A turntable was provided at Tenby and two more locomotives were brought in by sea. The customary Board of Trade inspection took place on 24 July 1863 and approval to open was given, and the line opened on 30 July 1863 between Pembroke and Tenby. There were three trains each way daily, increased to five from September, but the service was reduced to three again in December; the line was worked by Davies and Roberts. At first the line was not opened between Pembroke and Pembroke Dock, but this too was completed and opened on 8 August 1864.
