The BR Class 66 on ECW is missing engine sound on the first two levels of the throttle. The engine gets silent until you go on level 3 or back to idle. I have the impression a similar issue occurs on the BabyBullet on throttle level 6 - I mean, this level is at least significantly quieter than level 5 or 7. Can someone confirm that? The issue is not present on the BR Class 66 on the GWE route!
