Abstract Research purposes: With the train operation speed improved steadily，the impact of the disaster on the train operation is more obvious，the judgment time and reaction time for the driver while disaster comes to is also very short， so it is hard to avoid the impact of disasters by controlling the train manually. The natural disaster monitoring system must be set up to reduce the traffic accidents caused by natural disasters factors，and to ensure the safety of passengers’ lives and property. The foreign object invasion monitoring of the road bridge which crosses over the railway is one of the important components of tliis system. Based on the design example of typical foreign object invasion monitoring for bridge over multi - line adjacent area， this paper gave a specific design scheme， analyzed and researched to determine the structure，monitoring functions and design of the system in detail which can provide reference for design，construction， alteration and operation of similar engineering. Research conclusions： (1) In order to ensure the safety of running，when designing a foreign object invasion monitoring system of the road bridge which crosses over multi - line railway，the fail - safe principle should be obeyed besides the requirements from the code，and the equipment control should be prior made. (2) A thorough investigation is required before designing the system and the boundary of the centralized interlocking area should be decided reasonably according to the dispatch area，and the foreign object invasion monitoring networks which belong to different divisions should be designed separately on the consideration of easy operation and maintenance. ( 3 ) It is important to draw out a scheme that is optimized based on the specific interface used through technical communication with the suppliers. (4) The research result has a strong reference and guidance for similar project，and can be applied to the engineering design and operation of the railway natural disaster monitoring system.
