Rack Railways

Real mountain rack railways rebuilt from OpenStreetMap and survey heights, to drive at model scale: each line on its own page, with its trains, its points, the map, the seasons and the cab ride. The workshop holds the working-model kits, and How it works explains the rack railway itself.

How it works

TechnologyRack railway technologyThe people, the racks, how the pinion meshes, entering the rack, the points, the boilers, the descent and the lines: nine chapters with working models you can try.
