I've just completed a short scenario where you take the class 166 from the depo yard to the station so it can proceed with the daily runs. I wanted to ride along but whats intresting to note is that you can't hear the engine sounds on it while it's controlled by AI. It even goes up to 100 kmph in under 30 seconds with the engine on what it appears to be turned off or idle. Never stops at any station that's suppose to. At the momment im on the 166 and its like a runaway train, just travels at high speed, no engine sounds and ignores the stopping points. Currently reporting on GWR route 3P51 Reading Traincare Depot to Reading.
