A charity is hoping to donate over 25,000 shoe boxes, filled with Christmas presents, to homeless children.
It's part of the 'Fill a Luas' campaign, now in its fourth year, with the Inner City Help Homeless (ICHH) charity.
Since the event began, there's been a 400% increase in the number of homeless children in Ireland.
ICHH CEO Anthony Flynn said: "This year's event is a bit special, with a focus on families in emergency accommodation with the addition of Santa's Grotto.

"Today is a day where the public, our volunteers and our charity partners come together with the people we support on a daily basis to bring a smile to people's faces.
"We want today to be a special day for the most vulnerable in society where they can come to Connolly for food and a haircut and to be treated for a change with Christmas around the corner."

Volunteers will be on site at Dublin's Connolly Station until 7.00pm tonight.
They're also offering breakfast, lunch and dinner for the homeless - along with free haircuts, Santa's grotto, Giggles the clown, buskers, snacks and other surprises.

People can also drop shoe boxes to the Luas depots in Red Cow and Broombridge until 5.00pm.
They're hoping to beat the previous record of 26,000 boxes.
