This type of junction is only good for lines where you want trains to go one direction only, from a raw material industry to a production industry or a final industry, for example from a Iron Ore Mine to a Steel Mill or from a Coal Mine to a Power Station. Note that a tunnel was used instead of a bridge. This is because tunnels have no maximum speed. Speed is everything so if you have to build a bridge, build the fastest one you can.
- Cheap and easy to build.
- Can handle two trains at a time. (Several without great impact on the main track speed, if built correctly)
- No crossovers - replaced with a tunnel.
- Trains must slow down due to a steep curve. (can be fixed by making the curve loop slightly further)
- Trains go to one direction only
- Trains must turn left to go right
- Tunnel increases minimum train spacing. (Can be fixed by using two or more tunnels)

This version is shown here as alternative, but it is by all means worse. In this version mainlines have tunnels where you cannot place signals.
