One of the most well-known pieces of Swansea's history began life at this stage: the Mumbles Railway. This started in the first decade of the 19th century as an industrial tramway: a horse pulling a cart along tram plates. It had a specific branch line into Clyne valley where Sir John Morris, one of the railway's owners, owned coal mines. Despite some early journeys made by tourists, it was not until the 1860s that the railway began to carry passengers regularly, by which time it had acquired rails instead of tram plates.
