The Gauge Change Equipment (GCE) is a ground system that changes the wheel gauge of Gauge Change Train (GCT) at a connecting point between two different track gauge sections. The development of this equipment was started in 1994, and the fifth version was installed in Shin-Shimonoseki maintenance depot on Sanyo Shinkansen line in March 2001. As a result of a total of 1,558 of gauge change tests with GCT, we confirmed that the GCE has sufficient strength and performance. We also verified the durability of support rollers using originally developed test rig.
