Valley Locomotive Works

Valley Locomotive Works is a division of Scale Brass Mechanic that provides unique HOn3 locomotives using 3D printing technology and tried and true Kato mechanisms. All custom mechanical and electrical work is done by Scale Brass Mechanic. All 3D design and printed parts provided by Ride Trains.

The Alco DL535 kit includes a Kato RSD4/5 mechanism that has been expertly converted to HOn3 and thoroughly tested.


The GE C-90 includes a Kato NW2 mechanism with new HOn3 three axle trucks.


Body shell is undecorated but fits neatly onto the Kato chassis, providing a near Ready-to-run experience. Your HOn3 locomotive will run as well as a Kato because it is one.

Kato drive narrowed to HOn3 gauge.  HO standard Gauge available upon request
