According to Iarnród Éireann the work is part of a n33m spend on providing greater accessibility for people with mobility and sensory impairments at stations across Ireland.
The 2010 programme provides for lifts and a footbridge at the Sallins sta
tion.
A spokeswoman told the Leinster Leader that planning meetings have taken place with Kildare County Council and it's hoped that construction will start "by late 2010".
This follows criticism by Cllr. Paddy McNamara about facilities at the station, including a promised upgrade, to include a waiting room, toilets and coffee shop, which was granted planning permission in two years ago.
Cllr. McNamara, a founding member of the Naas and Sallins Rail Users Group, was especially critical of the absence of a lift to allow disabled travellers cross from one platform to the other.
He also complained about this to the Ombudsman, who decided the company should be given more time.
He noted Irish Rail had said this would be done in 2009 but little has happened since.
"In fact progress seems to be going backwards," he claimed.
He added: "What is most galling for those waiting for these facilities is that millions have been spent on the construction of a brand new station at Kishogue, between Clondalkin and Adamstown.
It appears this station is surplus to requirements and will not be opened in the foreseeable future, if at all. This money could have been spent in Sallins and represents a shocking waste of scarce resources. Surely heads should roll at Irish Rail."
