Wellington, the capital city of New Zealand, has the countrys' best transit facilities, however it is the second largest city after Auckland. New Zealand's transit operations comprise of buses, and Trolleybuses now contracted out to the British Stagecoach Company, but previously operated by the Wellington City Council. Wellington currently has New Zealand's only electric suburban rail network, with 2 main lines (Paraparaumu, on the North Island Main Trunk), Upper Hutt (on the Masterton Line) and the original main North Line via Johnsonville. The Upper Hutt line also has branch from Petone to Melling which has a peak hour only service. All services on this line are operated by the fleet of English Electric EMU's that have been around since electification of this line in 1938. While most have had several refurbishments, a few sets still operate in the old NZR red colour scheme. The unrefurbished sets also supplement the Hungarian built Ganz-Mavag EMU's on peak hour services on the other lines to Paraparaumu, Upper Hutt & the peak hour only served Melling line. The main reason these sets have survived as long as they have is the low clearance restrictions on the Johnsonville Line tunnels and the inability of the Ganz-Mavag sets to pass through a number of them. These services are provided by New Zealand's National Rail Service, TranzRail now a division of the Wisconsin Central Railroad. It was formerly operated by CityRail, a division of New Zealand Railways. The re-organisation of the buses happened in 1993, while the rail sell-off happened in 1995.
