Abstract: Disclosed is a computer-implemented method for determining dynamic braking data for use in a braking model of at least one train, the method including: (a) determining at least one initial safety factor; (b) determining at least one dynamic braking adjustment factor based at least partially on (i) the expected dynamic braking force, and (ii) specified retarding forces of the train; and (c) determining at least one new safety factor based at least partially on the at least one initial safety factor and the at least one dynamic braking adjustment factor. Also disclosed are braking systems including dynamic braking for a train having at least one locomotive.

Abstract: A packet switched multi-mode mobile communication network and fixed and mobile devices for use therewith are disclosed. Each of the mobile vehicle equipment and a base station packet switch are coupled to respective data terminal equipment which generates packet data messages. The packet data messages have message characteristics associated therewith. Each of the mobile vehicle equipment and the base station packet switch have an intelligent switching node incorporated therein for selecting which of a plurality of radio frequency transmission paths to use in transmitting the packet data message to the other of the mobile vehicle equipment and the base station packet switch. Each of the plurality of radio frequency transmission paths has transmission path characteristics associated therewith.

Abstract: An electronic air brake control system which utilizes an inter-car distance measuring sensor for determining the distance between adjacent railcars and thereby determining the coupling slack and also determining the performance and response of railcar brake applications. The system providing the capability of controlling the slack to increase or decrease slack at a controlled rate and further for monitoring and regulating the amount of pneumatic brake signal required to produce a predetermined level of wheel resistance, together with a system and method for applying railcar brakes when predetermined characteristics relating to distance between cars and rate of change of distance between cars meets predetermined characteristics.

Abstract: A system and method for monitoring and reporting out-of-route mileage for long haul trucks which includes transmitting route data from a dispatcher to a distant truck where comparisons aboard the truck are made of its current position with predetermined acceptable positions and exception reports are generated and transmitted back to the dispatcher from the truck if the current position is not included in the set of predetermined acceptable positions.
