Abstract: This invention relates to a method and system for the operation of trains on a rail network, and has particular application in the context of long-haul rail networks. The invention provides a method and system which monitors the progress of a train on a long-haul network, calculates efficient control profiles for the train, and displays driving advice to the train crew. The system calculates and provides driving advice that assists to keep the train on time and reduce the energy used by the train by: (i) monitoring the progress of a journey to determine the current location and speed of the train; (ii) estimating some parameters of a train performance model; (iii) calculating or selecting an energy-efficient driving strategy that will get the train to the next key location as close as possible to the desired time; and (iv) generating and providing driving advice for the driver.

Abstract: A multipath interference reduction system and method for smoothly reducing noise associated with FM stereo signal reception with an adjustable blend. The system includes a peak detector for detecting noise present in the received signal. When the detected noise exceeds a first threshold limit, stereo separation reduction is provided. The amount of stereo separation reduction may be adjusted so as to provide a greater reduction at higher noise frequencies than at lower noise frequencies to enhance the audio sound. When the determined noise exceeds a second higher threshold limit, stereo separation is further reduced to provide primarily monoaural reception.
