Snowploughs are devices used by the engines to clear snow from the tracks as they pull their trains during winter. They are usually fastened onto the engine's front buffers, and push snow aside when the engines charge through the snow blocking the line. Most snowploughs are painted in the colour corresponding to their engine's livery.
Some engines are known to hate their snowploughs and find them uncomfortable, such as the case with Thomas.
- To date, Victor is the only narrow gauge engine to wear a snowplough.
