Automated machine learning recognition to diagnose flood resilience of railway switches and crossings. [PDF]
Sci Rep, 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]
Sensors (Basel), 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]
Sensors (Basel), 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

New Insights from Multibody Dynamic Analyses of a Turnout System under Impact Loads
Applied Sciences (Switzerland), 2019 A railway turnout is an essential infrastructure for managing railway traffic flexibility. In contrast, it imposes restrictions on train operations such as lower operational speeds through the turnout due to the complex movements of trains over the ...

Counterrail design with increased service life for advanced turnout switches
Вестник Научно-исследовательского института железнодорожного транспортаIntroduction. 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 the counterrail pads with stop blocks.

Ensuring transportation under turnout switches loads exceeding design and regulatory criteria
Вестник Научно-исследовательского института железнодорожного транспортаIntroduction. The need to rapidly increase the volume of railway transport is ensured by the use of heavy-load trains of increased weight and higher carriage axle loads. The capacity of the railway infrastructure does not always allow for unlimited use of such traffic organisation.

Engineering solutions to improve conditions and smoothness of train traffic on turnout switches
Вестник Научно-исследовательского института железнодорожного транспортаIntroduction. The currently used turnout switches geometries provided for the development and serial production of the main types of turnout equipment that ensure the transport process on the Russian railways. Further development of the infrastructure and the turnout facilities as its most important component calls for new, more advanced turnout ...
