Robotic High-Speed Rail Weld Grinder Model

Underwrite 32-stone autonomous rail grinding maintenance trains profiling steel rails and smoothing thermite welds to 0.05mm longitudinal tolerance at 15 km/h (extending track and wheel lifespan by 300% on 350 km/h bullet train lines). Model high-speed rail authority maintenance contracts ($1,850/pass-km), and fleet payback.
