Lyttelton Line

Lyttelton Line is a name sometimes used to refer to the section of the Main South Line in New Zealand's South Island between Lyttelton and Christchurch, and can also be used to refer to the operations on this section. As it has always been part of the Main South Line (originally the Canterbury Great Southern Railway), this name has never been officially used to refer to the track itself.The line between Lyttelton and Christchurch is notable for several reasons, including: incorporating part of the first public railway in New Zealand, between Ferrymead and Christchurch; including in its route the still operational first railway tunnel in New Zealand; and, having been the site of the first electrified suburban service in New Zealand.HistoryPart of the Lyttelton Line was originally operated as New Zealand’s first public railway, connecting the city of Christchurch to a wharf at Ferrymead. Because of the inaccessibility of the harbour at Lyttelton, shipping traffic berthed at the Ferrymead wharf from which people and supplies were transported to Christchurch by train. The construction of such a long and expensive tunnel and line in was controversial in the 1850s and 1860s, see William Moorhouse. Following the opening of the Lyttelton rail tunnel on 9 December 1867, the portion of the line from the main line to the wharf reverted to branch line status, but quickly lost its traffic to the line through to Lyttelton and became a siding after July 1868.As with other railway lines then under construction by the Canterbury Provincial Council, the line and the tunnel were constructed to accommodate rolling stock at the behest of contractors Holmes & Richardson of Melbourne, as this was the gauge they were already working with in Victoria. The line remained this way until, following the abolition of provincial government in New Zealand and the establishment of a new uniform national track gauge, the line was converted to by April 1876. Double-tracking of the line was completed as far as Heathcote in 1878. Though NZR considered duplicating the Lyttelton tunnel in 1914, this never went ahead.
