Automated machine learning recognition to diagnose flood resilience of railway switches and crossings [PDF]

open access: yesScientific Reports, 2023
The increase in demand for railway transportation results in a significant need for higher train axle load and faster speed. Weak and sensitive trackforms such as railway switches and crossings (or called ‘turnout’) can suffer from such an increase in ...

Experimental Strain Measurement Approach Using Fiber Bragg Grating Sensors for Monitoring of Railway Switches and Crossings [PDF]

open access: yesSensors, 2021
Railway infrastructure plays a major role in providing the most cost-effective way to transport freight and passengers. The increase in train speed, traffic growth, heavier axles, and harsh environments make railway assets susceptible to degradation and ...

Condition Monitoring of Railway Crossing Geometry via Measured and Simulated Track Responses [PDF]

open access: yesSensors, 2022
This paper presents methods for continuous condition monitoring of railway switches and crossings (S&C, turnout) via sleeper-mounted accelerometers at the crossing transition. The methods are developed from concurrently measured sleeper accelerations and

Counterrail design with increased service life for advanced turnout switches

open access: yesВестник Научно-исследовательского института железнодорожного транспорта
Introduction. Counterrail is one of the constructive elements of modern turnout switches, which requires increased service life. The impact of railway rolling stock wheels on the counterrails causes high bending stresses in the elements of attachment to ...

Mathematical modelling of transients in the electric drive of the turnout of the mono-sleeper type with switched-inductor motor

open access: yesElectrical engineering & Electromechanics, 2021
Introduction. The study is devoted to the development of the functionality of a railway track switch by introducing a switched-inductor electric drive. This solution justifies simplifying the mechanical part of the switches by changing the gearbox to a ...

The Effect of Unsupported Sleepers/Bearers on Dynamic Phenomena of a Railway Turnout System under Impact Loads

open access: yesApplied Sciences, 2020
Track settlement is a common problem observed in ballasted railway tracks. The ballast bed and the material layers underneath it, deform under repeated trainloads and create uneven support conditions along the track. In some cases, the ballast settlement

Dynamic effect on turnouts of cars having wheelsets with thin flanges

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2020
Geometrical parameters of the “wheelset—rail track” system are mutually related. Currently, a very topical issue is the question of a possible adjustment of the regulatory framework in the “wheelset—rail track” system in order to take into account the ...

Guideway and turnout switch for the SupraTrans project

open access: yesJournal of Physics: Conference Series, 2006
This paper will deliver insight into technology and physics of the levitation system for the SupraTrans project, a prototype of a superconducting transportation system. The technology used herein bases on the flux pinning in melt-textured bulk YBa2Cu3O7-X (YBCO) that stabilizes the lateral and the vertical position of the vehicle above the magnetic ...
