Expansion of the field of use of ashes from recycling of waste wooden sleepers

The structure formation at replacement of cement with ashes from wooden sleepers burning in a storage time is investigated. Recommendations for formulation of composite solutions with use of ashes from wooden sleepers burning are developed. It is ascertained that it is possible to replace 20% of cement with ashes from wooden sleepers burning lossless technological parameters of a solution.

Distribution of heavy metals in a right of way of Pokrovskoe-Streshnevo-Leningradskaya section of Riga direction of Moscow railway

Distribution of heavy metals along the railway section near Pokrovskoe-Streshnevo park zone is considered. The soil of a right of way rates as a category "dangerous" in a place of electric trains braking and intersection with Moscow loop railway. The braking distance is computed and its conformity with distribution character of metals of 1-2 classes of danger is proved. The primary contribution to soil pollution by a railway in comparison with a road is revealed.

To realization of the Comprehensive program of phased transition to the organization of freight trains operation according to schedule on Russian railways

The basic trends of realization of the Comprehensive program of phased transition to the organization of freight trains operation according to schedule are considered. The improvement ways of the organization of operational work of railway directions for the purpose of realization of technologies of transportation work on principles of "the fixed schedule", including low-activity lines, advantages of such technology with the account of differentiated control of car traffic volumes are shown.

Determination of dependence of an average number of trains in turn on a junction at their strictly uniform approach at integration of a train traffic volume arriving from other directions

Process modelling of train operation at various combinations of average intervals of arrival of trains from different directions is carried out. Results of modelling are submitted. It is established that at high filling of capacity of a subsequent section the requirements for track development of a junction sharply grow and waits periods of trains on it are essentially increased. Results of work are useful to the rational organization of transportation process in conditions of transition to the organization of freight traffic according to schedule.
