To improve the durability of a floor coupling two vehicles, capable of following relative displacement of both vehicles when turning a curve, having traverse undulations for allowing passengers to move between both vehicles by walking on a top face of the floor, reinforcing the undulations by metal blades extending in a traverse direction, and providing an elastmer reinforcing structure portion between the blades of each pair of the metal blades.
Traverse dimension of each elastomer reinforcing portion is made 2L0, and each elastomer reinforcing portion is made from at least one elastomer piece 30. The elastomer reinforcing portion between at least one pair of the metal blades 15 adjacent to a longitudinal end 12, 14 of the floor is made from at least two elastomer pieces 30 separated from the longitudinal plane symmetry of the floor that is a plane parallel to the longitudinal direction.
