This paper has described the experimental research on waterborne epoxy primer，waterborne polyurethane intercoat，waterborne polyurethane topcoat，waterborne polyurethane basecoat and waterborne polyurethane clearcoat for rail transit vehicles，and the samples were selected from the representative waterborne coatings suppliers for rail transitvehicles at home and abroad，which were tested focusing on neutral salt spray resistance，UV resistance，harmful material content and fire retardant performance，and a comparative analysisof these properties and the mechanism of the influencing factors were also conducted.All thesamples selected in the study basically represented the highest level of waterborne coatings forrail transit vehicles at home and abroad，and provided an important research data basis for thetransition of rail transit vehicle coatings to green and environmental friendly systems.
