Definitions

  • the present invention concerns a railway vehicle with adjustable floor height, and more in particular, a railway vehicle having a floor whose height can be reversibly adjusted from a first level to a second level.
  • railway vehicles such as trams or train wagons
  • a floor which has, at least at boarding entrance areas, at least a given height with respect to the eight of on/off boarding platforms in order to allow barrier-free entrance or exit of passengers.
  • a part of a floor at a second different height might be provided inside the railway vehicle, in particular inside train wagons, and can be accessible by means of one additional step in accordance with the relevant Technical Specification for Interoperability or "TSI".
  • TTI Technical Specification for Interoperability
  • some railway vehicles may have a level of the floor relative to the platform level, in particular at the entrance area, which might not be suitable anymore for guaranteeing barrier-free entrance inside the vehicle itself.
  • train operators may request, for various reasons and more than once, for a change of the floor height.
  • EP 1808352 A1 discloses a vehicle which has a flooring construction designed as a modular flooring and includes a support that enables the lifting of the flooring from an exit height into a different height relative to a body shell of the vehicle itself. This different height is above the exit height and is arranged in a distance between a lower side of the flooring and an undercarriage of the shell, and the support laterally fastens the flooring at the shell.
  • EP 2778009 A1 discloses a rail vehicle having an access device comprising a platform which is moved vertically relative to a floor between high and low positions in which the platform is aligned and misaligned with the floor.
