Here’s a suggestion. Maybe can you please port over the BR442 sounds from either Köln-Aachen, Dresden-Riesa or Kassel-Würzburg? Because the current sounds for the BR1442 in-game I think were either synthesised (instead of recorded from the real thing) or mixed very badly. In real life, the sounds of a BR1442 sound like a BR442. So maybe please can you port the sounds?
They did port the sounds to the BR 1442 but it completely broke the train. If they are gonna add the newer sounds, they'll have to rebuild the train from scratch.
Why not use the Br442 from Dresden Riesa and Repraint the outside of the train? (Even though the inside livery won't be the same)
