NET is a 32-kilometre-long (20 mi) tramway. The system opened to the public on 9 March 2004 and a second phase, that more than doubled the size of the total system, opened on 25 August 2015.
The tramway is operated and maintained by Nottingham Trams Ltd. on behalf of the Tramlink Nottingham consortium. It was operated by Arrow Light Rail, another consortium from 9 March 2004 until 16 December 2011.
The network consists of two lines that cross the city, running together on a common section for the middle part of their journey, including the city centre section. One line runs between Chilwell and Hucknall, features a total of 33 or 34 tram stops, depending on direction. The other line runs between Clifton and Phoenix Park, features 27 or 28 tram stops, depending on direction.
The system started with fifteen Incentro AT6/5 trams, built by Bombardier Transportation (formerly Adtranz) in Derby. These Trams were all refurbished between 2008 and September 2014. With the two extensions to Beeston and Clifton, 22 new Alstom Citadis 302 trams were purchased, and the first entered passenger service 27 July 2014 bringing the fleet total up to 37.
