2023 - Update 5:
It's hard to think of a route that gets such consistent variety as the 41s. The Navan Road group such as the 38s or 39s also come to mind, but much of their variety is peak-hour half-lap fillers operated by Harristown, blink and they're gone. But the 41 group always has variety, seven days a week. Summerhill allocate all of their vehicle types, with a mix AXs, EVs, GTs, PAs and SGs being the norm. There are also a number of Harristown operated departures Monday to Friday that aren't just peak hour but operate across the day, which brings a mix of AXs, EVs (including former Ringsend 1-7) and VGs. I spent the morning of the 4th February around Swords catching much of the variety of buses in the town, which is not limited to just the 41.
