Development and Progress of Braking Technology in the Heavily Loaded Train

This paper briefly introduced the efforts that our country had made for development of heavily loaded train for fifty years.while using the steam locomotive to traction,we have carried on the test about braking,alleviating and inflated time on the 120 freight trains.In 1958 we started to develop and test the freight vehicle single line electro-pneumatic brake equipment.Along with the diesel locomotive and the electric locomotive development,the heavy load train technology was impelled from developing 103 air operating valve in 1961 to promote 120 control valve currently the condition for the heavily loaded train has been created.In 1985 the air synchronization brake equipment and the locomotive wireless remote control synchronization operation have been experimented.The data obtained from these experients have provided the help for the development of the heavily loaded train.
