Uray is one of the engines that created by Stuingtion. He is very strong lifter and hauler, despite being small. He also has a very powerful magnet crane on his back. He can also climb walls and go off tracks due to his four front wheels having magnets and suction cups on them. He is one of the only train to use nuclear power due to uranium rods having qualities like the fuel on his home planet, but his fuel has to be heavily guarded because many people wanted to steal it for greedy uses and dangerous uses.
- Uray comes from the planet Uranus.
