MetroLink, the new metro service planned for the city and outskirts of Dublin, will operate primarily as an over ground service but, as it will venture underground as it approaches the airport, is set to become the first underground travel service available in Ireland, should it get the go ahead from planning and transport authorities.
Though most people have welcomed the news, it has caused some controversy in areas of Dublin where the works to build it will have a major impact on the communities.
Renowned GAA club Na Fianna, for example, fears its grounds will be negatively affected – this has lead to some protests there – but it remains to be seen whether or not it will get the green light.
The first underground rail system in the world was the Metropolitan Railway, which developed into what is now known as the London Underground. It opened in 1863 – 155 years ago!
