Dart and Luas lines
Homes on the Dart and Luas lines now cost one third more than the Dublin average - and their prices are also going up faster than the rest.
That's according to property website Daft.ie, which has published new figures today for the first quarter of the year.
The average asking price in Dublin is €383,000.
However, that rises to €512,000 - a 34% premium - for properties closer to main transport stops.
Commuters along the Dublin south coastline pay most, with prices averaging €670,000.
Houses near Sandymount (€870,000) and Dalkey (€848,000) DART stations are the most expensive.
Along the Luas lines, the highest average asking price of €788,000 is for homes close to the Beechwood stop.
Homes near Spencer Dock are the most expensive on the red line at €724,000.
The latest Daft.ie report also looks at house prices along the proposed route for the planned MetroLink.
Currently, the most expensive homes along that route are closest to Charlemont (€724,000) and Tara Street (€573,000).
