Early in the 1900's the transportation needs in the Japanese forestry industry required small steam locomotives. A new US built Tank locomotive was introduced by Baldwin of Philadelphia. Originally produced for agricultural duty, these 0-4-2 locomotives came soon into service with the Tsugaru logging railways in 1906. The Kiso Forestry Railways also purchased several of these adaptable B1 tank engines and operated them until the early 1960's , when they where replaced by Diesels. The prototype of this later version Baldwin B1 is still preserved in operational condition.

Aster Hobby Japan has chosen to model this locomotive primarily for their domestic market. A total of 125 examples will be produced. This version is a complete re design of the Baldwin Tank plantation locomotive produced by Aster in 1981. It is available as basic version with slip eccentric reversing gear and limited cosmetic detail. A optional Stephenson reversing gear conversion kit and cosmetic detail kit will be available at additional cost by January 2010. (Optional detail and valve gear kit not available separate).
