橫瀾島
The local signal stations were initially set up in the harbour and the outlying islands. As the population grew after the Second World War, signal stations gradually increased in number across the territory in addition to signal stations at the Hong Kong Observatory Headquarters and outstations at Cheung Chau and Waglan Island. A number of old signal masts in the New Territories and the outlying islands had to be repaired, and several new signal stations were brought into use. Most of the signal stations were located at government buildings of the Hong Kong Police Force and the Marine Department.
