This is a scale (1/32) model of a Bobber Caboose for a garden railway (runs on 45mm tracks). Cabooses are manned North American railroad cars coupled at the end of a freight train. Early cabooses were named "Way cars". This model with a cupola began its service in the late 1890s. The 2 axles Bobber caboose was known for the uneven ride its lack of trucks created. The model uses 3 mm wheel axles.
