Playing Peak Forest with the 4F for the first time and then the button for the whistle and I don't know why but it bugged me that the whistle was horizontal instead of vertical but I don't know why it's so little but bugging. With the consoles especially the Xbox One the cuffing when you reach the late teens and earlier 20s (mph) it gets inconsistent and if you want to run the 8F and 4F on WSR the chuff is fixed at 26 mph and if you want to do it properly you hav to speed Improved Whistles with deeper Stanier Hooters but also keep the 'kettle' as I call it but I do love the whistle in the game already this is an improvement
