Integrated estimation procedure of technological stability of freight station

The questions of estimation procedure preparation of technological stability of freight station functioning are examined. Doing so it takes into account that technological stability of freight station functioning depends on operational reliability of its technological subsystems. In this article there are the formulas allowing to determine an additional waiting time of beginning of maintenance in the freight station unit if there are refusals, and also the total excess of the standard time of car staying in the concrete unit.

To the question of standard check automatization of ferroconcrete superstructures of overhead roads

The mathematical model with which help it is convenient to automatize the standard checks of cross sections of ferroconcrete superstructures of overhead roads of any configuration is offered. The spatial case with three-component loading is examined in detail. The generic description of assigned task solution algorithm and the example of implementation are resulted. It is shown how in the given model it is possible to present the standard checks of ferroconcrete superstructures.

Application of nonwoven materials for complex safety protection of passenger cars of a railway transport

The nonwoven linen material NO- L-1 and on its basis - the composite duplicated material NO- L-1Ђ are developed and put on serial production. The latter consists of a nonwoven substrate on one side of which an aluminium foil is fixed with the help of heat-resistant glue. This material is recommended to use in the internal equipment of passenger cars of new construction and after overall reconditioning.
