The 29A, which can trace its origins back to the GNR(I), is operated from Clontarf Garage. The first time I travelled on the route was on the 14th November 2012, just prior to Network Direct brought about some changes. On the day I travelled on AV 235 out to Newgrove, only to discover there is really no such place. It would be more accurate to say it terminates in Donaghmede, but the last stop was at an area called Newgrove Cross, which became Newgrove in the Dublin Bus lexicon. The highlight of the 29A routing is the detour it takes in Raheny around All Saints Park. The other routes on the Howth Road stick to the Howth Road.
On the 16th October 2014, I revisited the 29A to witness a few changes. In November 2012 the route had been extended along the Grange Road to Baldoyle. It was also given a clockface, twenty minute timetable, and was allocated GTs from Clontarf Garage. However the day before I revisited the route, the newer SG class was introduced on it. These buses from the rear evoke the old D-Class that operated in Dublin. It is worth noting that up to 2011 RVs were common on the 29A but in 2014 the newest buses were now allocated. The 29A routing as far as Newgrove is the same as prior to Network Direct, reaching Donaghmede via Raheny, Killester and Fairview. At Newgrove Cross it takes a right turn along Grange Road and reaches Baldoyle at the Coast Road via Willie Nolan Road. One notable feature of the route is that parallels, and crosses, the main Dublin - Belfast Railway line and provides a useful relief to the DART service when it is suspended for engineering work.
