“People come from all over the world to see us but we've never been anywhere."
"We wish we could see the world like you, Thomas. We don't even know what it's like. We can only imagine how amazing it must be!”
―Marcia and Marcio

Thomas and the Forest Engines is the fourth episode of the twenty-fourth series.


In Brazil, Thomas meets Marcia and Marcio, two wood-burning engines who have never travelled beyond their eucalyptus railway. Thomas agrees to swap jobs with them for the day, but this causes more trouble than he expects. Thomas finds that the eucalyptus railway does not give him as much room to travel as he would have liked, and his two new friends find that there is a reason why they are best suited to their short eucalyptus railway—they have a small fuel supply. They keep having to borrow from their delivery of eucalyptus wood to continue on, but they still end up stranded. Eventually, Thomas finishes work and, knowing that Marcia and Marcio should have returned by then, sets out to look for his new friends. Eventually, he finds them and brings more eucalyptus wood from their railway. The three of them finally manage to make the delivery to the docks.
