3 rail fun, lots of smoke, set a building on "fire" 

Smoking grain elevator is pretty cool looking. I've been admiring the smoking switch towers recently.

If that bld is full of grain it will be hard to put out 👩🏻‍🚒🚒lol, yes I agree on how much smoke brand new engine I put like 10 drops let wit soak up for a while then add a couple drops as I run yes u put to much u will get everywhere I have done it 👍 awesome fire burning 🔥
