A self-building two lane railsystem with several modular pieces,
- Straight Rail Set
- 90 Degree Curve
- T - Junction
- 4 - Way Junction
- Station for Personal Transport
- Exit from lanes
- Entrance into Lanes
- 6 - Train-Wagon Parking
- 4 Train-Wagon Loading Station (use Constant Combinator to set filters on Filter inserters)
- No Unloading Station yet, I suggest looking at KatherineofSky's Google Drive, she has a great one.
The whole system is selfbuilding, meaning you only have to lay down the Blueprint GHosts and Construction Bots will do the rest for you. It has Radars to scan the area and allow you to observe the rails. Laser Turrets to defend it against biters. And of course Robo Ports along the way so it can repair itself and build itself. The Straight Rail Module has a buffer chest with all neccesary items requested to shorten repair times.
For best efficiency place occasional Buffer Chests along the way to be filled with rails, signals, large powerpoles, laser turrets.

Update: - Added Laser Turrets to 4-Way Junction
