"rolling very far unpowered" is like the entire point of rail systems
- RWSen 2y agoExactly. There's a train route here in The Netherlands, from Den Bosch to Utrecht, where the train can coast the last 20 km. That's out of a 48 km trip, so almost half!
- fsckboy 2y agoI would say that's not precisely true. the point of rail systems started out as "big power plant pulls lots of load". Once that was in place, yes, rolling very far unpowered becomes a compelling improvement. a good comparison would be the invention of the travois https://en.wikipedia.org/wiki/Travois https://en.wikipedia.org/wiki/Travois which benefitted from the addition of wheels.
- ianburrell 2y agoRails were invented for horse drawn carts. The low rolling resistance was the point. First steam locomotives were pretty weak and needed the efficiency. They were also used on existing tramways that had to be upgraded as trains got bigger.
