Arriving at the Kiwi Burn swing bridge terminal, tourists will continue on a mechanical (as opposed to maglev) monorail travelling 35 minutes through high country and native bush for a distance of 41 km, which would be the longest monorail connection in the world, before joining up with a bus park and ride facility on the existing road to Milford Sound north of Te Anau. Three passing loops along the line would allow four trains to run, at speeds of up to 90 km/h. Kiwi Burns Saddle, the highest point of the journey, is 675 m above sea level, and the higher-altitude section of the rail would be heated to prevent snow-buildup in winter. Each monorail train would seat 160 passengers, consisting of 16 articulated 2.6 m wide sections totalling 66 m in length. Only one train would be constructed initially.
