The Northern Line is part of the metropolitan rail network in Sydney known as CityRail, running between North Sydney and Hornsby via Strathfield and Central. It is part of the Main Northern Line, and serves suburbs in the Inner West, Lower North Shore and Hills District areas, crossing the Parramatta River between Rhodes and Meadowbank. It is denoted as red on CityRail network maps and other publicity.
The Northern Line is the suburban portion of the Main Northern Line which opened in as a single track line 1886. In 1892, the line was duplicated to Hornsby1, and electrified in 1926 as part of the Bradfield electrification scheme.
Line Description
Diagram of the Northern Line
The Northern Line crosses the Parramatta River at Meadowbank. Here, the old railway bridge has been converted to a cycleway.
The line physically begins at Strathfield where it branches from the South and Western Lines. The line that CityRail markets as the 'Northern Line' is the suburban section of the Main North Line which heads north to Newcastle and beyond. Train services that serve the Northern Line usually begin as a continuation of North Shore Line services in the north of Sydney at North Sydney station before heading across the Harbour Bridge and through the underground stations of Wynyard and Town Hall to Central and Redfern stations. Services then run along the Main Suburban Railway, usually using the inner 'Suburban' pair of the six tracks between Redfern and Strathfield. Services generally do not stop at intermediate stations between these two points. At Strathfield, trains usually head onto a flyover over the 'Main lines', before going over a bridge across Parramatta Road heading north on their own alignment.
The line between Strathfield and Hornsby is mostly double track, except for quadruple track sections between Thornleigh and Pennant Hills, and between Epping and West Ryde, and triple track sections at Thornleigh, Epping, and between Rhodes and Strathfield. A fourth track existed for freight between Concord West and Strathfield, although this has not been in use since around 2003. The line and stations are all at ground level or in cuttings.
As the line is the main railway heading north to Newcastle, the Hunter Valley, the North Coast, and Brisbane, CountryLink trains transit the line, as well as numerous freight trains. Although there used to be many sidings and freight yards along the line, these have all been removed except for the Gonarro sidings at Thornleigh.
Future
This article or section contains information about a planned or expected future railway station.
It may contain information of a speculative nature and the content may change dramatically as the construction and/or completion of the railway station approaches, and more information becomes available.
Diagram of the new Northern Line after the construction of Epping to Chatswood Line is complete. The line is marked in red.
The line route, which has not been altered since the construction of the Sydney Harbour Bridge in 1932, is set to be changed significantly following the construction of the Epping to Chatswood link, due to open in early 2009.2 Following this, the line will essentially be split in half. Services north of Epping will be diverted to run via the new line and the North Shore Line to free up much-needed space on the lines between Strathfield and Central. Services south of Epping will continue to use the existing route. The only trains likely to continue to use the whole existing route between Hornsby and Strathfield will be the express Intercity services on the Newcastle and Central Coast Line which share the same tracks.

More services serve the line in the Monday to Friday morning and evening peak hour services, where some services omit stops.
All services depart from Hornsby & Eastwood (which is being used temporarily as a terminating station while the Epping to Chatswood Line is under construction.)
During the daytime off peak & weekend daytime, almost all services terminate at Lindfield with some terminate at North Sydney (and will be the case until the ECRL is integrated into the network in early 2009).
During the AM peak, most services continue to Hornsby for daytime stabling with selected services terminate at Gordon/North Sydney.
During the PM peak, half of all citybound services (ones that are the "regular" half hourly service) continue to Lindfield and the supplementary service (which follow the regular service) continue to Gordon, returning to the Western Line on the subsequent trip.
