Abstract Research purposes: 20 000-ton freight train has run on Datong-Qinhuangdao Railway Line, mainly consisting of C80 open wagons which are made of aluminum alloy and stainless steel chassis. 200 wagons are made up train in Hudong station and train runs to Qinhuangdao direction. The arrival and departure tracks available for operation of 20 000-ton train are laid out in Hudong station. It is necessary to carry out the technical operation to train in Hudong station in order to guarantee the train arriving at destination safely, but the conventional technical examination facilities cannot meet the require of the train technical examination. Therefore, it is necessary to make research on the new safe protection mode of train examination and the wayside facilities for testing train braking system in order to meet the requirements of the daily technical examination for trains made of 50, 100 and 200 wagons for the purpose of guaranteeing trains running safely and providing the safety for the train inspector.
Research methods: The research is made on layout mode of intermediate switch (web switch) and analysis is also made for applicable mode and the operation flow sequence of arrival and departure tracks in station and yard. The simulations are made for trains' parking locations in four sub-areas of arrival and departure tracks under different modes of makeup train according to traction modes of Modified SS4 and DJ Model electric locomotives, service operation procedure of locomotive passing in and out the depot, and length of new type locomotive. The research is made on essential conditions available for train's daily examination and the feasible and new layout mode of facilities available for train examination is offered.
Research results: The reasonable safe protection facilities and the wayside facilities for testing train braking system available for various conditions of running 20 000-ton trains shall be chosen.
Research conclusions: The electric derailers should be installed at both ends of line for train examination, manual derailers should be installed at intermediate web switch, and 4 wayside air-testing executors should be set for each track and the facilities for testing train braking system should be equipped with link status.
