RAPID RAIL MAPPING WITH GPS AND OTHER SENSORS

Simulators are designed to duplicate real train journeys for driver training. At the heart of the simulation is accurate survey information describing the vertical and horizontal profiles of the rail track. At one level, poor quality in the survey information is immediately evident when the reaction of the train under simulation is not consistent with the track profile seen in the video images provided by the simulator. However, simulators are also used to develop train driving regimes to optimize fuel consumption and poor survey information undermines this more critical aspect. The classic approach to gathering accurate survey information would necessitate traversing with theodolite and EDM and with thousands of kilometres to be surveyed, the cost would be prohibitive. The Global Positioning System appears to be an appropriate technology for rapid track mapping to meet the needs of train simulators.
