0-4-0 Yard Engine

Allen 0-4-0

The 0-4-0 yard Engine was designed by Marty Knox as an entry level engine with a minimum of parts, yet is a powerful puller with more flexibility to operate on home tracks with tight radius curves.  There is a wide range of silhouettes and designs the builder may choose from if he wishes to individualize the basic design.

The engine has all the features that constitute a good functional working model. The boiler is made from a single 8 5/8" diameter steel tube with a minimum number of joints. The large firebox and grate area promotes free steaming, and the cylinder unit is separated into three pieces for easy machining. The smokebox splits on the centerline for accessibility to the internal fittings. The side frames are now also available as a waterjet frame, saving many hours of labor and hardware costs.

We recommend that the builder has a lathe of at least 12" swing and a vertical mill with at least a 36" bed to complete this project.

  3. Y100-2 Pair of Waterjet Frames
    $300.00
    This waterjet frame replaces the built up bar stock frame kit for the yard engine.

The hoops at the bottom of the as-waterjet item are to hold the frame's shape while the pedestal guide surfaces are machined. They are cut off and then the pedestal retainers / keepers installed. When not in stock, These frames are produced to order. Please call us at 775-782-3800 or email us at steve@allenmodels.com to place an order for this item. Learn More
