H0 scale locomotive shed for model train

Purpose

This is a detailed 3D-printable model of a classic brick locomotive shed (engine house), designed for HO scale (1:87) model railroad layouts. The design features realistic brick textures, arched multi-pane windows, double swinging entrance doors, rooftop ventilation lanterns, and chimney stacks for smoke exhaust. At approximately 34 cm long, it easily accommodates longer tender locomotives.

Prototype

The design follows the primary architectural elements of Era II–III locomotive engine houses.

Print Settings

• Quality -> Wall Generator: Arachne (essential for printing thin lines and fine details)

• Supports / AMS: No supports or AMS required.

The Kit

The kit includes two ZIP files:

• AG H0 013 all components by type.zip: Contains STL files for all unique parts organized by main model component type (no duplicate parts). File names indicate where each part goes and how many copies to print.

• AG H0 013 all components by tray.zip: Contains STL files organized on build plates/trays with all necessary components grouped by main section.

Main Sections of the Model

• Left Side Walls: Contains the 4 walls and windows for the left side of the model.

• Right Side Walls: Contains the 4 walls and windows for the right side of the model.

• Front Wall with Gate: The front wall along with the swinging door parts.

• Internal Structural Inserts: These extended insert components provide stability for the walls, while the roof inserts help position and support the roof. The 4 step pieces keep the track centered; glue them opposite each other at ground level—one pair near the entrance door and the other pair near the back wall.

• Roof: Contains the 4 roof panels, which are held together by roof inserts that help align them against the walls. You can either glue the roof sections in place or leave the roof removable. The roof trim attaches to the front edge of the roof (you may need to trim it to size).

• Roof Ventilators: Contains all the parts needed to assemble the 2 rooftop monitor windows. The trim base provides a level surface for attaching the roof trim.

• Chimneys: Components to build the 4 chimneys.

• Alternative Elements Folder: Contains an alternative solid back wall (without a window) and alternative side wall options with windows.

Dimensions

• Width: 100 mm

• Depth: 340 mm

• Height: 120 mm

Assembly Instructions

1. Once all parts are printed, you can paint them prior to final assembly if desired.

2. Assemble the front door and fit it to the front wall. Some light sanding/fitting on the wall may be required to allow the door to open fully to 90 degrees.

3. Glue the side wall sections together.

4. Glue the windows in place.

5. Once the side walls are rigid enough, assemble all four walls using the wall inserts to align and stabilize the structure.

6. Glue in the track-centering steps.

7. Glue the roof panels together using the roof inserts for support.

8. Assemble the ventilator windows and attach them to the roof sections.

9. Attach the chimneys.

Note:

I hope the October 23, 2026 update addresses all previous comments and requests! The model itself remains unchanged, but the files have been reorganized to make printing and assembly much easier.

All components are human created however the thumbnails and some of the images are AI generated.
