Rheneas has been called a "gallant old engine" before and deserves such a title. Rheneas is highly determined, brave, courageous, and long-time friend of Skarloey. He is a tough, committed worker despite his age and takes great responsibility in his work. He is keen to keep his friends smiling and, although he is a level-headed engine, he can be a bit of an adventurer too. Though he may often try to struggle on alone, Rheneas knows when it is time to call on the help of his friends. Nevertheless, Rheneas is always highly dedicated to the task at hand.
