The spooky abandoned Edinburgh tunnel that runs beneath the Scottish capital

dailyrecord.co.uk:

Whether you live in Edinburgh or just visit the Scottish capital regularly, you may be unaware that there is a massive abandoned train tunnel that runs directly underneath the city.Back in the 1840s, work started on a railway that would create a link between the north of Edinburgh and Canal Street Station — better known today as Edinburgh Waverley.

Construction involved the creation of a major tunnel from Canonmills that ran beneath Scotland Street, Dublin Street, and St Andrew Square.

As reported by Edinburgh Live, the tunnel cost more than £100,000 at the time and was officially opened on May 17, 1847. It allowed passenger trains to travel between Waverley and Granton, though required them to be hauled by a steel rope and winding engine due to the steep incline.In spite of the difficult construction and substantial cost, the kilometre-long Scotland Street Tunnel was deserted after only 21 years of use.

This is because, during that time, the North British Railway company opened a more efficient route that served the northern areas of Edinburgh.A few decades after the tunnel was closed, it saw new life as part of an unexpected business venture.
