With the appearance and development of hump, the control technology of hump formation is becoming more and more perfect. Since Britain built the world's first hump yard in Liverpool in 1873, the United States began to use switch machines to operate the switches of hump yards in 189 1 to speed up the switch conversion. 1924, the United States began to use vehicle reducers to control the speed of trucks at Gibson station. 1948 adopts semi-automatic controller to control the train speed, and hump electric centralized control controls the train slide; 1952 A hump signal system was built in Gloria Park Jung Su, and the running speed of the train set was automatically controlled by an analog computer. 1956 an automatic control system for train formation disintegration was built in Gatoway, and the speed of peak-pushing locomotive and train group was controlled by digital computer. At the same time, countries have developed hump marshalling control technology and equipment, which has continuously improved the efficiency of hump shunting operation, further ensured the safety of operation and improved the quality of railway management.
China began to build mechanized humps in Sujiatun on 1943, and used vehicle reducers to control the speed. After the founding of People's Republic of China (PRC), some mechanized humps have been built in major marshalling stations all over the country. In the early 1980s, the marshalling yard of Fengtai West Railway Station adopted the governor to automatically control the retarder, and the Genshanmen adopted the retarder speed control system. 1985 nanxiang marshalling station began to use computer to control hump shunting.
