Editing Centralized traffic control (section)

===New Zealand===
CTC was first installed in New Zealand between [[Taumarunui railway station|Taumarunui]] and [[Okahukura railway station|Okahukura]] on the heavily trafficked [[North Island Main Trunk]] in 1938 followed by [[Te Kuiti railway station|Te Kuiti]]-[[Puketutu railway station|Puketutu]] in 1939.  and from [[Tawa Flat]] to [[Paekākāriki]] on the [[Kapiti Line]] in 1940, and extended from [[Paekākāriki]] to [[Paraparaumu]] in 1943; the continuation of tablet control on the short single-track section would have required manned tablet stations with a stationmaster and three (tablet) porters at each end of the section (see [[North–South Junction]]). This was followed on the NIMT by Puketutu-[[Kopaki railway station|Kopaki]] in 1945, between [[Frankton, Hamilton]] and [[Taumarunui]] from 1954 to 1957; and from [[Te Kauwhata]] to Amokura in 1954.

On other lines, CTC was installed between [[Upper Hutt]] and [[Featherston, New Zealand|Featherston]] in 1955 and between [[St Leonards, Otago|St Leonards]] and [[Oamaru]] in stages from 1955 to 1959. CTC was completed between [[Hamilton, New Zealand|Hamilton]] and Paekākāriki on the NIMT on 12 December 1966. 

On the [[Main South Line]] CTC was installed from [[Rolleston, New Zealand|Rolleston]] to [[Pukeuri]] north of [[Oamaru]] on the [[Main South Line]] in stages from 1969 to completion in February 1980. The older CTC installation from St Leonards to Oamaru was replaced in stages with [[Track Warrant Control]] in 1991 and 1992. 

The most recent installations of CTC were completed in August 2013 on the [[MNPL]] from Marton to Aramoho and from [[Dunedin]] to [[Mosgiel]] and on the [[Dunedin Railways|Taieri Gorge Line]] as far as North Taieri in late 2015.
