From last night's stream: In TSW3 of course... BR Class 66 has new sounds from Armstrong Powerhouse The BR class 375 will have the soundset from the BML 377 I've seen these questions floating around, so it's confirmed that the TSW3 DLC will have new sounds (where required) compared to the TSW2 versions
Good news for the 375, There was also a mention of 395 sound improvements in the article, I’m interested to see what’s happening there. I’m also hoping the new 185.2 has been brought upto current standards.
