How to Sign "Train" in American Sign Language (ASL)

In ASL, "train" is signed by making two fists with both hands, placing them side by side, and moving them forward together in a rolling motion, mimicking train wheels moving along tracks. This sign comes from how trains look when they move. People sometimes pull their hand above their head to show a train whistle. The sign shows up a lot when talking about getting around or going on train trips. When talking about different kinds of trains like subways or freight trains, signers add extra signs to make the meaning clear.
