Quay Valley, California
In March 2015, Dirk Ahlborn, the CEO of Hyperloop Transportation Technologies (HTT) in El Segundo, California announced a plan to build a hyperloop test system at the Quay Valley site. Ahlborn indicated that construction could begin in 2016 to be completed in 2017 with the first rides to begin in 2018 if his company can raise $100 million in funding. The company has said that this track will be a fully working and operational creation of the hyperloop, but that running speed will be reduced on the shortened track from Hyperloop's full potential. It is not decided whether a 5-mile loop or straight section will be constructed, and it may cross the Interstate bisecting the site. Ahlborn said that speeds up to may be possible. Quay Hays expects to break ground on the new community in 2016, including a working version of the Hyperloop, estimated to cost $100–150 million.
New Tube for London
In early 2014 the Bakerloo, Piccadilly, Central and Waterloo & City line rolling stock replacement project was renamed "New Tube for London" (NTfL) and moved from its feasibility stage to the design and specification stage. The study had shown that, for new generation trains and re-signalling:
The project is estimated to cost £16.42 billion (£9.86 bn at 2013 prices). A notice was published on 28 February 2014 in the Official Journal of the European Union asking for expressions of interest in building the trains. On 9 October 2014 Transport for London (TfL) published a shortlist of those (Alstom, Siemens, Hitachi, CAF and Bombardier) who had expressed an interest in supplying 250 trains for between £1.0 billion and £2.5 billion, and on the same day opened an exhibition with a design by PriestmanGoode. The fully automated trains may be able to run without drivers, but the ASLEF and RMT trade unions that represent the drivers strongly oppose this, saying it would affect safety. The Invitation to Tender for the trains was issued in January 2016 with the first train to run on the Piccadilly line in 2023.
