The NSW Premier announced a $4million commitment to upgrade the car park last Friday, June 13.

``We want to encourage local commuters to use public transport and improved park and ride facilities will achieve that,'' he said.

``Local working families are suffering under the rising cost of petrol. I know that and I want to help them get out of their cars and on to trains.''

Wattle Grove resident Roy Carter said Holsworthy station needs at least 1000 more parking spaces due to the high demand that it has experienced in recent years.

``Holsworthy has turned into a city-type station. People from Sandy Point, Chipping Norton, Wattle Grove, Glenfield and even Hoxton Park prefer to travel from Holsworthy,'' he said.

``Liverpool is seen as dangerous and scary place with alcoholics and drug addicts hanging around. There aren't any pubs or even shops near Holsworthy station. It's quiet and safe and it's the only place I would allow my children to catch the train from.''

Mr Carter said the demand on the station will grow even further if a proposed freight terminal is constructed on former and current Defence land at Moorebank.

``If the freight terminal is put in, huge semi-trailers will block up all of the traffic on the M5 and M7 and create gridlock for locals trying to get to work each morning.

``So the Iemma Government is trying to soften the blow by upgrading this car park. Only they haven't gone far enough.''

Wattle Grove resident Andrew Kingston said: ``This is another example of the State Government trying to placate locals with promises of infrastructure that was already needed.

``There haven't been any guarantees that City Rail will put on extra carriages and services to cope with the 350 extra people using the service.''

Menai MP Alison Megarrity said a community consultation process would be undertaken.
