JR West Adds Two Multifunctional Robots To Commercial Line Maintenance
JR West is moving its robot fleet from the ZIZAI trial stage into scheduled commercial-line work, and the machines are drawing attention online for how they look as much as for what they do.

JR West will deploy two types of multifunctional railway heavy machinery on commercial lines for equipment maintenance. A Heavy-Duty Single-Arm Robot, mounted on an aerial work vehicle, grasps objects up to 120 kg and begins use in October 2026. A Mass-Produced Humanoid Robot, made smaller and lighter with a longer boom, cuts trackside obstruction trees from November 2026. JR West targets roughly 30 percent less manpower.
The two machines split the work. The Heavy-Duty Single-Arm Robot sits on the deck of an aerial work vehicle and handles heavy objects up to 120 kg alongside workers, with use starting in October 2026. The Mass-Produced Humanoid Robot was made smaller and lighter with a longer boom, and takes on cutting trackside obstruction trees from November 2026.
JR West says the aim is mechanizing high-altitude work to prevent falls and electric shocks, cutting the manpower needed by about 30 percent, and letting people work regardless of gender or age. The company introduced the multifunctional heavy machinery ZIZAI in July 2024.
