Two (IÉ 6203 and 6205 - I think the BR numbers were 99524 and 99526) went to the Killashee House Hotel (now apparently just the Killashee Hotel) in County Kildare. The hotel seemingly intended turning them (and, I believe, an IÉ Cravens coach) into a restaurant, but this didn't happen. 6203 went on to a tree nursery in another part of Kildare, where it originally served as a coffee shop (photo at

The other coach (6205) was derelict by 2013 (photo at
