The article discusses the issues of implementation and organization of high-speed transport. The objective of the article is to consider possible options for implementing highspeed (HS) motion systems using the principle of magnetic levitation, which will ensure high speeds for delivery of goods and carrying people over long distances. To achieve this objective, it is necessary to develop an engine and technical solutions for design of HS rolling stock, make decisions on energy supply infrastructure and the HS track, address safety issues and new control systems considering the state of the infrastructure and its design elements. The article discusses several options for implementation of high-speed transport systems, differing in the power supply system, current collection and track based on the magnetic levitation approach. An original approach is proposed in implementation of magnetic levitation transport using the technology of electromagnetic guns designed to implement traction forces of a magnetic levitation vehicle. The advantage of this approach is that it opens the possibility of maneuvering for the vehicle while driving. This allows to abandon switch turnouts, now significantly limiting the use of magnetic levitation transport. A mathematical model describing interaction of an electromagnetic gun and supermagnets located on the track is considered. In constructing the model, methods of the theory of electromagnetic field and interaction of magnetic bodies were used, and when constructing a model of interaction of rolling stock with a magnetic track, methods of mathematical algebra and the Cauchy theorem were used. The article discusses various principles of organization of movement using the magnetic levitation for urban, suburban, and intercity transport.

Modern Rolling

Modern rolling stock must have high reliability, as it provides high-speed movement of goods andpassengers. This applies to all its constituent parts, components and assemblies, particularly those thatprovide traffic and security are the foundation of the locomotive as a whole. Since from here it is necessaryto assess the reliability of mathematical responsible units of electric rolling stock and, in particular, currentcollectors.The stability of the current collection at railway roads depends on many factors, including thecharacteristics of the pantograph and contact network. Interaction pantograph suspension and contact is acomplex process, especially at high speeds. To ensure continuous quality current collection and Currentcontact network must have high reliability.In case of refusal trolley stops rolling stock supply electricity. This can lead to temporary, economicor material costs. To avoid this, specify resource pantograph and yohoskladovyh.
