2023 - Update 17:
A nice surprise recently was the return of AH1 from its repainting cycle. With Dublin Bus operating a 4-year cycle for buses to be repainted buses of 2019 vintage are due this year. A turn up for the books is that it didn't come back in the standard TFI livery as might have been expected. What's rare is wonderful, so the fact that the hybrids are staying in their previous livery is great news. In the meantime VH1 is also back in its former livery. This repainting cycle has meant that hybrids have been harder to catch recently, so it was a nice surprise to find it on Route 151.
