Hornsby is located on the T1 (T1), one of Sydney's operational metro corridors. It sits between Asquith and Wahroonga, making it a convenient stop for the surrounding area.

What makes Hornsby particularly useful is its interchange connection with T9. If you need to switch between lines, this is where you'll do it – and you won't need to exit or purchase a new ticket. The interchange corridor is clearly signposted with color-coded directions.
