Dublin Bus, which serves Leixlip, Celbridge, Maynooth and Ballymore Eustance is moving back to a Monday to Friday timetable, from today.
It has been operating a Weekend Plus style schedule.
Dublin Bus is asking people to avoid peak hours while school children and essential workers are commuting.
"We ask customers to avoid travelling at peak times when school children and essential workers are using public transport and to only use public transport for necessary journeys. We advise customers to plan their journey in advance and allow additional time. We will continue to monitor services and capacity will be added where possible. "
