Plans that close on the baseboard

RailSnap joins real track pieces at their connectors, by article number: drop a piece near an open end and it snaps into place. A layout that closes on screen also closes when you build it.

Get RailSnap See how it works

Dragging a curve onto a three-way turnout: the curve turns to match the open end and shows green before it is dropped

What it does

Routes listed between two open ends, with the selected one previewed

Connect two ends

Pick two open ends and the app works out the straights and curves that join them, exact routes first, each with its error.

A bridge over track, with ramps marked as too steep

Heights, slopes, bridges and tunnels

Raise track, grade it into slopes and put it on bridges or in tunnels. The check finds slopes that are too steep and track without enough headroom.

Track with a level crossing, roads and Car System lanes

Streets and the Car System

Plan roads from Faller's Laser-Street, Vollmer's road plates and Noch's road film, with level crossings, stops, branches and sensors.

Light signals and semaphores beside two tracks

Signals and directions

Place Märklin and Trix signals beside the track, and mark which way trains run. The check tells you where trains cannot get back.

The 3D view of a layout with a wall, a rock face and a tunnel

See it in 3D

Turn and zoom the layout on its terrain: slopes, retaining walls, rock faces, bridges on piers and tunnels under hills.

The inventory of owned pieces next to the parts list

Parts list and inventory

Count the pieces a layout needs, by article number. Keep an inventory of what you own and see what is left to buy.

Measure

Tap two points to see how far apart they are, along and across the track, and the angle and difference in height between them.

Made for touch

Drag pieces from the list onto the plan, or tap one to add it at the open end. Tap to select, double-tap to select everything joined, long-press and drag to select a box, and pinch to zoom. Buttons fit a fingertip, and open ends answer a tap that is a little off. A mouse, trackpad and keyboard work as well.

Track and roads

Märklin C and K track, Trix C track, Roco Line track with and without a bed, Roco geoLine, and Piko A track with and without a bed, with Märklin's and Trix's signals; Faller Car System Laser-Street, Vollmer road plates and Noch road film.
