6,000 people have signed a petition, calling for reduced train fares for Newbridge commuters.
The town's train station is just outside the Short Hop Zone.
A one-way ticket to Dublin from nearby Naas/Sallins, using a Leap Card, is €3.75.
From Newbridge, the same journey costs €15.
Ciara O'Reilly is a Labour representative in Newbridge.
She says stations elsewhere, a similar distance from the city centre, have been included in the Short Hope Zone.
