Roads and rails

So I have two ideas:
1.roads
Roads can be built inside your territory and units can move a greater distance in roads
2.railways and trains
Railways can be built like roads. Trains are transport ground units that can only move along a railway.
Also maybe bridges? Would be awesome to have bridges

Added 5 days trial premium, this is available in custom scenarios.

Well there is a way to make railways
step 1 : start making the provice
step 2 : Make a 2 edge line of where you want the road/railway to go
step 3 : Make a train or road unit in a special cap (note the train unit has to be sea other or transport to work)
