The Red Line is one of the two lines of Dublin's Luas light rail system. The Red Line runs in an east–west direction through the city centre, north of the River Liffey, before travelling southwest to Tallaght, with a fork to Citywest and Saggart. The Red Line opened on 26 September 2004.

Busáras is the central bus station in Dublin, Ireland for Intercity and regional bus services operated by Bus Éireann. Designed in the International Modern style, Busáras is also a stop on the Red Line of the Luas system, in Store Street just before the terminus at Dublin Connolly railway station. Áras Mhic Dhiarmada is the official name of the building, which also includes the headquarters of the Department of Social Protection. CIÉ, parent of Bus Éireann, leases the lower floors from the department. Áras Mhic Dhiarmada is named after Seán Mac Diarmada, a leader of the Easter Rising in 1916.
