In rail transport, a train is a vehicle or (more frequently) a string of vehicles capable of being moved along a continuous line of rails or other guideway for the purpose of conveying freight or passengers between points on a predetermined route. The train may be hauled or propelled by one or more vehicles designed exclusively for that purpose (locomotives) or may be driven by a number of motors incorporated in all or several of the vehicles (multiple units).
As of 2017[update], there are approximately 1,051,767.605 kilometres (653,538.091 mi) of railway track in use worldwide. (World Bank)
The North Island Main Trunk (NIMT) is the 682-kilometre long (424 mi) main railway line in the North Island of New Zealand, connecting the capital city Wellington with the country's largest city, Auckland. Most of the NIMT is single track with frequent passing loops, built to the New Zealand track gauge of 1,067 mm (3 ft 6 in). The line is mostly double track, and around 460 kilometres (290 mi) (approximately 65%) of the line is electrified in three separate sections. The first section of what became the NIMT opened in 1873 in Auckland. Construction at the Wellington end began in 1885. The line was completed in 1908 and was fully operational by 1909. It is credited for having been an economic lifeline for the young nation, and for having opened up the centre of the North Island to European settlement and investment. The NIMT has been described as an "engineering miracle", with numerous engineering feats such as viaducts, tunnels and a spiral built to overcome large elevation differences with grades suitable for steam engines.
...that after plans were formed for an Amsterdam Metro line to IJburg, a short tunnel was constructed eastwards from Centraal Station; but when the plans changed, the tunnel was abandoned and may be repurposed as part of a chocolate museum?
