...expert mode, light loco, pressure 200 of 225, no change to the reverser (25) and going downhill at about 80mph. Was trying to hit top speed (90) but only reached 84.3. It's my first week on TS - I've read some of the many guides and think I have basic understanding.
Sometimes, if the reverser has slipped, the speed will go to the maximum it can on that particular setting
25% reverser seems high for that speed. Granted she's LNER but there's a notice next to the reverser in V2 Green Arrow telling drivers to have 25% or less at any speed over 25mph. Having the cut-off too high for a given speed will slow a kettle down- I take it because used steam takes a certain amount of time to clear, the more steam the longer that takes and it can work against the power stroke if the cycle is going too quickly. Caveat: that could be completely muddled or just plain wrong but I'm sure someone get this straight.
