Lilian is a 0-4-0ST 'Quarry Hunslet'. Lilian worked for most of her life at Port Penrhyn and was built by the Hunslet Engineering Company of Leeds in 1883 as No. 317. She was rescued by Nigel Bowman in 1965, and was then restored by him. She was moved to the line when it opened in 1983, and has had air brake equipment and a new boiler fitted, and an alteration of gauge since arriving.
Covertcoat is a 0-4-0ST 'Quarry Hunslet' built in 1898 by the Hunslet Engineering Company of Leeds as No. 679 and is named after the racehorse which won the Grand National in 1913 (she was previously named 'The Second' as she was the second of a batch of locomotives). She worked in the Welsh Slate Quarries at Dinorwic before being sold to enthusiast John Butler, who kept her for 20 years before sale to the Launceston Steam Railway in 1984. Her cab is a replica of the type fitted to some of the 'Quarry Hunslets', while her tender was constructed at the railway to allow footplate crew more room to move about.
Over the winter of 2006/7, a new boiler and saddle tank were manufactured for Covertcoat. For more information see here.
Velinheli is a 0-4-0ST 'Quarry Hunslet' (Alice class) built by the Hunslet Engineering Company as No. 409 in 1886. She worked in the Welsh Slate Quarries at Dinorwic before being sold to Armstrong Evans near Launceston. She was then rebuilt by James Evans for use on the private Inny Valley Railway. When this closed in 1986 she was moved to Launceston. Velinheli is privately owned by James Evans.
Dorothea is a 0-4-0ST 'Quarry Hunslet' built by the Hunslet Engineering Company as No. 763 in 1901. Her working life was spent at the Dorothea Slate Quarry in North Wales, where she worked until around 1938. After being abandoned for 30 years in a collapsed shed she was rescued by enthusiast Dave Walker in 1968. She was moved to Launceston as a pile of components in the 1980s and bought by Kay Bowman in 1989. The restoration of Dorothea was considered impossible by many experts (including Kay's husband), however, an award winning restoration was completed of Dorothea by Kay in 2001, although using Covertcoat's boiler and saddle tank. She will enter full time passenger service when her full restoration is complete.
Perseverance is a small, single cylinder vertical boilered steam locomotive built by C. Parmenter at the railway in 2004. It is constructed out of various "odds and ends" on a Hudson chassis.
This is one of the numerous 'Simplex' locos, built by the Motor Rail and Tramcar Co. of Bedford in 1933 as No. 5646. It is fitted with a 4-litre twin-cylinder Dorman diesel engine, with transmission by a Dixon-Abbot gearbox and roller chains.
There is also another earlier Simplex loco at the railway, although it is currently engine-less and requires major restoration.
This is a lightweight inspection trolley running on batteries. The wheels were once used on a brick kiln trolley, whilst the motor is an old dynamo from a boat engine. Control is achieved by controlling armature and field current, full speed is given by field weakening. The shunt-wound motor runs on 28 volts provided by nickel-iron accumulators. It's maximum speed is 18mph.
This is a slightly more heavy duty inspection trolly, constructed on the chassis of a Baguley open carriage (ex. Alton Towers) in 2004. Originally the dilly was powered by a generator, but a Kubota engine was delivered and fitted in Autumn 2004. The dilly is built so it can provide a power source for use on the railway away from mains power - this enables welding and other maintenance tasks to be achieved more easily than before.
