Building Your Railway Documentation System

Spatial Organization Principles

  • Position modules on an interactive spatial map with anchor-based connections
  • Define rotation angles and lock geometry once placement is verified
  • Create circuit diagrams that overlay physical module positions for wiring clarity
  • Tag scenery checkpoints directly on the map for build progress tracking
  • Log faults with spatial coordinates to eliminate search time during troubleshooting
  • Export complete layouts with all metadata to PDF for offline reference

Rolling Stock Documentation Workflow

  • Create identity cards for each vehicle with photos and service history
  • Record running session routes to understand which locos serve which modules
  • Maintain maintenance logs with timestamps and repair notes
  • Categorize by vehicle type: freight cars, passenger cars, locomotives, equipment
  • Filter inventory by operational status: ready, pending, inspection required

Developer Philosophy

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.


Core Capabilities

Anchor Positioning System

Place modules with precision anchor points that define physical connection locations. Lock rotation and geometry once positioning is verified for permanent reference.

🗺

Interactive Spatial Maps

Visualize your entire layout as a connected spatial network. See module relationships at a glance with 3D isometric views and network diagram overlays.

Circuit Tracing Tools

Document wiring paths with overlay diagrams that show electrical connections across physical modules. Log faults with exact spatial coordinates for rapid diagnosis.

Rolling Stock Cards

Maintain detailed vehicle records with identity numbers, service notes, and operational status. Track which locos run which routes through running session logs.

Module Workshop

Manage modules under construction separately from active layouts. Record dimensions, placement angles, and build stage before integration into the main system.

Local Archive Control

Export complete layouts to local archive files for backup and sharing. Import previously saved archives without cloud accounts or data loss risk.


Technical Foundation

How Turrel Manages Railway Data

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.
