The Obskaya–Bovanenkovo Line is a 572-kilometre long (355 mi) railway line in northern Russia, built and owned and operated by Gazprom. It was opened for traffic in 2010 and was built for the gas fields around Bovanenkovo on the Yamal Peninsula, the Yamal project. In February 2011, it was extended to the Karskaya station, making it 572 km long. Like most railways in the former Russian Empire, it is built to Russian gauge.
