Yūbari coalmine, 1912

• Shin-Yūbari station - In 1916, a 7.6 km branch opened from Momijiyama (later Shin-Yūbari) to Noborikawa, approximately on the same alignment as the later Shin-Yūbari - Kami-Ochiai Junction line. It closed in 1980.

Three separate private railways connected to the Yūbari line:

• Numanosawa station - The 4.4 km line to the Hokutan Mayachi coal mine operated from 1913 until the closure of the mine in 1987.
• Shimizusawa station - The Mitsubishi Yūbari line opened to South Yūbari (7.6 km) in 1911, and extended 9.6 km to Sumiyawa in 1929. The Sumiyawa section closed in 1973, and the original 7.6 km section closed in 1987.
• Yūbari station - The Hokkaido Colliery and Steamship Co. built a 34 km line from Kuriyama on the Muroran Main Line (including a bridge over that line) to Yūbari in 1926, including a switch-back (or zig-zag) section at Nishikisawa. A 23 km extension opened from Kuriyama - Nopporo (on the Hakodate Main Line 18 km east of Sapporo) in 1930. At its peak in 1965, the line carried 1.5 million tonnes of coal and another 0.5 million tonnes of general freight annually, as well as 2 million passengers. The entire line closed in 1975 after the closure of the mine in 1972. A 4.7 km branch to the Tsunoda mine operated from 1927 until 1970.

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.[3] The burnt-out train was removed from the tunnel on 29 May 2011.[4]

At around 20:50 on 16 February 2012, a freight train derailed at Higashi-Oiwake Station after passing a signal at red and colliding with the wall of a snow shelter adjacent to the station.[5][6]

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 the delayed down Super Ōzora 13 service to pass 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.[6]
