The Edinburgh Suburban and South Side Junction Railway (also known as the Edinburgh South Suburban Railway or, more colloquially, the SouthSub) is a freight and former commuter railway which runs in a loop across the southern suburbs of Edinburgh, Scotland. It opened in 1884 for both freight and passenger services. Passenger services were withdrawn in September 1962. A proposal has been put forward by a campaigning group for the line to be re-opened to passenger transport.
