Map of US train system in 1890 and today.
@petergleick Passenger trains, one assumes. I imagine the freight network has a lot more in common with the red spiderweb in the first image.
As @pjohanneson guesses the overall network is denser but very little is used for passenger traffic. I also suspect that the “capillaries” of sidings and short lines weren’t visible in the older map and are largely gone today. Map from @openrailwaymap

@rmartinnielsen @openrailwaymap @petergleick The times I've traveled on Via in Canada, one major component of the experience was waiting for not-insignificant chunks of time for a freight train to pass so that we could continue.
