The Edinburgh, Leith and Newhaven Railway was a railway company formed in 1836 to connect the city of Edinburgh with the harbours on the Firth of Forth. When the line connected to Granton, the company name was changed to the Edinburgh, Leith and Granton Railway. It opened part of its route in 1846, but reaching the centre of Edinburgh involved the difficult construction of a long tunnel; this was opened in 1847. It was on a steep incline and was worked by rope haulage.

Trinity Chain Pier, originally called Trinity Pier of Suspension, was built in Trinity, Edinburgh, Scotland in 1821. The pier was designed by Samuel Brown, a pioneer of chains and suspension bridges. It was intended to serve ferry traffic on the routes between Edinburgh and the smaller ports around the Firth of Forth, and was built during a time of rapid technological advance. It was well used for its original purpose for less than twenty years before traffic was attracted to newly developed nearby ports, and it was mainly used for most of its life for sea bathing. It was destroyed by a storm in 1898; a building at the shore end survives, much reconstructed, as a pub and restaurant called the Old Chain Pier.
