In the compressed state of the compression springs, the coils in each spring are in a common plane with one another and are free of contact with one another.

Abstract: A method for performing operationally prescribed brake trials before the departure of a railway train, utilizes an indicating and diagnostic system disposed on board the train and operated by the train driver. Sensors in the braking system of each car bogie supply information signals representing pressures, travels and forces to a bogie processor which is connected with a car processor. The car processors are connected by a continuous data bus line with a central processor. The central processor processes the operational information from the brake system according to a processing program into status reports such as general status indications, fault diagnoses and maintenance instructions. The indications and instructions are visually displayed on a monitor and a printer, and acoustically reproduced by a speech synthesizer through a loudspeaker. The car processors are programmable by means of mobile computers and interrogatable by means of pocket terminals.
