In, or between? Like your link tells, urban is defined by 2,000 houses. At that scale, in-town transport doesn't really make sense. You can already walk just about everywhere in five minutes. A single train station to get you to other towns makes more sense, but...
- We already had exactly that in the past. Perhaps service ended because nobody wanted to use it? ...
- After all, the town already has the town things. The whole point of living in an urban area is so you can walk to all the things you need on a daily basis. If you are leaving the walkable bubble, you're most likely headed to a rural point to access that which cannot be offered in an urban setting. Transport isn't about where people live, but where they are going.
