As railways are not a usual thing to me (there is VLT in Rio de Janeiro city since this year, but I did not go there yet), I have some doubts about using this tag in my maps.
I am imagining a rail route between Slovech - or Trindade - and Tarugo or Nova Baltimore. Because Slovech is the capital, and Tarugo I will build some important naval and heavy industries. If I create this route, it can be extended to Nova Baltimore, capital of province, just few kilometeres south to Tarugo.
First doubt: Could I use railway=light_rail?? I read in OSM Wiki light rail is a urban trnasport... this way, it would not be the best railway between these cities...
Second doubt: The terminus in Slovech area.
can be in Trindade, a town I will re-map when I finish detailing Slovech. I prefer this idea, but "the passengers" would need to use another transportation (tram and buses) to follow to Slovech
can be in Sant Theo, east Slovech. In fact, here there is integration to other transportations, as buses and trams, and here is some kind of "metropolitan terminus" - the bus routes from Trindade will stop here, only one or two will follow to Slovech downtown.
*can be in Slovech downtown... only if I can use tunnels, because seting so many buildings in Slovech, there is no space to new rail stations. Which railway= I can use with tunnels??
For now I am still with a lot of work to do in Slovech detailings, but, as I am also focused about creating correct relations to all my transport routes, I need to think about it too...
