Hi Mike,
I did not get many photos on this occasion but the place is very interesting, historical and beautiful. The railway following the course of the Avoca River all the way down to Arklow. Copper was mined here in the past and transported to Arklow, Wicklow and Dun Laoghaire by rail. Before the arrival of the Dublin, Wicklow and Wexford railway, a tram-line type system existed for transporting the ore to Arklow Port. You may find the attached link of interest.
