Ernest is a mountain engine and is the Culdee Fell Railway's second engine.
Ernest was built at the Swiss Locomotive and Machine Works in Winterthur, Switzerland, in 1895. He only appeared in Mountain Engines informing Culdee of the changes that happened to the railway in his absence.
He missed Culdee when he was sent to the Works to be Mended, he is a kind Engine and does try to keep his work going on time and likes to be on time in doing so. Ernest And Wilfred often work along side each other, but still like to tend to their own works and make sure that the passengers are on time and happy.
Ernest is based on the Snowdon Mountain Railway's Enid.
