Lines of operation

0 series

Although it can be used on all 1,372 mm gauge lines of Keiō, it is mainly used on the Keiō Line, the Takao Line and the Sagamihara Line.

'0 series' sets are mainly used on Local and Rapid services during daytime. They are also used on 10-car Semi Special Express trains. To create a 10-car train, two Keiō 6000 series cars are added to an eight-car 9000-series train.

30 series

The '30-series' sets are mainly used for through-express services connecting the Keiō Sagamihara Line and the Toei Shinjuku Line, via the inner end of the Keiō Line. Some 30-series sets are rarely used on the section west of Chōfu Station on the Keiō Line.
