Dublin Luas tram 3016 climbs up the steep Stevens Lane on 23 May 2018 with a service for Tamhlacht (Tallaght). It has just left the stop opposite Dublin Heuston station (at the bottom of the hill), and will shortly be turning right into St. James's Street. The tram system uses the international standard gauge of 4 ft 8½ in, rather than the Irish standard gauge of 5 ft 3 in.
