It is located between two level crossings (known as East and West) that were previously upgraded in the 1970s. In 2015, Network Rail carried out a further upgrade which saw the control of these level crossings pass from the Grade-II listed Llanelli West signal box (which worked the two crossings here only since 1973) to Port Talbot Panel Signal Box using CCTV.
Llanelli railway station was the scene for the Llanelli Riots of 1911. The Llanelli Riots took place on 19 August 1911. Their immediate cause was the very first railway strike which lasted only two days. The strike started on Thursday evening, and by Saturday evening two young men had been shot dead by the military. One man was killed when a railway truck exploded and, on the following day, three more people died from their injuries. The story of the Riots is set in a period of great industrial unrest, and involves prominent figures on the international scene such as Lloyd George, Winston Churchill, King George V, and Kaiser Wilhelm of Germany.
