All the exaples below have the basic signaling shown on the images, better signalling positions can improve their preformance if nessesary.

Y Junctions

Y-Junctions act as a convergence or divergence points between two routes on a railway line. Simple solutions tend to work well, but tend to have significant drawbacks when used at high capacity.

Image	Name	Information	Signalling Complexity	No. of Points	No. of Crossings
	Single Track Junction	The most basic junction possible in the game	Low	1	0
	Single Track Junction with passing loop	A more advanced junction with space to allow trains to pass.	Medium	3	0
	Branchline with Ladder Junction	A basic junction from double track to a 2 way single track line. Only one locomotive can use the Branchline	Low	3	1
	Branchline with double track entrance	A advance junction from double track to a 2 way single track line. Multiple trains can use the branchline.	Low	3	1
	Mainline Split	A basic junction for splitting a double track mainline into two directions. Flow is restricted to 1 train accross the junction even if two trains accessing the junction do not cross each others paths.	Low	2	1
	Mainline Continuous Flow Junction	A advanced mainline junction which poses no restriction on the flow of trains.	Low	2	0

Crossings

These are for locations on the tracks where two lines must cross over each other, with no tracked connection between the two.

Image	Name	Information	Signalling Complexity	No. of Points	No. of Crossings
	Crossing on the Level	A simple method for two mainlines to cross, Flow is restricted to 1 train accross the junction even if two trains accessing the junction do not cross each others paths.	Low	0	4
	Overpass	Using bridges to cross other tracks, top line must be perpendicular to the grid, lower lines can be in any orientation. Minimum hight difference of 3 between the two lines.	None	0	0
	Underpass	Using Tunnels to cross under other tracks, bottom line must be perpendicular to the grid, top lines may be in any orientation. Minimum hight difference of 3 between the two lines.	None	0	0

Terminus Junctions

These are a selection of junctions that go at the end of a railway line, these are designed for both high capacity and the ability to turn the trains around to prevent the locomotives from reversing on their return journey. The max number of trains refers the number of trains can use the station without a risk of causing a blockage. All stations below can have their capacity increased by placing block signals.

Image	Name	Information	Signalling Complexity	Max No. of trains	No. of Points	No. of Crossings
	Return Loop	A simple method of turning around trains at the end of the line.	Low	2	1	0
	Turning Triangle	An alternative method of turning around trains at the end of the line.	Medium	2	3	0
	Roundabout	An advanced version of the return loop, this version allows multiple lines to feed into a single station. One way signals must be used to allow for continuous flow.	High	n	3 x n	0
	Main Terminus	A high capacity railway station that works with a continuous supply of trains. There is no reversing facilities, therefore best used when reversing trains are disabled. Further signaling can be added to increase the capacity of the Station beyond a 3 train limit.	Medium	3	7	2
	Main Terminus with Turning Triangle	A variation of the Terminus station with reversing facilities. Further signaling can be added to increase the capacity of the Station beyond a 3 train limit.	High	3	8	2
