 Finally the Caledonian Railway built a viaduct over the Forth at Alloa, and the Caledonian and the North British Railway (which had taken over the Stirling and Dunfermline Railway) collaborated in operating the new short cut; much passenger and goods traffic ran over the bridge; the route was shared, with each company having running powers over the other's line.All these lines closed in the period following 1950 when rail travel was waning, but the section between Stirling and Alloa has reopened in 2008, and carries a regular passenger service.Dunfermline and Stirling had long been centres of commerce, and of regional government, and of industry.
