ROCS (Rigid Overhead Catenary System) — a state‑of‑the‑art electrification solution that replaces traditional flexible overhead lines with a robust aluminium conductor rail clamped overhead. Built in modular 10–12 m sections and fitted with a copper contact wire, ROCS delivers uninterrupted 25 kV power directly to pantographs 

Ideal for space‑constrained environments such as tunnels longer than 750 m, low‑clearance bridges, station platforms, depots, and metro systems, ROCS eliminates the need for catenary wires, droppers, or tensioning devices—resulting in a more compact, reliable, and low‑maintenance design railmarketresearch.com+2scribd.com+2linkedin.com+2. With high current capacity (up to ~3,500–5,000 A), superior safety (no de-wirement risk), and simplified installation, it’s perfect for retrofitting into existing infrastructure without costly remodeling Global Railway Review
