Abstract

In the masters work „The supervision and durability of railway points and their parts” I analyst the constructions of the existent railway points and their types, viewer the technical state of the railway points that „Vilniaus geležinkelių infrastruktūra”, a branch of „Lietuvos geležinkeliai” changed last year. The interaction of the railway points and the wheels of the railing – stock when a train rolls through the parts of the railway point is analysed. The ways and possibilities to enlarge the durability of the railway points and their parts is viewed. The rules and norms of the railway point service are examined. In order to explore the influence of the deflection of the railway point geometrical parameters to the wane of their parts, the works of levelling and measuring the geometrical parameters of 17 railway points and their parts fitted in 2003 has been done. The received measurement result data has been analysed. The economic affect of the railway point durability enlargement tentatively counted. At the end of the work, on the ground of the measurement results and their analysis, the conclusions are formulated and there are also proposals how to prolong the durability of railway points and their parts
