Almost 1000 signatures have already been put to paper after just one week of the campaign to bring disabled access to Wentworthville Station.

Yookie Mjoberg, who signed the petition on Tuesday morning, said she had been asking for lifts since she moved to Wentworthville more than two decades ago.

"I'm 75 and honestly it's horrible," she said.

"I live by myself and I have this wheelie bag and I can't get up the stairs with it, everyone needs to carry groceries.

"I see other old women and they struggle and younger women with prams.

"I've asked so many times at the station and they say they keep trying. We need to get [lifts] in tomorrow."

Shirley Silk from the Wentworthville Business committee, who organised the petition, was spurred into action after she heard a large business had refused to set up in her suburb when they discovered the station had no wheelchair access.

"Our mission is to get 10,000 signatures," she said.

Parramatta MP Geoff Lee said he would take the 10,000 signatures to the NSW parliament.

"I'm delighted to give my full support to the Wenty Business Committee," he said.

"Within a week over 50 businesses have joined the campaign, collecting more than 920 signatures.

"We're on our way to the targeted 10,000 signatures."
