In the beginning, trams ran on rails across Dublin city.
And buses started travelling on roads throughout the city.
And a DART appeared and ran north-south along existing rail lines.
And then Luas began running to the south and west on different tracks.
And next came (quality) bus corridors but few new buses or park-and-ride.
And, as road traffic continued to grow, congestion increased and commute times lengthened.
And then came plans for more Luas, a Metro, an underground rail link and more bus corridors.
And chaos reigned supreme as no one took charge and the buses, Luas, Metro and rail all went their merry ways.
