The Innocent Railway Tunnel is a historic railway tunnel in Edinburgh, Scotland, that was first opened in 1831. It was the first railway tunnel in Scotland and the first railway station in Edinburgh. The tunnel was used to transport coal from the coal pits of Midlothian to the city, and it was initially horse-drawn before being converted to steam locomotives. The tunnel is now part of the National Cycle Network and is open to the public for cycling and walking. It is located under Holyrood Park and runs from St Leonard's to Duddingston and beyond. The tunnel is approximately 518 meters long and is known for its steep incline and historical significance as Edinburgh's first railway line.
