There are several private railways in Tokyo, and Tokyu is one of them. It has five major lines and one tramway. While Toyoko Line and Den-en-toshi Line are arterial routes with huge numbers of passengers, Ikegami Line and Tamagawa Line are used mostly for local traffic. Oimachi Line connects several radial lines. Due to infrastructure constraints, only 18-metre vehicles can run on Ikegami Line and Tamagawa Line. Refurbished vehicles are mainly used, but they were to be replaced from 2008.
