User:Timitry/3-Way Junction with 2-Track Mainline and 1-Track Sideline
This junction is used to connect a single-track sideline (one track in each direction), coming from the south-east, to a double-track mainline (two tracks in each direction).
Trains can go from each line to each other line, and the doubled bridges will prevent jams. However, the narrowest curves are only 2,5 tiles long, so you might need to widen the whole junction a bit in order for longer & faster trains to use it. The current setup also lacks any kind of load balancing and priorities, which might be useful for high traffic density.
