Abstract

A drop-frame urban rapid transit car includes passenger cells and travelling mechanism parts having a running gear, which are connected to one another at end surfaces by joint parts. The travelling mechanism parts disposed at ends of the car receive an engineer's cab. The object of the invention was to develop the drop-frame urban rapid transit car in a way which ensured the best possible utilization of the enveloping space and the best possible utilization of the available base area, a concept which makes it possible to construct a vehicle meeting the requirements of a modern urban rapid transit car, and at the same time with the most advantageous utilization of the necessary production devices, a minimum of different structural parts and a simple assembly. The object was achieved by providing that the passenger cell, the travelling mechanism part, the joint part and the engineer's cab be constructed as modules, and that each respective travelling mechanism module, joint module, passenger module and head module always have the same structure and be interchangeable independently of their location in the car.
