Alright so you know how trains are just a bunch of carts linked together to make one long train?What if the cart at the very end was just like a rollercoster cart, like all the other carts but with the top half cut off and mandatory seat belt and those safety things they have on rollercoasters. It would make train rides ,for those capable to get on, much more fun and it might even attract more people to the trains on a daily basis so the city could make a little bit more off public transport.Of course i got this idea on a high train ride lol
I like your thinking, that would be tight. But it might get boring just going straight for hours at a time lol
