Just pulling your leg about the Sunnyside Fritz
Actually the D&S is a passenger carrier so it's a little unreasonable to expect them to maintain a fleet of old wooden Freightcars just for the occasional photographer special. That's where the likes of the DRHS and the neighbouring C&TS fit in the picture. I did however get suckered into purchasing a flight to the USA back in 1994 for a "Freight" special, a freight that consisted of two(?) yellow boxcars, a 6500 flat and two EBT coalhoppers with caboose. Looked more like a nondescript m-o-w worktrain, that quite frankly was not worth the effort and expense to get there. I'd had my fill of worktrains of all types on the NZR.
