The sharp curves have long hindered high speed operation, contrasting to the Hankyu's other main lines, Kobe and Kyoto.

[citation needed] The Minoo Arima Electric Tramway opened the entire line on 10 March 1910 as 1435mm gauge dual track, electrified at 600 VDC.

Although the line was not a prospect interurban as Takarazuka was not a big city, it saw initial success thanks to the company's aggressive measures.

It strategically developed housing areas along the line for the increasing white-collar population who would commute to central Osaka by train.

As the commuters increased, Hankyu's first 10-car operation began on the Takarazuka Line in March 1982, but 10 car trains were discontinued again in December 2022.
