The Enshū Railway Line, officially the Railway Line (鉄道線, Tetsudō-sen), is a Japanese railway line in Shizuoka Prefecture, running north from Shin-Hamamatsu Station in Chūō Ward to Nishi-Kajima Station in Tenryū Ward, all within Hamamatsu.

The line is nicknamed the Nishi-Kajima Line (西鹿島線, Nishi-Kajima-sen), while locals often call it Akaden (あかでん, "The Red Train"), referring to the color of the EMUs.

The voltage was increased to 750 VDC in 1961, and CTC signalling was commissioned between Nishi-Kajima and Hachiman in 1967, and extended to Shin-Hamamatsu in 1974.
