the low platform having a floor height lower than that of the high floor levels,

the low platform being movable in vertical translation while being maintained horizontally so that a height of the low platform is adjustable in order to allow the height of the low platform to be adapted to a height of a railway vehicle station platform of variable height,

the floor not having steps when the low platform is in a high position,

the low platform being connected to one of the high floor levels by a ramp when the low platform is in the high position and the intermediate platform being connected to the low platform in the high position and to the other one of the high floor levels by other ramps.

2. The railway vehicle carriage according to claim 1 , further comprising a functional space for housing equipment of the railway vehicle, said space being arranged substantially in register with and beneath at least part of the vehicle floor.

3. The railway vehicle carriage according to claim 2 , wherein the functional space for housing equipment extends beneath substantially a whole of the length of the carriage.

4. The railway vehicle carriage according to claim 1 further comprising a plurality of seats arranged on first platforms so as to accommodate passengers; said first platforms having a height substantially equal to that of the high floor levels, the intermediate platform comprising a zone which does not have seats so as to accommodate passengers with reduced mobility.

5. The railway vehicle carriage according to claim 1 wherein a first ramp of the ramps extends between the at least one high floor level and the intermediate platform and has a slope of substantially from 6% to 8%.

6. The railway vehicle carriage according to claim 1 wherein a first ramp of the ramps extends between the at least one high floor level and the low platform and has a slope of substantially from 5% to 7%.

7. The railway vehicle carriage according to claim 1 wherein a first ramp of the ramps extends between the intermediate platform and the low platform and has a slope of substantially from 6% to 8%.

8. The railway vehicle carriage according to claim 1 wherein a floor height of the low platform is variable substantially from 550 mm to 950 mm relative to rails on which the railway vehicle is to travel.

9. The railway vehicle carriage according to claim 1 wherein a floor height of the intermediate platform is substantially from 1000 mm to 1200 mm relative to rails on which the railway vehicle is to travel.

10. The railway vehicle carriage according to claim 1 wherein a height of the high floor levels is substantially from 1200 mm to 1300 mm.

11. The railway vehicle carriage according to claim 1 wherein a difference in height between the floor and a ground clearance of the railway vehicle is substantially from 400 mm to 700 mm.

12. The railway vehicle according to claim 1 further comprising a remote control for the vertical translation of the low platform such as can be used by a passenger of the railway vehicle.
