Hi there! Sydney to Gosford on the NSW east coast is a beautiful route combining suburban all-stop services with express services. Some classic Australian bushland and waterways can be seen along the northern half - including tunnels, bridges and trackside waterways.

Any Sydney City rail route would be perfect. I would love to drive a Tangara or a K and C set. The Bondi to Cronulla route was created for BVE over 10 years ago.
