The Diesel engines and electric motors fitted in the newly developed duo-buses drive the rear vehicle axis alternately (rear wheel drive). A generously illustrated detailed survey with tables and diagrams gives information on structural, functional and test characteristics. Starting from considerations of economy, the vehicle design is shown and design details of the vehicle are described (construction of vehicle, wheels and axles, arrangement of axles, braking system, wheels, tyres, springs, steering) and the electrical components (driving motor, DC controller, ventilation/cooling, braking resistance, current pantograph, accessories). Experience is given on its use, testing and operation. The relatively high manufacturing and running costs of the duo-bus are regarded as a disadvantage. However, the advantages consist of the lack of waste gases (in electrical operation at site), the better use of energy with regenerative braking feedback to the mains supply and the greater independence from petroleum, as well as the only partial electrification of the line network, which is necessary.
