... personnel must select the defect installation and the manner of signalling manifestation thereof. Following the answers given by the maintenance personnel (resulted from the observations and / or measure- ments) to key questions, the application will display the following questions that must be answered (Fig. 5) or the cause of failure (Fig. 6). The software allows the return to the previous questions and resuming of questions, having a friendly interface, without the requirement of specific knowl- edge of computer ...

The entry signal of a Romanian railway station is an installation that allows or forbids the entry of a train in the station. Together with other, interconnected installation, the entry signal insures the railroad traffic safety. Any defect to the signal cause train delays, signal malfunctions may cause railroad traffic events. The diagnosis method proposed in this work comes to the aid of railroad maintenance staff by reducing the diagnosis times. This method is based on specially designed diagnosis diagrams, which are in turn based on electrical schemas of Centralising Electrodynamic block-and-interlocking installations. The diagrams are used by a software package that allows maintenance staff to perform failure diagnosis on modern hand-hold devices. The software package substantially reduces the failure diagnosis time for a malfunctioning entry signal.
This article presents a method for the computerized diagnosis of entry lighting signals in a CFR railway station. The railway station is controlled by a Electrodynamic Centralized type 4 block-and-interlocking installation. The work presented here deals with interrupted glowing wire signals of the red light and with the inability to command the call signal. The proposed method substantially shortens the diagnosis time and, therefore, shortens the delays in railroad traffic. The method is based on diagnosis charts which, in turn, are used to devise a specialized software, which allows fast and accurate detection of signal defects. The diagnosis software does not interfere with the traffic security, can be used in maintenance staff training sessions. The software runs on personal computers as well as on mobile devices.
