arranged at a respective end of the railway vehicle,
for each end car, a first car adjacent to this end car, each first car having a first structural frame,
at least one second car, one of which is adjacent to the first car, each second car having a second structural frame
wherein:
each second structural frame is constituted of a second structural body, and
each first structural frame is constituted of a first structural body and a structural extension part, the first structural body being identical to the second structural body of each second car, and the structural extension part being attached on the first structural body and intended to be connected to the adjacent end car,
wherein each first car comprises its own bogie.
2. The railway vehicle according to claim 1 , wherein the structural extension part of each first car is fastened by bolting to the corresponding first structural body.
3. The railway vehicle according to claim 1 , wherein the structural extension part of at least one of the first cars is made from a different material from the corresponding first structural body.
4. The railway vehicle according to claim 1 , wherein each of the first cars and second cars shares a shared bogie with at least one other of the first cars and second cars.
5. The railway vehicle according to claim 1 , wherein the first structural body and the corresponding structural extension part rest on the bogie.
6. The railway vehicle according to claim 1 , wherein the first structural body rests on the bogie, the structural extension part being supported by the first structural body.
7. A manufacturing method for manufacturing a railway vehicle, wherein the method comprises:
producing a plurality of identical structural bodies,
mounting at least one first car with one of the identical structural bodies and a structural extension part attached to this structural body,
mounting at least one second car with another of the identical structural bodies,
providing at least one end car, each arranged at a respective end of the railway vehicle,
for each end car, connecting one of the at least one first car with this end car, the structural extension being connected to this end car,
connecting one of the at least one second car to the first car.
8. The manufacturing method according to claim 7 , wherein the structural extension part of each first car is equipped with components prior to its assembly with the corresponding structural body.
