The invention relates to a computer-implemented method for detecting an anomaly of a rolling equipment rolling on rails of a railway resting on a rail support. This method comprises a decomposition (DECOMP) by discrete wavelet transform of a measurement signal (S) transmitted by a strain sensor detecting the deformation of the rail support into an approximation signal (A.sub.J) and a residual signal (R.sub.J) and a search (RECH-PA) for outliers (PA) in the residual signal (R.sub.J) in order to detect an anomaly of the rolling equipment.

Systems, devices, media, and methods are presented for controlling remote equipment in a network. A switch heater control system includes a weather modeling function. The system periodically obtains weather data according to a predetermined time interval. Based on the closest weather data set, the weather modeling function generates a hyperlocal forecast associated with each switch heater location. The system includes an active snowfall mode and a maintenance mode that controls heating based on an estimate of local snow depth, adjusted for wind conditions and passing trains. When the hyperlocal forecast indicates heating is required, the system calculates a melt duration, starts a timer, and transmits a start signal to the switch heater.

A Fit-For-Duty network system and method that integrates several drowsiness detection devices with software analytics engine to more accurately predict, monitor and/or detect an actual unfit-for-duty condition or positive event in real time. The system monitors behavior based on changing operational conditions (such as speed of vehicle and pre-defined conditions, such as time of day and geographic conditions) to dynamically estimate both seriousness and probability of a positive event. Moreover, based on estimated seriousness and probability of a positive event the system self-initiates different levels of alerts ranging from light and sound, to connection to a third party intervener (an operations center), to stopping the vehicle.
