Sydney Trains is getting a new network map to coincide with the opening of Sydney Metro Northwest on May 5. This map includes the new Metro line in its signature aqua blue running from Chatswood to Tallawong. A new T9 designation has been introduced for Northern Line Hornsby to Gordon via Strathfield services, in the red colour that the line used under the old CityRail branding.
We are yet to receive a full copy of the new map but it is our understanding that the map will remain the same outside the area of change seen in the image above.
