'''City Direct Services''' (CDS) are express bus services that connect residential estates with the Central Business District (CBD) via expressway, operating during the weekday peak hours in uni-direction. They were introduced under the Bus Service Enhancement Programme (BSEP), offering an alternative travel option for residents travelling to the city. This initiative was in line with the Ministry of Transport’s announcement at the Committee of Supply 2013 to tap on the resources of private bus operators to run more city direct services to augment the resources of the public transport operators (PTOs).<ref>[https://www.mot.gov.sg/news-centre/news/Detail/COS%202013%20-%20Speech%20by%20Transport%20Minister%20Lui%20Tuck%20Yew%20on%20Enhancing%20Public%20Transport/ "COS 2013 - Speech by Transport Minister Lui Tuck Yew on Enhancing Public Transport"]. Ministry of Transport (13 March 2013). Retrieved 28 May 2020.</ref> Four other Express services 513, 850E, 951E and 982E are operated by PTOs that run parallel to train lines between estates and the city.

With limited stops and usage of expressways, commuters using these services would have comparable journey time to taking a connecting bus or Light Rapid Transit (LRT) service and transferring to the Mass Rapid Transit (MRT) into the city. They are scheduled to have at least two one-way departures from the housing estates and city during weekday mornings and evenings respectively. Fares are currently charged based on distance-based fares for express bus services.

All services were initially operated by private bus operators using coaches, providing commuters with a comfortable and direct journey to their destinations. Today, all City Direct services are operated by PTOs using single-deckers and double-deckers.
