The route is from Namba Station in south downtown of Osaka to Wakayamashi Station in Wakayama via Sakai, Izumiōtsu, Kishiwada, Kaizuka, Izumisano, Sennan, Hannan and Misaki municipalities. The proper name is with the company's name, "the Nankai Main Line", not simply "the Main Line" often seen in other Japanese private railways. Lines of the Nankai Main Lane and the connecting lines excluded the Kōya Line and the Airport Line are named generically "the Nankai Line (南海線 Nankai Sen)". The line is shown with a pictogram of waves, or distinguished with blue from conifer or green Kōya Line.

Namba-bound trains are operated every morning and weekday rush hours in the evening.
Semi-Express (準急 Junkū) (SE)

Local (普通 Futsū) (L)
Local trains are operated between Namba and Wakayamashi all day. They also return to Namba at Hagurazaki, Tarui, Misakikōen or Kansai Airport in the rush hours and midnight. Only 1 northbound train is operated from Wakayamashi to Hagurazaki in the midnight. Trains pass Imamiyaebisu and Haginochaya stations due to absence of platforms on the tracks of the Nankai Line. Those stations are served by local trains of the Kōya Line.
In Japanese railway operation, "Futsū" (literally "ordinary, normal") and "Kakueki Teisha" (literally "train that stops at every station", "Kakutei" for short) are used interchangeably for trains that stop at every station. On the Nankai Railway alone, however, the two words are used for different classes of train. The former is for Locals of Nankai Main Line that do not stop at the above two stations, while the latter is for Kōya Line trains that do stop there, true to the meaning of the Japanese name of the service class.

One of the oldest private railway lines still existing, the 2 ft 9 in (838 mm) gauge Namba - Yamatogawa (since closed) section was opened in 1885 by Hankai Railway (阪堺鉄道 Hankai Tetsudō) (separate from the present-day Hankai Tramway).[2] The line was extended to Sakai in 1888, and the Namba - Sumiyoshitaisha section was duplicated in 1892.

In 1897 the then separate Nankai Railway opened the Sakai - Sano (present-day Izumisano) section as 1067mm gauge, with the Namba - Sano section regauged to match, and the Sumiyoshitaisha - Sano section duplicated the same year. The following year the Hankai Co. merged with Nankai Railway, and the line was extended to Wakayama. The present line to Wakayamashi was completed in 1903, and in 1906 the first dining car on a private railway in Japan was introduced on the Wakayama express.

The duplication of the line extended to Hamaderakoen in 1907, Kaizuka in 1911, Takako in 1915 and to Wakayama in 1922.

Electrification at 600 VDC began in 1907 on the section from Namba to Hamaderakōen, and was completed in 1911. The voltage was increased to 1500 VDC in 1973.

Former connecting lines

  • Tengachaya station - A 2 km line to Tennoji opened in 1900. In 1933 the line was electrified at 1500 VDC, the line closing in 1984.
  • Sakai station - A 2km 1435mm gauge line from Shukuin to Ohama, electrified at 600 VDC, opened by the BanSakai Electric Railway Co. in 1912 (and acquired by Nankai in 1914) connected at this station until closed in 1949.
  • Wakayama station - A 3 km line to Higashi-Matsue on the Nankai Kada Line opened in 1912. The line was electrified at 600 VDC in 1930, and closed in 1955.
