HUNTER trains are offline for an overhaul during the long weekend, with trackwork on both the Newcastle and Hunter lines.
Buses are replaced all services between the Hunter and Sydney until Tuesday.
The trackwork coincides with Stewart Avenue closing for light rail construction and a major program of Australian Rail Track Corporation upgrades.
The ARTC has more than 1200 staff in action until Tuesday working to resurface tracks and tamping, repair bridges, conduct signal works and other tasks.
“We align these works with other rail maintenance scheduled across NSW to minimise overall impacts on rail customers – and the ability to deliver these when there are fewer trains running means we can get the most amount of work done, as safely and efficiently as possible,” group executive Hunter Valley Wayne Johnson said.
“Trucks and heavy machinery will be in use, as well as entering and exiting work sites. We ask the community to please take caution around the rail corridor during this time and be aware there may be some road closures or detours in your region.”
It follows a shut-down in April for upgrade works.
