Abstract：According to the technical requirements of a certain export railway passenger cars，a cableconnected ECP braking system for railway passenger cars based on network two-way communication and microcomputer management technology has been developed in accordance with the AAR Standards. It is mainly composed of electronic brake control device，air control valve，train network，and train tail device. Energy transmission，braking command transmission，state surveillance，and fault alarm are all realized through brake cables running through the whole train. The composition of the braking system，the principle of braking，and air supply control technology are explained in detail，and the functions of service braking，emergency braking， hand braking，anti-skid control，and derailment detection are introduced. Then，the service braking rate of the whole vehicle，hand braking rate and basic braking thermal load capacity are simulated and calculated.Finaly， the braking system has been submitted to single vehicle routine test，single vehicle type test and train formation test. The simulation and test results indicate that the braking performance of export railway passenger cars fully meets the technical requirements of the project.
