The Petropolis Train Station is a train station in Petropolis. The train station is next to a railroad that leads in and out of the city to other places such as Petsburgh, and other cities just outside Petropolis. The train station was only seen in Guard Dog.
- The vegetation gives us a clue that the city is placed in a mixed-tropical zone with a warmer climate that might be typical of Southern California (since Petropolis is located in California).
- Trains have been featured in Frisky Business, Iron Mutt, and Guard Dog.
