Class 484 Horn Incorrect

After being on the class 484 today and after listening to the actual horn I can see the horn used in tsw 3 is incorrect surely it’s easy to obtain the horn sound ? So why didn’t they use the actual horn sound ?

 

Do they use the horn in real life or the whistle?

 

As far as I know, they use the horn

 

In my opinion the horn sounds fine, maybe the pitch is off slightly but it's not terrible.

 

I can 100% tell you it’s incorrect It’s definitely a reused or an substitute horn it’s close don’t get me wrong just bugs me alittle but I love the class 484 in tsw 3 t it’s lwell done

 

True just disappointed as all the other sounds are spot on
