Many bus services across Dublin will see an increase in service from this weekend.
Nine more Dublin Bus routes will be operated by Go-Ahead from Sunday.
Routes 17, 104, 114, 161, 220, 236, 238, 239, and 270 will have timetable enhancements and increased weekend services on some routes.
It's the latest phase of changes being introduced on about 50 bus routes in the city, operated under the Transport for Ireland brand, by both Dublin Bus and Go-Ahead Ireland.
Head of public affairs with the National Transport Authority Dermot O'Gara said passengers will see improvements in frequency and service levels.
He said most passengers "won't really see a difference", admitting that timetables will be "broadly the same" with the same fares.
However, he promised that there would be some earlier and later departures, extending the timetable both in the morning and evening.
The changes coincide with an increase on Dublin Bus services on routes 26, 66, 66A, 66B, 66X and new route 66E.
Route 26 will be extended to operate between Merrion Square and Liffey Valley. New route 66E will be a Monday to Friday service between Maynooth and the city serving Leixlip, Lucan and Chapelizod.
