The North Shore, Northern & Western Line (numbered T1, coloured yellow) is a commuter rail line operated by Sydney Trains in Sydney, New South Wales, Australia. It serves the North Shore, Northern Suburbs and parts of the Inner West and Western Suburbs.

Following victory in the 2011 New South Wales election, the O'Farrell Government embarked on reform of transport in New South Wales. In November 2011, a new organisation, Transport for NSW, was created to improve planning and coordination of transport projects and services. The organisation developed a new rail timetable and branding, which was put into effect on 20 October 2013. This saw the merger of the North Shore Line and Western Line (Berowra - City via Gordon then to Emu Plains or Richmond via Strathfield) with the Northern Line (Hornsby - City via Macquarie Park then to Epping via Strathfield). A new numbering system was also introduced and the line was given the number T1.

The North Shore, Northern & Western Line utilises a number of different railway lines and is the result of various schemes to link the lines together. The line is centred around the Main Suburban railway line which runs from Central to Granville. The Main Northern and Main Western lines branch from the Main Suburban Line. The North Shore Line branches from the Main Northern Line and was later extended through the city and connected to the Main Suburban Line as well. The Epping to Chatswood line provides a second connection between the Main Northern and North Shore lines, enabling the creation of the North Shore, Northern & Western Line's current layout.

The Main Western line opened to Penrith in 1863 as a branch from the junction with the Main South line at Granville. Electrification reached Parramatta in 1928 and Penrith in 1955.
