Assume all other forces on the train are balanced. Which statement describes the forces on the train?

 - The forces are unbalanced, so there is a net force on the train.
 - The forces are balanced, so there is no net force on the train.
To determine if there is a net force on the train, look at the forces:
Earth's gravity is pulling the train down with a force of 200,000 N.
The magnetic track is pushing the train up with a force of 200,000 N.
The forces are in opposite directions, and the forces have the same magnitude: 200,000 N. This means that the forces are balanced, so there is no net force on the train.
