 The LNWR took full advantage of this and by 1873 had secured full access to & control of the Swansea & Carmarthen routes, leaving the L.R with only half its peak track mileage & in such a poor financial position that it was forced to lease its remaining lines to the Great Western Railway the same year.Thereafter the LNWR became the main passenger operator, with the Great Western running just a few trains between Llanelli & Llandovery.In its heyday, the station had four platforms serving trains for the Heart of Wales line as well as trains from Carmarthen via the Llandeilo - Abergwili Jcn branch line (closed in 1963).
