Prior to the practical use of a new wayside signal aspect for high-speed train in the Hokuhoku Line, the visibility and the compatibility of the signal, which is a double green aspect to come before the proceed signal with a single green, were tested. Twenty four test runs were totally performed using twelve drivers, along 30km line at 160km/h maximum speed. Drivers cleared each run without perplexity in the new signaling.
