Rheneas is the Skarloey Railway's second engine.
Rheneas was built by Fletcher, Jennings, and Co. at Whitehaven and arrived on the Skarloey Railway in 1866.
Unlike Skarloey, Rheneas was stern and thoughtful and fell out with Skarloey after he called him a "stick-in-the-mud" following an argument over cabs. The two reconciled after Rheneas saved Skarloey from a landslide.
Rheneas literally saved the railway by keeping service through a very lean period in the late 1940s. By 1950, Skarloey was in need of repairs, leaving Rheneas to run the line. He managed to pull a full train home one rainy day despite jammed valve gear and was rewarded with an overhaul. His overhaul took place in 1961 and was returned to the Skarloey Railway soon after.
