No, it is not safe to flatten a penny on a train track. It is illegal to tamper with railroad tracks, and it is also dangerous. The force of a train can cause the penny to shatter, sending shards of metal flying. This could seriously injure or even kill the person who is flattening the penny, or anyone else who is nearby.

In addition, even if the penny does not shatter, it could still cause damage to the train’s wheels. This could lead to a derailment, which could result in serious injuries or even death.

For these reasons, it is never safe to flatten a penny on a train track. If you see someone doing this, you should report it to the authorities.

Here are some additional safety tips:

• Never trespass on railroad property.

• Stay away from railroad tracks, even when a train is not present.

• Be aware of your surroundings when near railroad tracks.

• Listen for the sound of approaching trains.

• Never cross railroad tracks in front of an approaching train.

• Always use a designated crossing when crossing railroad tracks.

By following these safety tips, you can help to prevent accidents and injuries.
