Interesting!
I hadn't thought of it as crude, and it isn't compared to most other Roundhouse and Accucraft models, but the Accu Countess shows it up on the detail front and valve gear appearance for sure. For half the price too, but doesn't have the springing, whistle or a water gauge that actually shows the real level.....&: hmm, it's still awful expensive though!
I bought mine with money I had been left, and to be honest if it wasn't for the memory it represents, I probably would have sold it by now.
Bob, it's not a pressure thing - same stroke cylinders, bigger wheels - it's all about the relationship of them applying torque to the periphery of the wheel I think. She just takes off too quickly from stationary regardless of how careful you are, or pressure on the clock. I chatted to Roundhouse about it when I first got her, and they agreed! The smaller wheeled locos will always be easier to control. A huge load helps though, which is why she is normally seen on big trains on the L&L.
