A march to commemorate the Llanelli riots of 1911 has also been used to demonstrate against proposed changes to health services in the area.
It's the second time the Railway Strike Committee has held an anniversary march. Organisers say they now need to fight another battle for their health service.
Nicola Hendy reports.
It comes after Hwyel Dda Health Board announced plans for possible changes to the NHS in mid and west Wales.
Under the proposals, which are currently out to consultation, Prince Philip Hospital's A&E unit would be reclassified as an 'urgent care centre'.
Hywel Dda's proposals also include the possible closure of three small hospitals. They are Mynydd Mawr hospital at Tumble in Carmarthenshire and Tregaron and Aberaeron hospitals in Ceredigion. All three would be replaced by community resource centres.
A spokesperson for the Hywel Dda Health Board says :
– Spokesperson, Hywel Dda Health Board
We are not planning to remove services from Prince Philip Hospital. Under our preferred consultation option, we will continue to provide care for 100 per cent of patients that should currently attend the hospital in a better way.
This option will see highly skilled emergency nurse practitioners providing care and treatment for minor injuries and illnesses (80 per cent of current activity) through a local accident centre.
Emergency medical patients (20 per cent of current activity) will be admitted directly into the hospital through a consultant-led emergency medical admission unit. These services will be available to the people of Llanelli 24 hours a day, seven days a week.
We propose many other exciting developments and investments for the hospital, including an orthopaedic centre of excellence and short stay unit.
