The line is a part of the main line between Sapporo and eastern Hokkaido. Super Ōzora limited express trains run between Sapporo and Kushiro 7 times a day, while Super Tokachi runs twice daily, Tokachi 4 times daily, both between Sapporo and Obihiro. The Marimo sleeping car service which formerly operated between Sapporo and Kushiro, was discontinued in 2008.
There are no local train services between Shin-Yūbari and Shintoku, since the line runs through practically unpopulated areas. There is a local train service between Minami-Chitose and Yūbari (via Shin-Yūbari), with one train approximately every 2 hours.

In 1892, the Hokkaido Colliery and Railway Company opened the Yūbari Line (夕張線 Yūbari-sen ) from Oiwake to Yūbari for transporting coal.
In the late 20th century, a plan was proposed to make a line between Shin-Yūbari (on the Yūbari Line) and Shintoku (on the Nemuro Main Line) as a shortcut line between central and eastern Hokkaido. The new line was completed in 1981, becoming the Sekishō Line. The Yūbari Line was split into two sections, the section between Oiwake and Shin-Yūbari being incorporated into the main Sekishō Line, and the section between Shin-Yūbari and Yūbari becoming the Yūbari Branch Line of the Sekishō Line. The new line shortened the main route to eastern Hokkaido. Previously, passengers had to travel via Takikawa or Asahikawa.
2011 Super Ōzora derailment and fire
On 27 May 2011, the Super Ōzora 14 service from Kushiro to Sapporo was brought to an emergency stop inside the 685 metre-long No. 1 Niniu Tunnel in Shimukappu, Hokkaidō, at around 21:55 after car number 2 of the 6-car formation became derailed. The train caught fire, and all of the 245 people on board, including train staff eventually evacuated the train. 39 were treated for smoke inhalation and minor burn injuries. The burnt-out train was removed from the tunnel on 29 May 2011.
2012 Higashi-Oiwake Station derailment
The up container freight train from Kushiro Freight Terminal to Sapporo Freight Terminal was normally scheduled to pass Higashi-Oiwake Station non-stop, but on this occasion faced a red signal to allow it to pass the delayed down Super Ōzora 13 service in the opposite direction. The driver reportedly applied the brakes, but the train failed to stop and was derailed by the catch points protecting the single-track line, hitting the wall of a snow shelter protecting the junction. The JR Freight Class DF200 diesel locomotive and four of the container wagons in the train were derailed, but the lone 25-year-old driver was uninjured. Six train services were cancelled as a result.
