PASSENGER trains between Sydney and the Hunter have resumed after a break-down at Cowan severed the line.
Hamilton-bound trains were unable to pass the area on their journey north, forced to halt at platforms while repairs were conducted.
Commuters are still urged to allow plenty of extra travel time and check indicator boards as the rail network attempts to catch up.
Train stopping patterns may change due to the closure.
The freight train break-down is the latest delay of the shared passenger and freight lines running through the region.
The Newcastle Herald reported in April that there had been more than 400 incidents where freight trains delayed or hampered passenger trains since last July.
That figure equated to 1.6 delays each day over the 244 days between July 2015 and April this year, and excludes the Hunter line between Maitland and Newcastle.
In April a burning freight train near Cardiff station forced more than 90 passengers to evacuate the vehicle and an oncoming passenger train.
Buses subsequently replaced trains for roughly 10 hours.
