Coaches feature stainless steel alloy body frames, moisture-resistant thermal insulation in weather-exposed nodes, and thermal sensors in axle-bearings. Their cradle-less bogies with 2-stage spring suspension ensure a smoother ride, and disc brakes with antiskid system contribute to safety. https://www.railwaypro.com/wp/enr-passenger-cars-to-enter-ce...
Unlike cradleless designs, cradle bogies can achieve larger angles of rotation compared to the vehicle body, which is particularly important in the case of curves with small radii. https://wikicali.com/wiki/bogie/
