Very specific question, but I'd like to know. When I say 'fixed', I mean as far as the sounds go. I recall hearing a lot of negative feedback about how the sounds were used on the 150 in West Cornwall Local. It put me off buying the route, since I would rather wait until it is fixed. No point having AP sounds if they aren't done right.
Its not a sound issue. It's a "how the engine, gearbox and mechanicals work" issue, which trigger the sounds. And no, Rivet haven't said they're working on it
