Tuen Mun is served extensively by zones 1–3 of the MTR Light Rail (zones 4, 5, 5a are in Yuen Long and Tin Shui Wai), the initial phase of which was completed and operational on 18 September 1988.
The government decided that services between town centres and settlements would be provided solely by a Light Rail Transit (LRT) system, while feeder buses operated by the Kowloon-Canton Railway Corporation (now operated by MTR after the takeover in 2007) would connect remote sites to the network, replacing Kowloon Motor Bus's equivalent services where applicable.
The North-west Railway, as it was then known, was thus established according to the Kowloon-Canton Railway Corporation Ordinance.

The system consisted of two big and three small loops serving most of the public housing estates in northern Tuen Mun.
Three branches: one to On Ting Estate in the southeast, one to the Tuen Mun Ferry Pier in the southwest, and another northern branch all the way into the town of Yuen Long along Castle Peak Road.
