On Thursday Abby's dad came to visit Rata.
He is a train driver.
He is a community superhero because he makes sure that people safely get to where they want to go.
Lots of people need to travel by train.
Lots of things are put on freight trains.
We have to make sure that we look both ways near train tracks and we need to listen carefully too.
Because trains are very heavy, they take a long time to stop.
