 In about 1925, LMS introduced a switching-out system that could turn the Gaerwen-Holland Arms and Holland Arms-Llangefni sections into one long section.This was of particular advantage in early mornings and evenings, when the only services were on the Amlwch line.The July 1924 timetable showed eight passenger trains each way between Amlwch and Gaerwen, with the Red Wharf Bay railmotor operating to Llangefni three times a day.
