Part of the funding will be used to complete the $US 335 million Nairobi commuter rail project which entails construction of a 7km branch to serve Nairobi's Jomo Kenyatta International Airport and upgrading of 160km of metre-gauge lines. Kenya Railway Corporation (KRC) will build four stations on the new and upgraded lines. The project will increase capacity from the current five million passengers a year to 60 million.\r\nIn addition, KRC will carry out feasibility studies for three more commuter rail projects. KRC has already floated an international tender for a feasibility study for the Mombasa Island commuter rail project. This involves upgrading 280km of railway and construction of two lines each 80km long linking Mombasa city with Ramisi and Kilifi. There is also a proposal to build a line from Mombasa to Moi International Airport.\r\nA further commuter rail project is planned to serve the Kisumu region. This entails upgrading four lines totalling 320km. The lines will link Kisumu town with Mumias (70km), Siaya (60km), Fort Tennan (70km), and Kisii (120km). In addition, a 50km line will be constructed from Kisumu to Kakamega.
