Control of safekeeping of railway cars at points of technical transfer

The article presents the analysis of damage of freight cars at transfer points for freight cars. The analysis of malfunctions of railcars stepping off the tracks of non-public use enabled us to determine that most of the railway cars have damages common for loading and unloading operations. It is possible to ensure the safety of railcars by applying, in particular, digital technologies, including when receiving freight cars from non-public railway tracks. It is noted that for the points of technical transfer of railcars (PTTW) as a subdivision of technical service points (TSP), the main form of internal primary accounting is the book VU-15 («Book of full-scale inspection of railway cars at technical transfer points»), the electronic format of which is only being introduced into the production process. The special significance of the transition to the electronic version of the VU-15 is manifested in enterprises with several PTTW, where railway cars transferred to the access railway through one point can be returned to the railway through other points. Often, the electronic form of the VU-15 greatly limits the capabilities of railcar inspectors when working on the tracks (operational search for data on railcar malfunctions, the possibility of photo and video recording of damage, the use of regulatory and reference information). The solution to these issues can be the use of mobile workstations (MWS) with additional functions for monitoring the safety of railway cars, which allow monitoring the technical condition of the freight cars before they are delivered to the non-public track and returning them to the infrastructure. Within the framework of the conceptual project, the AWS MWS PTTW structure for monitoring the technical condition of freight cars and the algorithm for processing information in the MWS PTTW for monitoring the safety of railway cars with the practical implementation of software in C# were developed.
