Trainz is a family of railway simulation and route‑creation programs that let users design track layouts, populate them with locomotives and rolling stock, and operate trains in a 3D environment. Originally created by the Australian developer Auran, Trainz has been released in multiple editions and updates over many years, offering both creative tools and driving simulation. For more information see the product page.

Core components and features

Trainz is built around a small set of interlocking modes that separate creation from operation:

  • Surveyor — a route editor for laying track, shaping terrain, placing buildings, signals and scenery, and scripting simple behaviours.
  • Driver — a first‑ or third‑person cab and camera mode used to drive locomotives along routes, observe AI traffic and test operations.
  • Railyard — an asset management area where locomotives, cars and saved consists are stored and organized.
  • Scenarios — mission or task editors that define objectives, timetables and scoring for player challenges.

Beyond these modes, Trainz editions typically include a library of engines and wagons, tools for terrain painting and spline‑based track laying, signaling systems and support for custom content created by users.

History and development

The Trainz series began as a hobbyist‑friendly rail simulator and route editor and expanded into a commercial product line with many subsequent releases. It has evolved to add higher‑resolution graphics, more detailed rolling stock physics, and expanded editing tools while retaining a strong emphasis on user creation. Development has involved multiple releases and community updates; one notable release in the series is "Trainz 12" among others.

Uses, community and extensions

Users employ Trainz for a variety of purposes: hobbyist route building, historical recreations of real rail lines, practising operations and creating scenario-based challenges. A large online community shares custom models, routes and scenarios; many players extend the product with user‑made content, mods and downloadable add‑ons. Trainz has been available on Windows platforms (including legacy support for older systems such as Windows XP and later) and on macOS (with support for versions including Mac OS 10.6.8 and later), depending on edition and release.

Distinctions and notable facts

What distinguishes Trainz is its combined emphasis on both a powerful route editor and an accessible driving experience, allowing creators to both build and test railways in the same product. Its asset library and scenario system encourage imaginative reuse and community sharing. The series has retained popularity among model railroad enthusiasts, modders and players who value editable content and the ability to recreate real or fictional railway operations.
