MRD has deep expertise in the rail transit industry, delivering full-scenario PIS network solutions – from classical high‑reliability redundant ring networks to ETB (Ethernet Train Backbone) networks compliant with the IEC 61375‑2‑5 international standard. Our TCC series industrial switches have been successfully deployed in benchmark projects such as Shanghai Metro Line 10. By supporting key technologies including TTDP (Train Topology Discovery Protocol) for dynamic consist, BYPASS power‑off bypass, and M12 high‑protection connectors, they address long‑standing pain points like manual reconfiguration after train re‑consisting, complex O&M, and excessive inter‑car cabling. This enables plug‑and‑play onboard networking and reliable operation throughout the entire lifecycle....
