COMMUTERS on the Newcastle and Central Coast line will take part in a three-month trial of quiet carriages on CityRail trains.
The trial starts on February 13.
"Customers are telling us they want a noise-free environment on their train trip," Transport Minister Gladys Berejiklian said.
The first and last carriages of all six- and eight-carriage trains and the last carriage of four-carriage trains on the line will be designated 'quiet carriages'.
"Those who wish to use the designated quiet carriages will be asked to refrain from loud talking, playing loud music and using mobile phones."
