  2. Development objectives • Providing speeds on lines being reconstructed for speed and high-speed traffic 2. Speed increase at station entries

  3. 1. Providing speed on the lines being reconstructed for speed and high-speed traffic

  4. Switch of R 65 type, 1/11,( under the project 2956) and exchange track on its basis (project 2968) Design speed: on straight main line of the switch - 250 km/h; on side line – 50 km/h 7 | Switches| 10.2012| VNIIZHT

  5. Speed increase of train traffic through switches(under the project 2726) Design speed trough the switch – 200 km/h Speed through the upgraded switch – 220 km/h 2| Switches| 03.2012| VNIIZhT

  6. Vibration of switch at speed of 220 km/h Before modernization After modernization

  7. Speed increase of train trafficthrough switches(under the project2750) Design speed through switch – 140 km/h Speed after upgrade of the switch – 160 km/h 3| Switches| 03.2012| VNIIZhT

  8. 2. Increase in traffic speed at station entries

  9. Dynamic-kinematicalcharacteristicsof typical projects ofswitches in Russian railways 4| Switches| 03.2012| VNIIZhT

  10. The rate of acceleration changewhen entering the turnout curveandin the body of passenger car while passingturnout 5| Switches| 03.2012| VNIIZhT

  11. Dynamic-kinematical characteristics of suggestedturnouts 6| Switches| 03.2012| VNIIZhT

  12. Switch of Р65 mark 1/22Speed of movement on a straight main line - 250 km/hSpeed of movement on side line - 120 km/h

  13. Offers to a cooperation Team work in development of switches of flat marks for high speed traffic 1 Industrial engineering in Russia of switch parts base on European producers 2 Using VNIIZHT methods in research work, their aim is to improve design speed of turnouts 3

  14. CONCLUSIONS: Development of newand modernizationturnouts in current operationisthe effective toolto increase speed of trains Effective use of switchesfor transportationcan be increased due toincreasing traffic speedsin the yard neck It is possible to increasetraffic speedon switchesand its combinationsat the branch, without yard neck reconstruction, with minimum coststhrough the use ofnew geometryof switch curves It is possible tominimize the costs to increase train speedson straight track of switchthroughits modernizationdirectly on tracks. 7| Switches| 03.2012| VNIIZhT
