Dr McDonald said it's important the locals living alongside the freight line, who already have to contend with noise from commuter trains, receive noise barriers.

``My argument will be that the State Government should pay for half of the cost of the barriers and that is the argument I've been putting to the Premier and the Transport Minister,'' he said.

His motion is made up of three points, which call on his government colleagues to: ``note the concerns of the residents of Casula about the adverse health affects of rail noise on their lives''.

``Note that these noise affects will increase with the construction and utilisation of the Southern Sydney Freight line by the Australian Rail Track Corporation,'' the motion says.

``Call on all levels of government to work to find a solution that results in effective noise barriers for all of the residents of Casula.''

The motion was placed on the Legislative Assembly list of motions on Wednesday, October 21, but has not yet been discussed in Parliament.

Dr McDonald said that the motion was inspired by the Greens intention to move a bill in the Legislative Council, calling on the State Government to take full financial responsibility for the noise barriers.

``When they suggested moving a bill, I thought that there was no real chance that that could be passed,'' he said.

``But a motion is a great idea, because it makes more members aware of the issue and gets everyone talking about it.

``I think it's important that the motion includes a commitment for all levels of government to work together on this issue, because that's the only way it can be solved.''

Liverpool MP Paul Lynch said that he has met with several of his constituents about the noise barrier issue on many occasions.
