The line is part of the Seibu Shinjuku group of railway lines that connects suburban areas of western Tokyo to Seibu and JR East main lines that extend to central Tokyo. The line is named after the Tama Lake (多摩湖 Tamako), a major reservoir supplying water to Tokyo, located close to the terminus of the line at Seibu-Yūenchi. Since July 2008, recorded announcements on trains have been provided in English in addition to Japanese and, as part of Seibu Railway's ongoing refurbishment programme, signage and maps at stations are also bilingual.

All services on this line operate as all-stations "Local" (普通列車 futsū-ressha) services, and this line is run mainly as a shuttle service between Hagiyama and Kokubunji stations. The journey takes 7 minutes and is served by two trains running back and forth every 10 minutes between these stations (although services after 10 p.m. are less frequent). The line is single track and except at Hitotsubashi-Gakuen station, Hagiyama station, and a passing place located between Kokubunji and Hitotsubashi-Gakuen stations. Routinely, the services in operation pass each other at Hitotsubashi-Gakuen station, with the first train waiting for the service in the opposite direction to clear the next section of track .
At peak times, a third train is also used on this track section, which usually operates as a through train to/from Seibu-Yūenchi station. This train will pass other services between Kokubunji and Hitotsubashi-Gakuen stations, and at Hitotsubashi-Gakuen station. These additional trains are stored in sidings to the north of Hagiyama station.
Other trains on the Seibu-Yūenchi to Hagiyama section operate as Seibu Shinjuku Line services, which continue past Hagiyama, terminating at Kodaira Station. These services are timed to connect with Kokubunji-bound trains at Hagiyama. At least one Seibu Tamako Line train per hour in both directions operates the full journey between Kokubunji and Seibu Yūenchi. At peak times, some services from Seibu-Yūenchi are coupled at Hagiyama station to trains from Haijima forming Seibu Shinjuku Line express trains to Seibu-Shinjuku.
This line connects the suburban Seibu lines with the JR Chūō line at Kokubunji. At Hagiyama, there is transfer to the Seibu Haijima Line and the Seibu Shinjuku Line. The Seibu Yamaguchi Line, also known as the Leo Liner, connects Seibu Yūenchi Station with Seibu Yūenchi amusement park and the Seibu Dome, home of the Saitama Seibu Lions baseball team. Some passengers alight at Ōmekaidō Station to make the short walk to Shin-Kodaira Station for connecting services on the JR Musashino Line.
The Tamako Line also provides access to the National Center of Neurology and Psychiatry  and the International Campus of Hitotsubashi Gakuen University  from Ōmekaidō and Hitotsubashi-Gakuen stations respectively.
The Tamako Railway opened the Kokubunji to Hagiyama section in 1928, and extended it to Musashi-Yamato in 1930, electrifying the entire section at 600 V DC at the same time. The company was absorbed into the Seibu Railway system on 12 March 1940. In 1961, the line was extended to Seibu-Yūenchi, and the voltage increased to 1,500 V DC at the same time.
