Preserved Tobu Steam Locomotive in Miyashiro Town

Tobu B4 Class Unit 40 preserved in front of Miyashiro Town Office

I recently visited Miyashiro Town in Saitama Prefecture, about 50 kilometers north of Tokyo. Miyashiro isn’t very well-known, even among Japanese people. However, if you mention it as “the town of Tobu Zoological Park,” most people will recognize it—or rail enthusiasts may know it better as the home of the Nippon Institute of Technology, which has an industrial museum preserving valuable rolling stock.

This time, though, my destination in Miyashiro was neither the zoo nor the museum. Instead, I headed to the town office. Why? Because a historic steam locomotive is preserved right in front of the town hall. Take a look at the top photo: this is Unit 40 of the Tobu B4 Class. This locomotive was originally built in 1898 by Sharp, Stewart and Company in England for Japan’s first private railway company, Nippon Railway. It was later taken over by the Government Railways in 1906 and then transferred to Tobu Railway in 1922, where it became Unit 40 of the B4 Class.

The B4 Class is a 4-4-0 type (Whyte notation) steam locomotive with a tender. After years of hauling freight trains, it was retired in 1966 and moved to its current location at the Miyashiro Town Office in 1994. I’m not an expert on steam locomotives, but I was especially impressed by its elegant leading wheels and connecting rods (see the photo below).
