Mainline Steam Main Trunk Trekker from Auckland to National Park skirts rock formations typical of the area. The line climbs at mostly 2% for about 30Km from Te Kuiti to Parootarao Tunnel and crosses the first of many viaducts. The line was electrified in the 1980s between Hamilton and Palmerston North.
Mainline Steam Heritage Trust operates steam specials throughout New Zealand from depots in Auckland, Wellington and Christchurch. Each year an inter-island Steam Tour attracts fans from around the world. For more visit www.mainlinesteam.co.nz
