Rail upgrade
A $6.5 million upgrade of the Newcastle and Central Coast line occurred last weekend with buses replacing trains between Woy Woy and Hornsby.
A cityrail spokesperson said the upgrades were undertaken to maintain the safety of the rail network and to improve the efficiency and reliability of cityrail's train services.
Some of the upgrade work included rail resurfacing, bridge refurbishment, track reconditioning, ballast cleaning, signal upgrading, rerailing, overhead wiring renewal, corridor cleaning and vegetation management.
Trains were back to normal on Monday, October 25.
