Clackmannanshire borders Perth and Kinross, Stirling and Fife. The Ochil Hills lie in the northern part of the area. It mostly comprises a lowland plain, forming the straths of the River Forth and of the River Devon, which joins the Forth near Cambus. In terms of population, it is the smallest council area in mainland Scotland, with a population of 49,000, around half of whom live in the main town, Alloa, which is the administrative centre. The main industries are agriculture, brewing, and formerly coal mining. In 2006, permission was given for a waterfront development of the Docks area of Alloa, which has been in decline since the 1960s. Alloa railway station reopened in May 2008. A new railway line connecting Kincardine and Stirling, reconnecting Alloa to the national rail network for the first time since 1968 was opened to the public. Passenger services only operate towards Stirling.
