“…The conventional switch layout (shown in Figure 3) is for the C-switch in the UK rail network, for which the design speed is 25 mph (40.248 km/h) according to NR60 design of Network Rail [19]. Other railway S&C layouts, such as a stub switch layout, are also used in the rail network [20,21]. In the stub switch configuration (shown in Figure 4), the switch toe and heel positions are swapped.…”

Railway switch and crossing (S&C) systems have a very complex structure that requires not only a large number of components (such as rails, check rails, switches, crossings, turnout bearers, slide chair, etc.) but also different types of components and technologies (mechanical devices to operate switches, electrical and/or electronic devices for control, etc.). This complexity of railway S&C systems makes them vulnerable to failures and malfunctions that can ultimately cause delays and even fatal accidents. Thus, it is crucial to develop suitable condition monitoring techniques to deal with fault detection and diagnosis (FDD) in railway S&C systems. The main contribution of this paper is to present a comprehensive review of the existing FDD techniques for railway S&C systems. The aim is to overview the state of the art in rail S&C and in doing so to provide a platform for researchers, railway operators, and experts to research, develop and adopt the best methods for their applications; thereby helping ensure the rapid evolution of monitoring and fault detection in the railway industry at a time of the increased interest in condition based maintenance and the use of high-speed trains on the rail network.

“…The demonstrator is at 384mm gauge but all actuation components are sized for CEN-60 type rail, at the most common size of switch upon the UK infrastructure, termed a `C' switch. Note that extensive associated dynamic modelling work was undertaken in MATLAB/Simulink, in order to demonstrate the viability of the full scale design, presented in Bemment et al (2013a), Ebinger et al (2015) & Wright et al (2014. The demonstrator is a hardware-in-the-loop implementation of a full Repoint track switch.…”

Reproduced from [6] use of an actuating rod with machined teeth on the underside, and twin idler cams moving in phase with each other. Figure 2 shows a schematic layout of a single actuator-bearer unit.…”
