New Zealand/Railways

Signalling Systems

There are several signalling and protection systems in use:

Automatic block signaling:
- Centralized traffic control: railway:ctc=yes
- European Train Control System: railway:etcs=1
Dark territory:
- Track Warrant Control: railway:twc=yes

The boards in the next section indicate the start/end of each system.

All signals should have some standard tags which are not included in the tables below:

Ref Plates

	`ref=ISN 4R` `railway:signal:main:function=exit`^[1]^: 20^{[note 6]}

Vertical Alignment

For double signals, the vertical alignment of the two signals indicates whether it's an absolute or permissive signal.^[1]^: 32–33

		Vertically aligned (absolute)	`railway:signal:main:shape=aligned`
		Vertically offset (permissive)	`railway:signal:main:shape=staggered`

Miscellaneous

	Train Ready to Start (TRTS) panel.^[1]^: 103 Typically located on the platform at terminus stations.	`railway=key_switch` `railway:key_switch:departure=NZ:TRTS`
	Not related to signalling. Just a cabinet with a coupling adapter for Matangi EMUs.^[5]	`man_made=street_cabinet` `ref=SD10`
	Milestone marker	`railway=milestone` `railway:position=116`
	Half-milestone marker	`railway=milestone` `railway:position=½`

↑ The bottom unit might be a multi-aspect searchlight unit, or a single-aspect Marker Light
↑ tunnel signals also fall under this category
↑ could also be a ground signal
