Service 50 connects the residential towns of Bishan, Ang Mo Kio, Sengkang and Punggol. It is the fourth bus service to be introduced under the Bus Service Enhancement Programme (BSEP), as well as the first to be dual-depot controlled (Hougang & Ang Mo Kio) and to use BSEP double-deck buses.

The route enhances connectivity particularly within the Punggol and Sengkang areas, where bus connectivity to outlying estates used to be rather limited.

Additional weekday morning peak departures were added from Oasis LRT Station towards Punggol Int from 27 March 2024 to supplement the Punggol East LRT Service from 6:30am to 8:30am on weekdays, except public holidays.
