In October 2018, Greenbrier and Saudi Railway Company (SAR) announced that they signed an agreement under which the parties will invest and generate investments totaling 1 billion Saudi riyals (US$270 million) in the Saudi rail industry. Through the joint venture, Greenbrier and SAR will establish a new multi-modal business centered on creating and maximizing existing and new rail routes for freight movement throughout the Kingdom and, ultimately, the Gulf Cooperation Council (GCC) region. The relationship between the companies began in 2015 when Greenbrier was awarded a contract with the Public Investment Fund (PIF) to manufacture nearly 1,200 tank wagons for SAR.
