Interlocking (IXL) is a railway signaling sub-system. Its principal role is controlling the movement of points, the change of signal aspect and setting up tra c directions on a railway network. These controls are performed via commands on signaling system devices. The main issue of IXL concerns the safety of commands, or more precisely, properties preventing risks of train collision and derailm...

For high speed trains there is a potential risk of derailment when driving very fast and being hit by an extraordinary strong gust at the same time. The risk depends on both the wind speed and the angle between train and gust. Several techniques have been established to minimize this risk to acceptable values. To decide which of these techniques at a given site is most appropriate, precise know...

One of the key hazardous events in railways is signals passed at danger (SPAD). SPAD events are relatively common, most with minor consequence. However, SPAD events with catastrophic consequences happen sufficiently often to be a concern within the rail industry. A SPAD event is a precursor to a train collision or derailment; hence there is a strong focus on measuring and reducing their frequen...

Introduction: Differences in structure and function between the two brain hemispheres have generated great interest in neuroscience, revealing the developmental origins of lateralized cognitive functions and hemispheric specialization of neuronal circuitry [4]. Anatomical asymmetries develop in utero and increase during childhood, so any derailment in the course of neurodevelopment may lead to ...

This contribution is an overview on the role of noradrenaline as neurotransmitter and stress hormone in emotional memory processing. The role of stress hormones in memory formation of healthy subjects can bear significance for the derailment of memory processes, for example, in post traumatic stress disorder (PTSD). Increased noradrenaline levels lead to better memory performance, whereas block...

To reduce the occurrence of accidents during train-to-train collision test, it is necessary to carry out research on derailment protection. According characteristics a method using U-steel as guard rail proposed. The protection range obtained through geometric relationship. ability and damage risks in different impact conditions, velocities, installation positions are studied. Additionally, sec...

adhesion level for the proper running of rail wheelset on track is crucial problem in detecting slippage to avoid accidents. the slippage of rail wheels has been observed applying forward and lateral motions to slip velocity and torsion motion. the longitudinal and lateral forces behavior is watched with respect to traction force to note correlation based on angle of attack. the deriving torque...
