Ernest is the Number 2 on the Culdee Fell Railway.
Ernest was built in 1895 along with Godred and Wilfred in Winterthur, Switzerland. After completion, he had a few tests on a Swiss mountain railway, and then arrived on Sodor in 1900. After Godred's accident, he became the oldest member of the engines. He was the first engine to have in overhaul, which took place in 1951. He had another one in 1990, though this time at Crovan's Gate.
The Jonateers model of Ernest will be used in The Slopes of Culdee Fell.
Ernest is based on the Snowdon Mountain Railway's Enid. When Thomas1Edward2Henry3 visited the railway in June 2015, this was the engine that pushed the coach to the summit.
Like the other Culdee Fell Engines, Ernest only appeared in Mountain Engines. However, his face was not shown, only the back half of him.
- In The Slopes of Culdee Fell, he speaks with a Southern accent.
