As the project progressed, due to financial difficulties both LCR and its subsidiaries underwent various changes in financing, structure and planning, with the government and Railtrack (later Network Rail) becoming involved in the various plans and projects. In 2007, the second stage of the CTRL was finally completed (the CTRL being rebranded at that point as High Speed 1 (HS1)). By 2009 the government had assumed full control of LCR, announcing its intention to privatise it to recoup its investment; this was achieved in two stages, with the 2010 sale of a 30-year concession to own and operate HS1, and the 2015 sale of the British stake in the Eurostar operator (renamed in 2009 to Eurostar International Limited, EIL).
