In September 2011, Dublin Bus received a significant technological upgrade with its introduction of real time passenger information.

Express buses (branded "Xpresso") operate on similar routes but have a limited number of stops and a higher minimum fare.

[8] The tour usually runs in the evening time and includes two stops where passengers leave the bus behind and visit locations where ghosts have allegedly been seen.

[20] The 99 is the first Dublin Bus route to serve Chesterfield Avenue and important Phoenix Park sites such as Áras an Uachtaráin.

On 6 December 1991 Dublin Bus launched its first 'Nitelink' service aimed at facilitating Christmas revellers returning home from the city centre.

[22] The trial service operated from 6 December 1991 to 4 January 1992 (except for certain holidays) on a Mon-Sun basis and cost a flat fare of £2 per person irrespective of how long or short their journey.

[22] Nitelink is an express service, meaning passengers may only board the buses at the city centre termini and other select locations along the way, although they may disembark at any normal bus stop along the route.

Dublin City Councillor Colm O'Rourke criticised the move, noting "The Nitelink is not just for clubbers; it's for workers and anyone else who needs a low-cost service to get home safely – including people on low wages or perhaps students who work the weekend".

[52] At midnight on 1 December 2019, routes 15 and 41 began operating on a 24-hours-a-day, seven-days-a-week basis with no difference in fare, marking the first time Dublin had a regular night bus service.

For instance, the success in attracting to the city, major employers who are headquartered many time-zones away, serving markets around the world, means that commercial and economic activity in Dublin continues around the clock".

[53] In June 2022, chief executive of Dublin Bus Ray Coyne told 'Breakfast Business' on Newstalk radio that of the six 24-hour services the company was currently running, route number 15 was "probably the most successful one".

[54] Commenting on the 24-hour services in Sep 2022, Gary Kelly, Chief Inspector with Dublin Bus explained how they were a "huge success" witnessing a "a big demand".

[26][56] On 28 November 2021 the National Transport Authority implemented Phase 2 of the rollout of its latest Dublin network with the C Spine, that consists of new C1-C4 routes serving the west of the city.

Upon the introduction of the C Spine, Minister for Transport Eamon Ryan said that it "provides the communities on its route not just increased frequency, but also a night service offering commuters 24-hour bus connections.

Anne Graham, CEO of the NTA, stated that "Today's launch is one further step in the delivery of an effective and efficient bus service for the Dublin city region.

[54] Speaking to TheJournal.ie in August 2022, a spokesperson for the Department of Transport noted that 24-hour services on the planned E-Spine, F-Spine and O-orbital routes set to start in 2023 are under consideration.

[66] In addition, they noted that "the NTA has indicated that there is potential for each of the spine groups to have at least one route running 24 hours, but final decisions will be made closer to the time of each rollout".

[tone] The company noted the challenges facing commuters in post-COVID Dublin, but also the opportunities: "Thousands of taxis have left the market.

[50] In late September 2022, Transport for Ireland launched a campaign named "Around the city, around the clock" aimed at highlighting night-time bus services in Dublin in the run up to Christmas.

[68] The company drew similarities between their proposed Dublin transport plan to that in place in Copenhagen, a city of comparable size and shape.

[69] As part of their contract, Jarrett Walker + Associates were not tasked with the expansion of 24-hour and night-time bus services in Dublin, as this was a separate decision taken by the NTA without their involvement.

[58] The N4 travels from Point Village to Blanchardstown Shopping Centre serving Killester, Whitehall, DCU, Finglas and Connolly Hospital.

Dublin Bus cites high licensing fees from fellow state-owned company, Ordnance Survey Ireland (OSI).

Paying the normal fare using a TFI Leap Card allows free transfers to other Dublin Bus, Luas, and certain Iarnród Éireann services for a 90-minute period.

[92][93] In general, Dublin Bus encourages prepaid or reloadable ticket use, and for cash payment it operates an 'exact fare' policy.

Many ex-CIÉ and Dublin Bus types have been acquired by private preservationists, some of whom associated with the Transport Enthusiasts Club (TEC).

The vehicles are garaged, restored and run by the owners without state funds and take part in films, television programs and in vintage rallies.In 1989, a youth grabbed the steering wheel of a Tallaght bound double decker as it turned the corner opposite Christchurch and the bus crashed onto its side.

[96] On 21 February 2004, at Wellington Quay, Dublin, a bus mounted on pavement and crashed into a queue of 30 people, killing five and injuring 14.

[97] On 5 February 2009, a bus en route from Abbey Street to Artane collided with a tree on North Strand Road and the entire roof section was torn off.

[99][100][101][102][103] On 16 March 2019, an out of service double-decker bus (VG1) collided with a tram at the junction at Queen Street near the Smithfield Luas stop.
