Design of a Height-Adjustable Boarding System for a New Double-Deck Railway Vehicle

This paper deals with a solution for faster and safer boarding and leaving of passengers at railway station platforms from 150 mm to 550 mm higher than the head of the rail. This conception is based on the requirements of railway infrastructure administrators, transporters and also manufacturers of passenger rolling stock. This device is designed for the new double-deck railway vehicle for suburban and regional transport, which fulfils legislative and normative requirements that are specified for the selected area of vehicle construction and operational features. Selected parts of the construction were verified through a series of simulation analyses. This article also includes a study that deals with optimization of the boarding area considering designed changes in the construction of the floor and a draft for modification of the vertical clearance of the boarding entrance area in a rough construction of the vehicle.
