Scrub through four transport eras and watch settlements shift from geographic positions through walking, horse & cart, and railway time-distance layouts.
How it works: Drag the slider to transition through transport eras. Geographic shows true positions. Walking (5 km/h) and Horse & Cart (10 km/h) expand the map to show travel time as distance. Railway (40 km/h) contracts rail-connected settlements together, showing how trains shrank effective distances.
