An HOn30 model of a General Electric 25-ton industrial 30" narrow gauge locomotive. This model comes in two pieces that snap together. It is designed to fit a Kato 11-103 N scale mechanism. See the photos for more details.
This version comes with pockets for mounting Micro-Trains #1015 N scale knuckle couplers. You will need to remove the ends of the Kato chassis in order for it to fit. A version with hook & loop style couplers is available here.
