The technique of express diagnostics of girder spans is presented, which makes it possible to determine the technical condition of girder spans of railway bridges. The technique is based on the analysis of the response of the structure to a small impulse effect – "a person's jump". Application of this technique will increase the service life and reduce costs for the current maintenance of railway bridges.
