Berejiklian said the ROC will deliver significant benefits to customers, including faster communication and much better co-ordination during incidents, which will ultimately help reduce delays and improve punctuality.
"Labor left our railways in a terrible state of disrepair after so many years of mismanagement, and on top of our improvements to date this world class facility will provide the public transport services customers deserve," Berejiklian said.
"Improved technology and updated communication systems in the ROC will mean customers will have access to far more accurate, timely, relevant and consistent information, and delays will be reduced as a result."
The NSW government will initially invest $11.4 million in 2014-15 for the project which is expected to open in around 2017.
Sydney Trains chief executive Howard Collins said the new centre will bring together the functions currently performed at a number of different sites across Sydney.
Out with the old technology
"The performance of trains are impacted by outdated technology and the fact that so many control functions are spread across multiple locations," Collins said.
"At the moment communication between the train network control centre, frontline staff and customers has to go through a number of channels, and the new ROC will help to modernise the network to ensure we improve the daily journeys of our customers.
"Improving communication means our customers will get information faster, and will lead to faster more seamless operations, supporting our goal to deliver more services and reduce customer delays."
Collins said there are currently 2,800 passenger train movements on Sydney Trains network each day, as well as 300 freight services, with around one million passenger journeys every weekday.
