After playing and enjoying the RHTT Class 66, I have noticed a couple of issues which although minor, could benefit from a fix. The problems are... The windscreen wipers seem a little loud when operating. The horn sounds somewhat puny and could do with a more forceful sound (I believe common to all versions of Class 66). After switching on the DSD in the fuse box, upon sounding, it is not possible to cancel the DSD Vigilance alarm with the AWS/DSD button (Circle button on PS), instead you have to look at the foot pedal and press X which takes longer. I hope these items can be remedied by the team for an even better experience. Thanks DTG.
Workaround: Just don't turn on DSD until DTG fixes this problem. It's like the SIFA on KWG DB BR 185 before the latest update.
