A trip on the train is the best way to see all of the Lower Gardens. Over 4.5km of narrow gauge track, weaves its way through the trees, revealing many pleasing vistas. The railway takes you around the lake and grounds passing the Castle Folly, the Tree Circle with the “Orb” and the newly installed “Long Sleeper” sculpture on the Spiral Mound before returning to the Station. The ‘Duchess of Difflin’ steam engine, with her carriages in the traditional red and cream livery of the “Wee Donegal” and the ‘Earl of Oakfield’ blue diesel engine give pleasure to children and enthusiast alike. During July and August train trips are available at regular intervals during opening hours and offer an excellent opportunity to view the lower gardens in comfort. In the months of April, May, June and September the train runs at 3pm on weekdays. Tickets and departure times available from the station. No booking required except for group visits. The trip will take about 15 minutes.
