FIELD

The present disclosure relates to the technical field of railway trains, particularly to a railway train carriage and a railway train including the carriage.

BACKGROUND

A multiple-unit train is one type of railway trains, which includes at least two locomotives or powered carriages and multiple non-powered carriages. The multiple-unit train originates from double heading locomotive, but is different from the traditional double heading locomotive. Double heading locomotive, with an increasing number of locomotives rather than changing a type of the carriage being a trailer, is generally used for freight trains and is mainly to solve a problem of insufficient tractive force. However, the multiple-unit train is almost used for passenger trains only, mainly to solve a problem of insufficient acceleration and restricted maximum speed. Driving devices of the passenger train may be placed in multiple passenger carriages respectively, so that these carriages are powered, while a heading locomotive of the passenger train may become a trailer only having a console but without the driving force.
In a multiple-unit train, each carriage is equipped with a driving device, and a heading locomotive and the carriages are almost indistinguishable, or there is no heading locomotive. The train is entirely controlled by the railway system, and is mainly used in some urban railway transport trains such as maglev trains, APM (Automated People Mover) trains and ultra-high speed test trains and so on. The multiple-unit train generally includes two locomotives, multiple powered carriages and non-powered carriages. In some multiple-unit trains, the heading locomotive includes control equipment of the train and does not include the driving device.
Seats are arranged in rows in the carriage. In the conventional technology, the positions of the seats are fixed, and the spacing between the seats cannot be adjusted, and the number of seats cannot be increased or decreased according to the operation requirements.
EP2570322A1 published on March 20 2013 discloses a floor base structure. The floor base structure has a support element, at which the foot holders are fixed by an adjustment unit, where the support element is fixed at car body shell of the rail vehicle. The floor base panels are supported on the projection surfaces. The support element is covered with other floor base panels which are arranged between former floor base panels. The latter floor base panels are spaced from each other in the longitudinal direction of the rail vehicle and allow an access to the support element for fastening the foot holders to the support element.
