Also ironically the name of the urban transport light rail system in Dublin.
Ironic? You don't think it might have been a deliberate choice for a transport system in Ireland?
Using speed in the context of anything to do with CIE is always worth a chuckle.
That's not a problem then - CIE has absolutely no role in the ownership or running of the Luas. Ask anyone who used to sit on a 48A during rush hour (or even just stand waiting for one to turn up) whether they think the "Speed" name is justified.
Ah the Gerry Lee, a boon to Dubliners.
