The specially ordered train, which is curated by the Little Museum of Dublin, is adorned with graphics and text meant to pique the interest of all DART riders.
Since its first trip on July 23, 1984, the Dublin Area Rapid Transit has transported about 670 million people to their destinations.
Every year, DART trains travel more than 2.44 million kilometres, or more than three moon journeys round way.
With a total of 31 stations served, the DART was expanded in 2000 to include Greystones and Malahide. In the years that followed, further stations at Grand Canal Dock (2001) and Clongriffin (2010) opened.
In 2025, a 32nd station will open at Woodbrook, halfway between Bray and Shankill.
When DART was initially presented, according to Minister of Transport Eamon Ryan, it was dubbed a 'Rolls Royce' answer to Dublin's transport issues and was 'far beyond the spec we needed for the city'.

"It’s just as well Iarnród Éireann and all those involved in developing DART didn’t listen to the naysayers back then," he said.
"Dublin residents have grown up with the DART for generations. It has served as the setting for several well-known books, films, music videos, and accounts of Dublin culture and its residents, both real and imagined."
In the last forty years, Dublin life has been inextricably linked with the DART.
