jane-skyhook , DTG JD I put together a compilation of the four trains from TSW3 only, the GWR class 43 & 166 as well as the EMT MML version of the class 43 and the “class 158/0 as it is labeled in game” the exhaust from the four trains can be best described as a “Puzzling Purple Phenomenon!? “ Link to video is the bottom, for some reason the links are not showing properly, I removed all but the one I made. My apologies for any inconvenience. If the video is not viewable in the post, link to my channel on YT is in my Signature where it can be viewed, for some reason the I can't see the link in the post nor the image of the video. I did a fair amount of searching so as not to put this info in the incorrect thread, seeing as this info involves the recent DLC - MML EMT trains as well as the GWR / GWG Class 43 and 166 trains. I have attached video(s) showing the real trains, seeing as I have never been in the UK, I have NO frame reference other than to take to the internet.
