tubeCMS Cameron McKenna has closed the final stages of the London Underground (LU) PPP deal for the Metronet consortium, a key client that the top 20 London firm won in a beauty parade against larger UK rivals.

In a 30-year deal, Metronet will invest $27bn in two of the three infrastructure companies – Infraco BCV (which includes the Bakerloo, Central, Victoria and Waterloo & City underground train lines) and Infraco Sub-Surface (the District, Circle, Metropolitan, Hammersmith & City and East London lines).
