The latter part of the 19th century marked the modern phase of the development in the history of the Singapore postal service. Services were extended to include a parcel post service, money order and postal order services and a post office savings bank. 1897 saw the establishment of the first sub-post offices, and by 1938, some 20 sub-post offices were already providing decentralised postal facilities on the island. The horse-drawn mail coaches were withdrawn and replaced by motor vans in 1914 as the mail traffic handled steadily increased.
