Rheneas is a wise old narrow gauge engine.
Rheneas is an old, yet lively red engine who works on the Skarloey Railway. He is brothers with Skarloey, and twins with Dolgoch, who workes on the Tallynn Railway.
When he and Skarloey first arrived on Sodor, they went through many mishaps before becoming truly enterprising engines, but one hundred years later they are one of the most respected engines on the Skarloey Railway. They are seen as the elders of the fleet and keep all the other engines on task and in good working order.
