Everything you need to build your railway

From the first sketch to a detailed 3D layout with scenery, and everything in between.

Controls that get out of the way

Drag track straight onto your virtual baseboard and click the pieces together. Move or turn whole sections, and bend flexible track exactly the way you want it. Context menus show you at a glance what you can do where you are.

A full 3D editor

Not merely a viewer that shows your design in perspective, but an editor built from the ground up for working in three dimensions. Rather work in 2D for a while? Switch back and forth whenever it suits you.

100+ track libraries

Design your dream layout with the track of your favourite make. Mix and match without limits: take the best turnouts from one brand and combine them with the finest flexible track from another, in one design.

The canvas

Lay a photo or a drawing of a track plan on your table, or a blank white canvas, and draw on it: pencil, ink pen, fill, spray can and eraser, lines, rectangles and shapes. Move, turn and scale it to its real size against a ruler; it follows the landscape and is saved with your layout.

Realistic scenery

Finish your layout with mountains, buildings, roads, trees and grass, all of it rendered for real. You can even watch the trees and the grass move in the wind.

Bridges and tunnels by themselves

Mark a stretch of track as a bridge or a tunnel and TRAX builds the rest: the bridge with its spans, piers and abutments, the tunnel portals at every mouth, and the ground around them shaped to fit.

Overhead line, signals and boards

Choose a country and an era, and TRAX places the overhead line, the signals and the lineside boards in that railway's own style: masts and portals along the electrified track, a signal at every block, boards where they belong.

Smart design help (CAD mode)

Let the computer check that your design adds up. Stop a big locomotive getting stuck in a tunnel later, or a curve being too tight. TRAX keeps an eye on whether your layout meets the main NEM and NMRA standards.

A building plan of your own layout

From your design TRAX makes a building plan to work from: the benchwork with every part to cut, the roadbed, the wiring, the blocks and the signals, with a parts list and the drawings to scale.
