Leading the liturgy were two wardens from the Anglican community, Mrs Pauline McCulloch and Mrs Jean Potter, with Fr Max Davis representing the Catholic community.
Greeting those present, Fr Davis said the uncertainty of life was never more prevalent than it was for railway workers.
"This is a time when we can reflect their goodness and love. Their families miss them, love them, and think about them," he said.
"We can share our own life stories along with the hope of our Christian life."
Monument chairman, Chris Holley, said it was important to have the Australian Railway Monument rededicated each year.
"It is only right that we should remember deceased rail workers, especially those who gained their livelihood from the railways."
"Such a rededication service is a must, particularly as the national Australian Railway Monument is located in the railway town of Werris Creek", he said.
Those present moved from the amphitheatre are the NSW memorial wall, where Fr Max blessed the monument in memory of those whose lives have been lost while working on the railways.
The Australian Railway Monument is a memorial to all railway workers from throughout Australia, who lost their lives because of an accident on the job.
It is estimated that almost 10,000 rail workers were killed throughout Australia on the railways over the last 155 years.
The nationally acclaimed, multi award-winning Australian Railway Monument and nearby Rail Journeys Museum at the Werris Creek Railway Station, are open seven days a week 10.00am to 4.00pm.
