Grades and Levels

RailModeller Pro allows you to create complex model railroad layouts in three dimensions. Create grades up to a specified target point or simply by setting the start and end height for a track section.

The optional grade profile view of track elements provides a quick overview taking the hassle out of designing complex layouts with different height levels.

Shopping Lists

A part list is automatically maintained for every layout providing an overview of the tracks used and the overall costs.
Element prices are editable in the part list and RailModeller Pro will maintain a price database making sure costs of elements are kept in synch across all layouts.
