[Thomas]

we all strive to make our railroads look and sound  more realistic  can a few people please help me out  q#1: can you install smoke units into the THOMAS range steamies  q#2: can you record your own sounds into sound decoders  and q#3: how much would it cost: mega bucks or pretty cheap

1. With heavy modification a smoke unit will fit in...
2. With a Loksound decoder I believe its possible to download sounds onto it or something but don't quote me on that.
3. http://www.loksound.de/us/index.php?showId=113 http://www.loksound.de/us/index.php?showId=47
