I think it would be fabulous if someone could make a fully functional DB BR 155, to run on RSN, that includes sounds when it goes through tunnels, when on the PS4. Somebody did try to make a DB BR 155 a couple of years ago, but they were complete and utter amateurs, and didn't even test their loco in the tunnels on RSN (of which there are quite a few). So - if there is someone out there with a little bit more skill - someone with the imagination to realise that trains can make noise in tunnels - and they want to build a fully working DB BR 155 - then they would get my full support. It would be a great addition to TSW - and then the current DB BR 155 could be withdrawn from sale.
