The National Transport Authority has said there are "no plans" to extend the new TFI 90 minute rail fares to Skerries and Balbriggan.
The new fare allows commuters across Dublin to travel and to change between public transport services for a €2 Leap Card fare within a 90-minute window.
The boundary for this fare on rail and DART services covers Zones 1-4 and extends as far as Rush and Lusk on the northside and Bray on the southside, being of "comparable distance from the city centre, approximately 23 track km’s".
