ulmer94: Thanks for asking about the smoke..The first thing you have to do download #242 Renfe Engine, because it has the smoke you want..You can download it from Trensim.com..The next thing after you downloaded is to open the file of the Renfe Engine(Edit through explorer)..The first page you see, Hi-lite The "humoconderada.tfx" and copy..Now go to the file of the engine(Ben Neal's Baldwins) and the very first page you see Paste "humoconderada.tfx..now open up con fig file and find "Stack.tfx", change it to read "humoconderada.tfx"..Then go back(Edit through Explorer) save and commit it..Good Luck and let me know if it works OK for you..
