Tobu Railway operates 12 routes in the greater Tokyo area and runs a tourist train pulled by SL Taiju steam locomotives in Tochigi Prefecture. Until now, Tobu Railway ran two steam locomotives, however, to enhance the operation of the popular train, the company decided to restore a museum condition steam locomotive from Hokkaido Prefecture. The restoration was expected to take two years, but the body was more damaged than they had anticipated. Half of the parts, including the boiler, needed to be rebuilt, which in total took three years. See all the work that was done for the first time in 47 years to restore the old iron horse.
