I would think that the clearances around most railways, especially active ones, is such that you can't easily have a side-running railway. Most places, once you turn from parallel to a track to perpendicular-about-to-cross-it, there's a decent gap allowing for you to stop, be blocked by crossing arms, etc. Think of Victoria where you turn up Duke. It's interesting that there are so many crossing arms, which could make it confusing that trains going through some intersections (Erb and Caroline) get them, while others (Charles and Benton) don't.
