Public Transport

Independent bike transit away from cars and connecting everywhere. There should not be stops or intersections anywhere. A simple culvert works as an under/over pass. There are several in my area that are just very large corrugated drainage pipes. Without the need to support cars, this stuff is cheap to build by comparison.

I have a few, but a world-wide, interconnected high-speed rail is probably my wettest dream. Imagine taking the a highspeed rail from Paris to Beijing across Europe then the Trans-Asian Railway. Or deciding to travel from Alaska all the way to Patagonia by train. How about a trip from Oslo to Cape Town? We have the technology to make that reality.

My wildest dream though would be having some kind of solution for connecting remote areas. Imagine living in a cabin in the woods and wanting to get to town. Right now, the most likely answer would be "I need a car", but imagine we invented something else? What would that be? A public hydrogen powered drone network for last-k transport maybe? Gondola lifts? Bike paths and on demand rail to every house? A slingshot system with a glider? I dunno, just anything but a car.

Dutch style bike infrastructure in the US.

So this is not my idea. Its been around for awhile. Its actually kind of two but they could be combined. One is to have a one way bike expressway where going out of the city starts high up in the city and its end destination is at ground level and the reverse for going into the city. Every so often there are egress/entrance points with stairs. The idea is that you are riding very slightly downhill. A similar thing is covered bikeways that are one way and completely covered tunnels that have negative pressure so the wind is always at your back. That could have interchanges to switch direction. Also the concept could be combined so your ride into the city is covered, downhill, and with the wind at your back. I can say this. Where I was at biking into the city seemed to be overall slightly downhill and in the morning the wind seemed to mostly be at my back and in the afternoon coming back it was reverse (slightly uphill and wind in face) combine that in the summer with the mornings being cooler and oh man biking in was way easier. I used to bike in and then bring my bike on the train for the way back (which by the way was awesome.)

I wouldn't chew someone's ear off or anything, but I have thought about wormhole portals and trains. Teleporting trains. And you can see through the portals too.

Edit: I realized this is the public transport community, but you said feasible or not and I chose not.

As eventual God Emperor of New Jersey I've given it much thought. It involves light rails, trams (mind the tram car please) and lots of jitneys!

I know it's just a fantasy but having a semi frequent tram on 1 or 2 major routes in the area.

there was this idea for a swiss wide hyperloop like metro: https://swissmetro-ng.org/en/

and more recent one a similar system just for cargo: https://www.cst.ch/en/

Both have enormous potential but ofc also enormous costs. More realistically I would be really happy if we would have a European wide high speed railway. Similar like the Shinkansen, connecting all major cities.

A Vancouver like skytrain - but down every major street, with stops every half mile (my city is laid out on mile grids). These go not downtown, but to the middle of every township (Townships in the US are squares 6 miles on a side) - these trains are really going township to township, but you are mostly expected to ride to the center of your township). From there you can get express trains to every suburb around, and those continue on through the city. All of this frequent so once you arrive it is only a few minutes until the train arrives, and fully automated

Lots of chair lifts in hilly areas. I have ideas to make them bike/handicap accessible.

Honestly extending Dortmunds H-Bahn to the city center. It is completly stupid as there is already an extensive light rail system, which covers every logical approach so well, the H-Bahn is a complete gadget bahn and most stupidly I have never even been to Dortmund. But I like small automated metros and suspended railways are really really cool too. So any system which combines both is just awesome to me.

The Guns Above by Robyn Bennis.

Airships in the Napoleonic Era. The only 'fantasy' element in the book is that they have unlimited access to helium.

Sailboat. But I also want to become liveaboard someday.

I'd like to be able to broadcast/listen to what my fellow passengers are listening to in their Bluetooth headphones.

Hydrogen powered trains, with stations that generate the hydrogen to power them.

Trebuchet to work.

Fewer ferries, more catapults.

My focus is sort of on the other side of all these public transit options - the autoroads changing with disuse, falling into disrepair, perhaps some becoming seasonal. I like thinking about the types of vehicles we might see once nature lowers the the speed limits and people don't have to rely on cars because there are better alternatives like trains and ropeways.

Making fantasy transport networks is one of my favorite hobbies 🙂
I usually try to keep it "realistic", meaning doable with current technology and budgets, taking maximum advantage of existing infrastructure without complete rebuilds.

Make buses a tag on tag off system so that transit agencies have the data about where people are coming from and going, so they can have realistic data to build routes

A series of platforms that can raise on demand. Couple hugs poles around town in clusters of destinations and the tiles would rotate or swap positions to where you are somehow.

A smaller number of much bigger poles with not necessarily bigger platforms that crosses bigger distances at once. Cross country trips would involve several exchanges of platforms, not unlike connecting flights or trains, but it would have a better fuel system.

Maybe a whole third or fourth tier of them for local, regional, interstate, and long distance. I used the word platforms, but given the speed the bigger ones would move at it would probably be more like one of those observation tower-like rides at a theme park. Sometimes you'd stay on the same one as it got picked up by a different tower, sometimes you'd switch.

Not feasible, but a fun idea.

i live in nyc

i would like some more subways that go sideways pls we already have a lot of north south ones

(i still support the Q extension though)
