About
ModuOps (pronounced 'mod-you-ops') is a free, feature-rich desktop application purpose-built for model railroad operations management. Whether you run a Free-mo modular layout, a large club railroad, or a home layout, ModuOps provides all the tools needed to coordinate realistic railroad operations without any coding or technical expertise. The software centers on defining the key elements of your layout: modules and towns, consignees (the businesses that generate freight), drop zones (track segments where cars are spotted), and the equipment needs that drive car assignments. From there, ModuOps generates detailed trainlists — the printed 'scripts' that guide crews through their work — using either random or weighted-random scheduling. Yards serve as the origin and terminus for all trains, and ModuOps tracks storage capacity and expected car types to keep operations realistic. Train definitions include symbols, routes, crew instructions, and termination orders. Modules can be exported and imported as JSON files and shared via a central repository, making it easy to reuse layout segments across different operating sessions or clubs. With a modern, intuitive user interface, ModuOps is accessible to hobbyists and serious operators alike. It is completely free to download and actively maintained, with the current release at version 5.7.1 supporting both Windows and macOS (Intel and Apple Silicon).
Key Features
- Auto-Generated Trainlists: Automatically creates printable crew 'scripts' that guide operators through their work, using random or weighted-random car scheduling.
- Consignees & Drop Zones: Define the businesses that generate freight and the specific track segments — from large sidings to individual warehouse doors — where cars are spotted.
- Flexible Train & Route Definitions: Set train symbols, origins, destinations, lengths, crew instructions, and fine-grained delivery rules for consignees along each route.
- Module Export & Import: Export layout modules as JSON files and share them via a central online repository, making it easy to reuse segments across different sessions or clubs.
- Yard Capacity Management: Track yard storage capacity and expected car types needed to run the layout, ensuring realistic and well-balanced operations.
Use Cases
- A Free-mo modular club uses ModuOps to coordinate multi-crew operating sessions at train shows, printing trainlists so each crew knows exactly which cars to spot at which consignees.
- A home layout owner sets up consignees and drop zones to run realistic point-to-point freight operations with automatically generated switching lists.
- A club layout manager exports modules as JSON files and shares them in the community repository so visiting operators can quickly recreate familiar segments on a new layout.
- An experienced modeler uses weighted random scheduling to ensure that high-priority industries receive more frequent car spots during an operating session.
- A beginner hobbyist sets up a simple home layout in ModuOps and uses the auto-generated trainlists to learn prototype railroad operating procedures.
Pros
- Completely Free: ModuOps is available at no cost for both Windows and macOS, including Apple Silicon support, with no subscription or hidden fees.
- Intuitive Modern Interface: Designed with a clean, modern UI that makes setting up complex layouts straightforward even for non-technical hobbyists.
- Flexible for All Layout Sizes: Works equally well for small home layouts and large modular or club operations, scaling to the complexity of your railroad.
- Shareable Module Repository: JSON-based module export/import and a central online repository make it easy to collaborate and share layout configurations within the community.
Cons
- Highly Niche Application: ModuOps is purpose-built for model railroad operations and has no utility outside of that specific hobby domain.
- Desktop-Only: There is no web or mobile version, so users must be at their Windows or macOS computer to manage or print trainlists.
- Limited Community Resources: As a niche hobby tool, documentation and community support are limited compared to mainstream productivity software.
Frequently Asked Questions
Is ModuOps really free?
Yes, ModuOps is completely free to download and use. There is no subscription, trial period, or paid tier — just download and run it on Windows or macOS.
What types of layouts does ModuOps support?
ModuOps is designed for modular layouts (such as Free-mo), club layouts, and home layouts of all sizes.
What is a trainlist in ModuOps?
A trainlist is a printed 'script' generated by ModuOps that tells a crew exactly which cars to pick up and set out at each location along their route. Crew work can be scheduled randomly or using weighted random selection.
Can I share my layout modules with other users?
Yes. Modules can be exported to a standard JSON format and stored in a central online repository where other users can import them when setting up a new layout.
Which operating systems does ModuOps support?
ModuOps supports Windows, macOS Intel, and macOS Apple Silicon. The current release is version 5.7.1.
