Db 204 Sound Bug?

So I wanted to test something in the training center with the old DB BR204 and have de-equipped the complete locomotive for this and I noticed that there is a constant knocking sound whether I don't run or the locomotive is in operation

 

That is normal, that's what you hear when the engine is cooling down. I am pretty sure more trains in TSW makes that sounds (and also in real life

 

Lel ok I never hear it before in tsw

 

Like your car's exhaust crackles after a long tour.

 

Ok, wow, I learned something new again, thank you ^^

 

What about the loco not showing in service mode or scenarios?

 

The locomotive belongs to the main Spessart railway and must be purchased separately
