RAD, the Railway Alignment Designer
A browser-based railway design tool that routes corridors, checks alignment geometry, and produces preliminary plan, profile, yard, and CAD-sheet outputs.
Field notes
RAD presents preliminary railway alignment as a browser workflow rather than a sequence of separate drafting tasks. Its stated sequence starts with two map pins, applies 30 m terrain data and alignment rules, then exposes editable geometry and exports such as DXF, LandXML, Excel, and KML. The page also includes a 22-error demonstration and corridor examples ranging from a 250 m urban-transit case to a 7,500 m-radius high-speed mainline, giving visitors concrete scenarios to inspect.
