Annotation: The paper presents a theoretical substantiation of the positive effects noted by the results of tests of the modernized wheel pair, described in the author’s article «Influence of vibration on interaction of the wheel with the rail», published in the journal «Technics of railways» № 4 (60). In order to prevent derailment and improve train safety the rims of its wheels are separated from the wheel hubs and are capable of differential rotation on the wheel hubs as the wheel pair moves along the curved track. The wheel hub rolls along the inside of the rim like a rail. The results of bench tests and 10 years of full-scale testing of the modernized wheel pair in the subway on the railway and trams showed the effectiveness of this solution.The wheelpairmoves easilywithout sliding along the curved section of the path. There was very little wear on the rim and hub surfaces and the service life increased by a factor of 4 to 5. Therefore, no sliding but not sliding between the rims and wheel hubs. Anunusuallylarge creep~10%is realizedwhenthe wheel pair is rolling by inertia when only the curvilinear path influences its movement. This cannot be explained by existing theories of contact interaction.Therefore,whenanalyzingtherollingformation and the wheel creep on the rail, the influence of vibration on the site of their contact was taken into account. An asymmetric vibration along the contact area of the wheel makes it possible to turn the rotational movement of the wheel from the transport engine into a rolling track. Due to the inequality of the amplitude of the high-frequency oscillations,the wheel shifts in each oscillation along the track contact area in the opposite rolling direction. In the contact area of the bodies, due to the resistance of the friction forces of the surfaces,the wheel shear stops and the wheel makes, with the instant center of rotation in this place, an elementary rotation, which realizes its translationalmovement.Fromthenumerous consecutive wheel shiftsalongthe rail,apartofthe rotationalmovement of the wheel is converted into a translational movement and the wheel is rolled. The wheelrolling on the rail is in the form of very small, highly frequent alternating androtatingwheelmovements, the separation of which is imperceptible due to the high frequency and inertia of the wheel rolling. Numerous shifts form the wheel creep along the rail in the opposite rolling direction. From the creep the wheelrolling speed decreases. Sliding is mandatory when the wheel is rolling on the rail i.e. its shifts are necessary for turning the rotational movement of the wheel into a rolling movement. The use of rim sliding on the hubs of the modernized wheelpairwillincreasetheleveloftrainsafetyonthecurved tracks, reduce the wear of wheel and rail rims and reduce energy consumption.
Key words: vibration, wave interaction of bodies, wheel creep along the rail, differential rotation of rims of wheels of wheel pairs.
Annotation: The article presents a conceptually new approach to the issue of creation of a single digital space with the description of track development and infrastructure objects for subsequent increase of accuracy of existing electronic maps used on the railway network. The result of the work is tested on unmanned shunting locomotives and EMU “Lastochka” (Swallow). This approach is implemented in the digital model of track and railway infrastructure (hereinafter MPC) and consists in the applicationof an abstract mathematical approach, allowing to create a universal description of track development and railway infrastructure objects for a wide range of tasks from high-precision navigation to construction,reconstruction and repair. The key task when implementing projects related to digitalizationontherailwaynetwork,–ensuringsynchronize informationaboutJSCRussianRailwayspropertyobjects in the form of a single topology,thereby, firstly,reducing the costs of maintaining duplicate information and, secondly, excluding the human factor when making changes to information systems when updating data.

Overhead catenary systems installed on high-speed lines possess a number of unique characteristics that ensure safe and smooth train operation. This includes the increased tension of a contact wire, messenger cables and connecting wires; thermal endurance and wear resistance; increased mechanical strength of contact wires and cables; minimal mass of all structural elements but not at the expense of strength and durability; and reliable rust protection. To satisfy these stringent requirements, Ø 120-150mm2 low alloy copper or bronze contact wires are traditionally used. The contact wire shall have minimum sag, which is ensured by an overhead catenary system that uses closely spaced droppers to attach the messenger wire or catenary to the contact wire.

The opportunity to use data from a locomotive’s onboard microprocessor control system (MCU) to perform diagnostic tasks has been discussed ever since the first MCU-equipped locomotives became available. TMH-Service’s Maksim Gorky division initiated MCU data reading and manual transcription in the autumn of 2012, and in the summer of 2013 presented its first automatic workplace applications (AWA), which are offering semi-automatic diagnostic tasks using previously-developed diagnostic algorithms. On the back of this initial success, LocoTech’s Smart Locomotive project has set an ambitious task to automate not only MCU data development, but the whole diagnostic algorithm development process. By applying BigData and Machine Learning methods, the team working on the project is aiming to improve diagnostics objectivity by replacing the judgement of human engineers with statisticallyproven patterns, which are normally invisible to the human eye.
