During more than half of century period of use the typical construction of upper building metro railway with wood ties and strengthening "Metro" a number of disadvantages has been discovered. The main of them were heightened level of noise and vibration, traction current leakage, low repairability, higher costs at current keeping etc. Because of exceeding the sanitary regulations noise and vibration level in buildings, border upon metro railway lines shallow foundation, enhancement of railway construction in today mainly direct to solve this problem. In article has been viewed main constructions of upper building and strengthening of metro railway, analysed particular qualities of their exploitation and suggested technical decisions on development a new construction with heightened protection against vibration properties.
