Model details
Railway architecture · N 1:160 and H0 1:87 · Development package v0.5
A locomotive depot that can grow with your layout.
This Probstzella-inspired roundhouse is built around a configurable radial plan rather than one fixed footprint. The editable source allows the number of stalls, radius and depth to change. The principal study has ten stalls, while a smaller three-stall roof variant demonstrates a more compact arrangement.
Development preview — not available for purchase. This is a digital architecture and fit-interface study, not a complete, physically tested building kit.
The building and its working spaces
The model includes interpreted internal framing, inspection pits, windows, roof ventilators and static door alternatives. An optional service annex provides workshop, staff and WC spaces. Roof locating features and cable passages are included in the coordinated scale studies.
Board joints, masonry plinths and roof-course relief are modelled in the surfaces. Roof treatments can be changed between small rectangular courses, broad sheet seams and a plain finish. These are reversible modelling interpretations, not confirmed descriptions of the shed’s roofing or cladding in 1930.
What the current development package contains
v0.5 packages the existing v0.4 geometry with an illustrated English assembly guide, numbered model diagrams, a parts inventory and provenance notes. Existing v0.4 labels in CAD views identify that retained geometry; they are not a different product.
- Editable Python architecture in real-world metres.
- Coordinated N and H0 digital assemblies, plus a full-size architectural mesh export.
- Fit and surface-relief STL coupons for future print trials.
- Assembly documentation and recorded digital checks.
Designed alongside a separate turntable
The building and the Configurable Railway Turntable share a rail-head datum and a coordinated track arrangement. The 11.5-degree stall spacing is a deliberate layout adaptation for the companion 16.5-metre bridge, not a newly established historical measurement. The turntable is a separate model, not part of the roundhouse package.
What still needs testing
Complete wall and floor splitting, scale-specific reinforcement, minimum-feature decisions and slicer review remain outstanding. No full physical print or assembly test is recorded for this package. Historical dimensions and concealed construction also retain documented uncertainties.
Digital model previews and setting artwork are not photographs of a finished print. Landscape, track and companion models shown for context do not imply an included scenic kit.
