Gaerwen was an intermediate station between Bangor and Holyhead, and junction for the branch to Llangefni and Amlwch. The station was closed in the mid-sixties, but unlike Llanfair and Valley which closed on the same day, it has not been re-opened. However, both the branch line and the freight yard remained open - the latter for coal and fertiliser traffic well into the 1980s.
