Abstract (en)
[origin: WO2009109528A1] The present invention relates to a double-decker rail vehicle (1) having an upper deck (2) which extends in the direction (F) of travel of the rail vehicle (1), having a lower deck (3) which extends in the direction (F) of travel of the rail vehicle (1), wherein the lower deck (3) runs in a plane underneath the upper deck (2), and having a staircase (4) which connects the upper deck (2) to the lower deck (3), wherein the staircase (4) is a spiral staircase with a plurality of steps (5a, 5b,..., 5i) arranged in a helical shape. In order to form the connection between the upper deck (2) and lower deck (3) in as space-saving a manner as possible, the invention proposes that a plurality of steps (5a, 5b,..., 5h) are constructed and arranged according to the evolute method or circular cutting method.
