ABSTRACT

Cold climate regions need railroad ties with improved operational characteristics during the construction and repair of railroad tracks. The aim of the study is to create a technology and equipment allowing the manufacture of such sleepers. Low-value soft hardwoods, oily antiseptic, and drying press chamber are needed for the production of sleepers with improved performance characteristics. Technological modes for producing sleepers with high performance characteristics of softwood have been tested using the installation which enables to combine technological operations - drying, treatment, and wood pressing. The resulting sleepers can be used in the Extreme North conditions. The half ties have been laid at Chistye Prudy metro station in Moscow, and the ties have been laid at Scherbenka station on the experimental ring of Russian Railways (JSCo «RZD»). The tests have been carried out for four years in underground railway system and for two years on the ring of Russian Railways. The test results have found that wear of modified sleepers and half ties is about 3 times less than wear of pine sleepers and the average service life of sleepers made of modified wood will be about 50 years. An experimental batch is currently being manufactured.
