Service 851 is an inter-town route serving between the housing estates of Yishun, Ang Mo Kio, Marymount, Thomson, Bukit Merah and Tiong Bahru with connections to the City areas, namely Chinatown, Bras Basah and Rochor Canal. The route is frequented as a popular connection between various housing estates, as well as between housing estates and the City. As such, it benefits from high demand throughout the day, with high capacity articulated buses deployed on a daily basis.
The route shares its popular Tiong Bahru – Bras Basah connection with Service 33, but is otherwise non-duplicative from the City to the North. It also shares long duplicating sectors with Service 852 and 853/# between Yishun – Marymount and Yishun – Ang Mo Kio respectively.
Introduced in 1985 by Trans-Island, the route has not undergone any amendments since.
