MTH's Aerotrain is a unique and popular set enjoyed by many O-gaugers but since it's a RailKing engine it lacks the things some of us enjoy such as smoke and having more motive power.
I've heard that some owners have modified their Aerotrain engines by adding a smoke unit, a larger rear motor, or both.
If you've done these mods or any others to your engine, please share your results with the rest of us explaining in detail how you did them along with the part numbers you used and pictures or videos showing your mods and the results you achieved.
