Wagons from a coal train have derailed (these have largely remained upright) and another coal train running in the opposing direction has struck these resulting in damage to the locomotive.

“Some wagons are on their side,” an ARTC spokesman said.

“There have been no injuries reported.

“Train services are currently suspended between Muswellbrook and Singleton (between Newdell rail junction and Drayton rail junction).”

Track damage has occurred, and repairs will be required, but the extent of these will be subject to further investigation as well as recovery and removal of the wagons and locomotives.

The incident has been reported to independent transport safety investigators and the site is currently quarantined.

There is no forecast currently available for a return to operations, however further updates will be provided as more information comes to hand.

Passengers on those trains, which are stopped at Singleton and Muswellbrook, are expected to be bused between the two stations and placed on the opposite train to continue to their destinations. 

Transport for NSW is advising passengers to allow extra travel time, listen to announcements and check indicator boards for travel on the Hunter line. 

Buses will replace trains between Singleton and Scone. 

Extensive delays are expected.
