 Having lost their source of finance and project management, the Llanelly company proceeded with the Swansea and Carmarthen lines themselves, running into considerable practical and financial difficulties from landowners and otherwise in the process.The Central Wales Extension Railway was naturally keen for the lines to be completed, and it facilitated friendly contact with the London and North Western Railway and the Llanelly company; could not the LNWR finance the new railways; in fact would not full amalgamation be desirable?Proposals were worked up for a new line from Pontardulais to Swansea, taking a southern sweep through Dunvant, where there were said to be extensive unworked coal measures.
