On 31 December 2002, Tube Lines, of which Amey is a 66% shareholder, took over maintenance and upgrade of the infrastructure on the Jubilee, Northern and Piccadilly lines.
Tube Lines has a 30-year Public Private Partnership (PPP) contract with London Underground. The contract is output based; Tube Lines is rewarded for good performance and penalised for poor performance.
Reversing the effects of decades of under-investment in the Tube is a huge task requiring an injection of resources on the scale of which the Underground has never seen before. Tube Lines is involved in a massive improvement programme, tripling investment and committing over £4.4 billion to improve the Jubilee, Northern and Piccadilly lines in the first 7½ years – the equivalent of almost £1.6 million per day. Tube Lines is responsible for:
- Over 200 miles of track
- 255 trains 100 stations
- 2,395 bridges and structures
- 71 lifts and 227 escalators
