Turrel was built for model railway builders who need professional-grade documentation without cloud dependency. Every feature reflects hands-on workshop experience: from anchor-point precision to offline archive export. The spatial map system mirrors how you actually think about your layout—as connected physical modules, not abstract lists.
Version 1.0 represents a complete documentation toolkit with no account barriers, no subscription walls, and full data ownership through local archive control.
Place modules with precision anchor points that define physical connection locations. Lock rotation and geometry once positioning is verified for permanent reference.
Visualize your entire layout as a connected spatial network. See module relationships at a glance with 3D isometric views and network diagram overlays.
Document wiring paths with overlay diagrams that show electrical connections across physical modules. Log faults with exact spatial coordinates for rapid diagnosis.
Maintain detailed vehicle records with identity numbers, service notes, and operational status. Track which locos run which routes through running session logs.
Manage modules under construction separately from active layouts. Record dimensions, placement angles, and build stage before integration into the main system.
Export complete layouts to local archive files for backup and sharing. Import previously saved archives without cloud accounts or data loss risk.
Turrel organizes your model railway documentation around spatial relationships rather than flat lists. When you position a module on the map, you define its physical dimensions, rotation angle, and anchor points. These anchors represent real connection locations—where one module joins another—creating an accurate digital twin of your physical layout.
The circuit overlay system maps electrical wiring onto this spatial foundation. Instead of maintaining separate wiring diagrams disconnected from module positions, you see circuit paths drawn directly on the module map. When a fault occurs, you log it with spatial coordinates, so troubleshooting means navigating to a map point, not searching through text notes.
Rolling stock documentation integrates with running sessions. When you record a session, Turrel tracks which vehicles ran which routes, building a history of operational patterns. Service notes attach directly to vehicle identity cards, creating a maintenance timeline accessible in seconds.
