1067 mm gauge, overhead current collection (direct current 1500 V). The Chiyoda-sen runs from 1 Yoyogi Uehara in the west of Tôkyô to 19 Ayase in the north-east of Tôkyô. Length: 21,9 km. The line was opened 1969 – 1978.

The stations are: 1 Yoyogi Uehara 代々木上原 – 2 Yoyogi Kô’en 代々木公園 – 3 Meiji Jingû-mae 明治神宮前 – 4 Omote Sandô 表参道 – 5 Nogisaka 乃木坂 – 6 Akasaka 赤坂 – 7 Kokkkai Gijidô-mae ("In front of the Diet Building") 国会議事堂前 – 8 Kasumigaseki 霞ヶ関  – 9 Hibiya 日比谷 –10  Nijûbashi-mae 二重橋前 – 11 Ôtemachi 大手町 – 12 Shin Ochanomizu 新御茶ノ水 – 13 Yushima 湯島 – 14 Nezu 根津 –15  Sendagi 千駄木 – 16 Nishi Nippori 西日暮里 – 17 Machiya 町屋 – 18 Kita Senju 北千住 – 19 Ayase 綾瀬.

The line that links Ayase to the shed at Kita Ayase (North Ayase) 北綾瀬 was opened to passenger traffic (2,1 km) in 1979 and is operated by a short shuttle train.

Many Chiyoda-sen trains continue beyond their end stop onto other company’s lines, and, conversely, trains of these other companies, work some of the services on the Chiyoda-sen. South-west of Tôkyô at 1 Yoyogi Uehara the Chiyoda-sen is linked to the Odakyû Railway Company, with trains running as far as Isehara (OD) (until 2022 they also worked over the Odakyû Company’s branch to the Tama Centre and Karakida). Also, there are express trains (operated by the Odakyû Railway Company) starting at 18 Kita Senju and running right through over the Chiyoda-sen underground line to Katase Enoshima (EN) and to Hakone Yumoto (HA) (for details see Odakyû Company).

To the north-east of Tôkyô many Chiyoda-sen trains continue from 19 Ayase as stopping services over JR East Japan’s Jôban-sen (JÔ), using the special double-track provided there for trains which are neither accelerated nor express services. They work all the way to Abiko, and during rush hours beyond to Toride, which is the end of JR East Japan’s direct current part of the Jôban-sen (from here on the lines switches to alternating current). Conversely, JR East Japan trains work services on the Chiyoda-sen, and also Odakyû Company trains may be seen, having come via the Chiyoda-sen, on JR East Japan’s Jôban-sen double track for stopping trains. JR East Japan sets may also appear on the Odakyû Railway, having come over the Chiyoda-sen.

The Chiyoda-sen takes its name from Chiyoda ward in central Tôkyô, in which also the Imperial Palace is located.
