Dublin United Transport Company (DUTC) and was very advanced for its day, with near-full electrification from 1901. From the 1920s onwards, the DUTC began to acquire private bus operators and gradually closed some of its lines. Further declines in passenger numbers were driven in part by a belief at the time that trams were outdated and archaic. All tram lines terminated in 1949, except for the tram to

In November 2005, the government announced a €34 billion initiative called
Transport 21 which included a substantial expansion to Dublin's transport network. The project was cancelled in May 2011 in the aftermath of the
2008 recession. Consequently, by 2017 Hugh Creegan, deputy chief of the NTA, stated that there had been a "''chronic underinvestment in public transport for more than a decade''". By 2019, Dublin was reportedly the 17th most congested city in the world, and had the 5th highest average commute time in the European Union. The Luas and rail network regularly experience significant overcrowding and delays during peak hours, and in 2019 Iarnród Éireann was widely ridiculed for asking commuters to "''stagger morning journeys''" to alleviate the problem.
