Abstract. In order to ensure an inclusive approach to railroad station infrastructure maintenance, pilot project for AMEL – type combined rail heating and lubrication system is implemented since 2015 as a part of «Rail transport resource conservation technologies» investment program. Pilot project was aimed at designing the automated system that is up to modern technical standards and is compatible with current Automated Control Systems at russian railways. Goals of the development were optimization of financial, energy and human resources usage as well as increased efficiency in operating of railroad station infrastructure. AMEL system is designed for clearing railroad switches from ice and snow, lubrication of railroad switches and providing an electric plug for portable devices with a possibility of remote performance monitoring and system control.

Abstract. The article describes the test results of the Project 2946 turnouts on a reinforced concrete base with screw-dowel fastening for tracks of marshalling yards. The data on the working of turnouts equipped with screws from various manufacturers are given. Proposals for improving the design of screws in order to increase their operational stability are presented.

Abstract. The article presents the results of controlled operation of cars with increased axial loads up to 27 t/axis at the test site Kachkanar—Smichka Sverdlovsk railway.



Excavation device in the arctic tundra


Keywords: roadbed, excavation, Arctic tundra, snow transfer, snow protection structures, permafrost.

Seleznev Alexey — engineer, Director General Institute «Giprotransproekt». St. Petersburg, Russia.


Abstract. In the existing normative documents it is recommended to design the roadbed of Railways and highways in the permafrost zone in the General case, if possible, in embankments. However, the refusal of recesses in the design of Railways and roads leads to a sharp rise in the cost of construction. In the Arctic tundra, there are two problems that complicate the use of excavation: heavy snow transfer and the presence of high-ice soils, and often buried ice. Heavy snow transfer requires a strong opening of recesses (gentle slopes), but this can not be done, because the violation of the surface layers of the soil leads to thawing of the bases and sometimes catastrophic shifts and destruction of nearby massifs. The way out of this impasse lies in the use of tunnel-type recesses, in which the surface disturbance is minimal. The article analyzes two examples of the use of tunnel type recesses, in which a significant environmental effect is achieved.

Abstract. The article provides results of experimental studies to evaluate the influence of wet splashes on force and kinematic parameters of the interaction of passenger and freight train wheels and track. It is established that values of vertical forces and rail deflections are higher when moving along a wet splash than in the reference section: values of vertical forces are 1,35—1,8 times higher, values of deflections are 6—11 times higher.
