Xbox Series S Br146 Dresden-leipzig And Frankfurt-fulda With Rh1116 Horn

The br146 from Dresden-Leipzig route has the same horn sound as the Rh1116/br182. I've already noticed this on the Frankfurt-Fulda route, but I didn't pay much attention to it because I used the br146s on other routes with the correct sounds (I can't do this now on Dresden-Leipzig because I wouldn't be able to use the announcements on board the train).
