Maybe you'll change your decision

For example my situation. Typical chunk sized junction with straight road after.

Would be cool if i could upgrade straight road into junction later, but now i can't because of incompatible signal placement.

1. They are two different rails, so there is no cuting rail into two ...

Currently i'm playing with railroads setups and can't get what is the difference for gameplay is to place signals near each other or 1 tile separated as now?
Game engine, pathfinding, etc. limitations? Or there is another meaning for that?
