A P&TR passenger service to Carmarthen was started at the beginning of August 1869 and, from then, for a period Tenby had through carriages from Manchester and Liverpool via the Central Wales line, exchanged at Carmarthen. At the end of June 1872, the working contract with Davies and Roberts expired and the P&TR took over the running of its trains. In May 1872, the LNWR published a timetable showing through carriages from Tenby to Euston, running via Shrewsbury and Stafford and in retaliation the GWR announced a Paddington to Pembroke Dock through connection via Gloucester.
