>>1409853I like to believe that there's a parallel universe somewhere where instead of the interstate system, the government opted to build a 12 foot (144 inch) ultra-broad gauge "landship" rail system across the country. The coaches would be 24 feet across, 36 feet high, and be anywhere from 120 to 180 feet long each with 3 floors, with a garage built into the lowest floor so people could bring their cars on the train. Steam locomotives could be up to 300 feet in length and weigh up to 6000 tons, with up to 8 sets of drivers.
I thought about doing a worldbuilding project about this on DeviantArt but my drawing skills fucking suck.
