Class B3: Preserved Tobu Steam Locomotive

Steam locomotive unit 34 of the Class Tobu B3 is exhibited in Haginaka public park

Following the preserved old streetcar, 1100 series, I am going to show you the other photographs, which I recently rediscovered on my hard disk.

In October, 2014, I enjoyed walking in the southern part of Tokyo and found an old steam locomotive named Class B3 in Haginaka public park in Ota Ward by chance. It was preserved in good condition under a special roof.

Class B3 was a steam locomotive on the Tobu Railway. It was commissioned in 1911 for freight transportation. A total of 6 units (unit 29 to 34) were built by Beyer, Peacock & Co. Ltd. in Manchester, United Kingdom. It has leading wheels and a tender (4-4-0 in Whyte notation). The driving wheel diameter is 1,372 millimeters and the gauge size is 1,067 millimeters. The greatest feature of this locomotive is its firebox. It is called Belpaire-type. Belpaire was a Belgian steam locomotive engineer, who developed this efficient firebox. It is said that the circulation of boiler water in the Belpaire-type firebox is quite efficient. Brothers of Class Tobu B3 steam locomotive also belonged to Nippon Railway (present JR group). It was called the Class 5600. A total of 18 units (unit 213 - 230) were imported from the United Kingdom between 1899 and 1902.

Class B3 was retired from the track between 1963 and 1966. Two units are still seen in public parks in the Tokyo metropolitan area. Unit 30 is exhibited in Katayama Park in Tochigi Prefecture; meanwhile, unit 34 is in Haginaka Park.
