Abstract: A track identification system for a plurality of locomotives moving on defined plurality of tracks of a railway network wherein the system consists of on board computers with track data and identifiable switching locations data and the parameters of movement of the locomotives along the said tracks, the computers receiving reference location signals of the locomotive from a global positioning system and different geographical locations of the locomotives and digitally map the determined geographical locations on the stored route and track data, the computers continuously monitoring the movement of the locomotives with reference to specific parameters to compute the angular velocity change profile to determine switching actions at the said switching locations and generate signals relative to the angular change profile relating to switching actions at the switching locations to determine the tracks on which the movement of each of the locomotives is occurring and the velocity of such movement.

Abstract: A track identification system for a plurality of locomotives moving on defined plurality of tracks, said tracks having uniquely identifiable switching locations where said locomotives can switch movement from one track to movement on to one or more other tracks, said tracks passing through a railway network consisting of locomotives, stationary structures such as stations, crossings, yards, said system consisting of on board computers fitted to each of the locomotives, said on board computers having storage means to eraseably store digitally encoded information of at least a portion of the route and track data relating to the said plurality of tracks, each of said uniquely identifiable switching locations, and the parameters of movement of the locomotives along the said tracks, said computers having processors programmed to receive reference location signals of the locomotive from a global positioning system and thereby determine the precise geographical locations of the locomotives, said computers further pr

Abstract: The Anti-Collision Device (ACD) for the trains and the like transportation system, which prevents collision between the trains and between the train and other vehicles. The invention includes a microprocessor based central processor in the nature of a command and control unit, a receiver with a satellite signal antenna for receiving signals from a global positioning system, a crew interface of desired capacity/range with directional antenna and an Input/Output system, a brake actuator linked with the brakes for locomotive speed control, a message display unit having audio and/or visual display and a power supply system. The power supply system includes a battery and power converter, and all units and system are functionally interconnected.

Abstract: An anti-collision device for trains and the like transportation system comprising of a microprocessor based command and control unit (CCU), a Global positioning system (GPS) with satellite signal receiver antenna, a crew interface of desired capacity/range with directional antenna, an 1/0 sub system, a braking signal unit linked with braking mechanism for locomotive speed control, a message display unit having audio and/or visual display means and a power supply system, preferably consisting of a battery and power converter, all units and systems functionally interconnected.

Abstract: A suspended transportation system comprising an extended continuous hollow box way having a slot throughout its operative under wall, said box way being elevated by columns from the ground level and generally following the lay of the ground; a pair of rails fixed on either side of the slot on the operative inner surface of the under wall within the extended box way and extending continuously throughout the box way; a plurality of bogie assemblies moving on the said rails within the box way secured to a floating beam located in the box way operative overhead of the bogie assemblies suspension means extending from the floating beams operatively downwards and through the slot in the box way; coaches suspended from suspension means; and motor means to displace the bogie assemblies on the rails. A derailment control safety device is also disclosed.

Abstract: A method and apparatus for clearing an immobilized and or derailed suspended coach is described. The suspended coach forms part of a suspended coach transportation system in which suspended coaches suspended from a suspender beam fitted to a conventional rail bogie with wheel sets moves on rail fitted in a concrete box guide way. The method and apparatus involves extending the suspender beam to make it longer than the coach body and providing the ends of the suspender beams with n extensor and lifting mechanism for permitting an assisting mobile coach to use its suspender beam to lift an immobilized coach at its suspender beam and carry or push the immobilized coach for clearance. A method of clearing an immobile or derailed suspended coach in a suspended coach transportation system is also disclosed.
