Retractable door step arrangement for bridging gap between passenger compartment and platform has arrangement for connecting door step and extension that extends tread plate to adjacent platform

摘要

The device has a single door step with a tread plate part and a connecting part for connecting to a retraction mechanism (70) for moving the door step in and out relative to the adjacent platform, a door step extension and a connection arrangement (90) for connecting the door step and extension, which extends the tread plate to the platform. Independent claims are also included for the following: (a) a method of manufacturing a train with optimal bridging gaps between platforms along its route and the passenger compartment (b) and a method of adapting a train for optimal bridging of gaps between platforms along its route and the passenger compartment.
