 The final section to Amlwch was surveyed by the now Major Rich in January 1867.After remedial work, it opened to passengers throughout on 3 June 1867, although the first freight train to Amlwch was on 10 September 1866, according to Amlwch's first stationmaster, Mr O. Dew.The line had been built single track throughout, with the only run-around loop provided at Amlwch, meaning that trains could not pass each other.
