The Skarloey Railway Sheds are where the locomotives and rolling stock of the Skarloey Railway rest. They are located at Crovan's Gate.
The sheds and rails were raised up above the standard gauge tracks and there was a 'ramp' where narrow gauge rolling stock could be transferred onto a standard gauge flatbed or well wagon.
The Engine Shed was built in 1865 as a single road brick shed, capable of holding both the railway's locomotives. For nearly a century the Engine Shed remained as built, but in 1954 a double line was laid in to enable four engines to be accommodated. By 1961, when Rheneas at last returned, the rather ramshackle ex-Goods Shed, which Skarloey and Rusty occupied, had been repaired and closed in. Later, following the rescue and rebuilding of Duke in 1969, the main shed was extended to the rear and can now hold six locomotives. Doors at the west end give access to a turntable installed in 1965.
In addition to the main sheds, there are secondary ones at Skarloey.
The original shed of 1865 was timber built and open at the base. It was designed to hold the four-wheeled coaches and brake van which were, until 1953/54, the only revenue earning passenger stock the railway had. There were, in addition, a set of six open-sided quarrymen's coaches which were stored every weekend in the Wagon shop. At an unknown date, prior to 1953, the Carriage Shed's timber footings had been replaced with slate slabs; but when the revival in the railway's fortunes began in 1954, passenger stock was increased first with open and later with bogie vehicles and further covered storage space was needed. To provide this, the Carriage and Wagon Shops were extended. This made it necessary to re-lay the main line to clear the enlarged sheds.
When the Skarloey Railway was introduced in the fourth season, the engine and carriage sheds were similar to their Railway Series counterparts; they were mirrored and the wooden part of the shed had two tracks instead of one and the sheds and rails were lowered to ground level. Across from the sheds was a standard gauge shed/shunting yard and a roundhouse. The sheds were seemingly replaced by the Depot from the sixth season onwards. There is also a two berth engine shed at Rheneas.
In the eighteenth season, similar looking sheds reappeared on a curve track right behind Crovan's Gate station, however the carriage shed is missing, the brick shed does not have a back with the rails running right through them and the wooden shed is single lined only. They do not appear to be used for resting at night.
- The Skarloey Railway Sheds are based upon the Talyllyn Railway's sheds at Pendre, Tywyn.
