T1 Line The T1 line also known as North Shore & Western Line is a commuter rail line operated by Sydney Trains in Sydney, New South Wales, Australia. It serves the North Shore, parts of the Inner West and Western Suburbs. This line had an annual ridership of 142,853,000 in the 2017-18 year. This line also goes over the Sydney harbour bridge. T9 Line The T9 line also known as the Northern Line is a commuter rail line operated by Sydney Trains in Sydney, New South Wales, Australia. It serves some of Sydney's Inner West and Northern suburbs. It was spun off from the old T1 North Shore, Northern & Western Line as a separate line in April 2019, to distinguish and make it more easily identified from the other T1 services. It is also a reincarnation of the older Northern Line which was under operation until 2013.

The depot features nine roads under the main shed (numbered 1-9), five outdoor roads (numbered 11-15), two of which (11 and 12) are elevated, a train washing facility (16 road) and several short outdoor storage sidings. The depot is responsible for the stabling and maintenance of all trains on the Northern, North Shore, and Western lines. Some Sydney Trains T sets are maintained at Hornsby. Some H sets (Oscar), are stabled and maintained at Hornsby. The A sets (Waratah), are stabled at Hornsby but the maintenance is done at Auburn Maintenance Centre
This brings back the memories of 2012 (my last trip to Sydney)... Personally, if DTG were able to do this. add the ECRL (Epping Chatswood Rail Link) to complete the Northern Line which sets the era around 2015 pre-Metro. Not mention, there are Intercity V sets, C and K sets which can be included. This would total 58.7km from Hornsby to Epping via Redfern. T9 prior to the merge with T1.
