Slightly off topic.Imagine if Guinness had reinstated some of their system. Tourist would love a trip in a Guinness train along the cobbles before they do an internal tour. I remember when I was young (very young) marvelling at the speed of the trains on the curves! The trains were always immaculate and looked a million miles away from the Bord na Mona stock.
Transport has come a long way from CIE horse drawn carts and Guinness trains, but the memories are still vivid and happy.
