Know what you mean about 63 - still lots of stuff like Derry Road and Mallow-Waterford, Burma Road etc…but if you were to offer me a week in history to go exploring around, I’d pick 1950 - lots of mileage but also lots of variety, both steam and I/c, not to mention 3’ gauge. Mind you, 1910 also has its attractions - imagine the rainbow parade of trains through Ballysodare……
