Abstract: A system and method for recommending intelligent railway network access plans and modified access plans based on current status of execution of tasks and train timetables. Herein, the system and method need to consider multiple variables including train timetable changes, activity efficiencies etc. to derive an overall optimum access management solution for the railway network. They can interface with existing operational timetables and cost management systems by using existing data sets for operations and cost data. The cost data is manipulated to identify fixed and variable costs and variability of variable costs with access duration and activity bundling. A trade-off between cost and value is considered which results in a longer continuous time window being available for maintenance, less visits to same location to complete a maintenance task, less time spent in setup/unwind activities and higher labour utilization.

The main computer is programmed so as, in the “standby” mode, to verify that the movement of the train measured by the odometry device from the switching from the “active” mode to the “standby” mode is zero and, in the affirmative, to send the ground ATC an instantaneous position of the train using the radio communication device.

A braking force generated by an axle with a small axle load is reduced according to a load-decreasing amount of the axle load, while a braking force generated by an axle with a great axle load is increased according to a load-increasing amount of the axle load, so that the braking forces generated by the axles match the axle loads.

Abstract: Each train detects its location, velocity, and the time it will spend to pass the next bifurcation, joint, and intersection, respectively, and sends the information periodically to the trains that are or will be behind the train. The controller of each bifurcation, joint, and intersection, respectively, having mechanical movement sends the connection status of the track to the trains about to pass it. Then, receiving a message, a train can determine if it may hit its front train if its front train stops abruptly and if it may pass the bifurcation, the joint, and the intersection, respectively, before the track there has been connected for it. If yes, the train decelerates to stop to avoid possible disasters. So that the distance between every two consecutive trains can be minimized and different kinds of trains may share the same railroad. Hence, some railroads may be saved.
