Howth Junction is a double junction (two running lines) where the Howth Branch diverges from the Dublin-Belfast main line.
Both routes are electrified for DART (Dublin Area Rapid Transit) services.
I made these views digitally using my FujiFilm X-T1 on a visit with Jay Monaghan last week.
In addition to DART electric trains, I made photos of Irish Rail diesel suburban services, the Dublin-Belfast Enterpriselong distance train, and a laden Tara Mines zinc freight.
Some autumn foliage near the junction made the location more colourful.
