 The radius of the curve is only , meaning that the platform curves approximately 77.5 degrees between its front and back ends.The platform accommodates the first five cars of a train, but the rear five cars of a 10-car 1 train cannot load or unload.In addition, spray nozzles are required to lubricate the track to reduce the friction caused by the tight curve, which slows train operation and generates a loud metallic scraping noise.
