Service 858 is a residential and inter-town route plying between the housing estates of Woodlands, Sembawang, Yishun, and stretching far east to Changi Airport. Much of its route plies express sectors along the Seletar Expressway (SLE), Tampines Expressway (TPE) and Pan-Island Expressway (PIE). At 73.5km long, it is the longest bus route in Singapore (after the shortening of NightRider NR7 in 2014). The ride from Yishun to Changi Airport takes about 38 minutes in smooth traffic.

After 2314hrs to 0030hrs daily, buses leaving Woodlands Temp Int will be renumbered as 858A, and terminate at Yishun Ave 2 (Opp Yishun Stn).

As the quickest transport link from housing estates of the North to Changi Airport, as well as providing valuable inter-town connections in the North, this service encounters moderate to high demand throughout the day. Due to its extended length, bus bunching is relatively common, which BSRF is attempting to minimize.

Changi Airport:

Service 858 serves Changi Airport Terminals 3, 1 & 2 in order.

Changi Airport Passenger Terminal Buildings (PTBs) 1, 2 and 3 have their bus stops integrated into their basement levels, which also serves as a cargo loading and unloading bay. Security checks for any unattended or suspicious articles are carried out before a bus enters Terminals 1, 2 and 3. Bus Captains may take a short toilet break at Terminal 2. Because of height restrictions, double-decker buses are unable to enter Changi Airport basement.

Occasionally when Changi Airport basement is closed, buses will be diverted to to T1/T2/T3 Departure Drive where a temporary bus stop will be set up.

A fleet restriction for Changi Airport appears to be in place, with only Mercedes-Benz Citaro and MAN A24 buses deployed on airport-plying bus services. Announcements for passengers to inform the Bus Captain if they see any suspicious person or article are played on board public buses at Changi Airport as well.
