Hi, Driving the class 31 on GWE (legends) from Reading to Paddington and noticed the engine sounds cut out when power notches 3 and 4 are selected whilst on the mainline. Sounds are audible in notches 1, 2, and 5, and when going back down from 3 into 2. Here's a short video: Here's another video from the same route and session in the depot. Sounds are working fine here (ignore the speed lol): Thanks!
