The invention provides a rail transit steel rail transition resistance detection system and a rail transit steel rail transition resistance detection method. The system comprises a steel rail insulation joint, a power supply, an acquisition module and a server; the steel rail insulation joint is arranged at the steel rail reflux position, the steel rail between the two insulation joints is a section to be measured, both ends of the section to be measured are respectively connected to the cathodes of a first traction substation and second traction substation through a first reflux line with a first electric isolating switch and a second reflux line with a second electric isolating switch; the power supply is respectively connected with the section to be detected and a drainage network, andthe acquisition module is respectively connected with the section to be detected and the drainage network; during normal operation, all the isolating switches are in a normally closed state to ensurenormal traction of a locom
