The Swansea and Mumbles Tramway was initially known as the Oystermouth Railway with earliest passengers carried from 1807 from what is described as "the world's first recorded railway station". It was, though, primarily a railway to transport coal, iron ore and limestone. See https://en.wikipedia.org/wiki/Swansea_and_Mumbles_Railway .  So it feels particularly sad that this historic route was closed to rail on 5th January 1960, with motor buses taking over.  Pictures from that final day at https://www.walesonline.co.uk/lifestyle/nostalgia/rare-photos-showing-final-day-17003953

Apparently, 5TH January 1913, the new Earls Court flyover junction on the London Underground opened.  Evidently it cost £70,000 at the time.
