The Dinorwic Alice Class is a class of eleven narrow-gauge {{whyte|0-4-0|ST}} steam locomotives built specifically for the Dinorwic quarry. These locomotives were built by the Hunslet Engine Company between 1886 and 1904, and were designed and supplied specifically to work the many galleries of the quarry at Llanberis, North Wales.
History
File:Dinorwic (Charlie) works photo.jpg of Dinorwic, the forerunner of the Alice class]]
After earlier experiences with vertical boilered De Winton locomotives, the quarry company decided they needed more powerful locomotives to run on heavier, double-headed rail in chaired track on its more intensively worked quarry galleries. To improve transport of cut slate to the mills and waste to the slag tips, a standard locomotive design that was powerful, lightweight and had a short wheelbase was required.{{cite book| author=Thomas, Cliff|title=Quarry Hunslets Of North Wales.| publisher=Oakwood Press.| year=2001|isbn=0-85361-575-6}}
In 1870, the quarry placed an order with the Hunslet Engine Company of Leeds for a prototype locomotive. They produced Dinorwic (works number 51 of 1870), which is a clear precursor to the Alice class. This locomotive proved a success and two further locomotives were ordered in 1877 to an improved design.
Hunslet continued to evolve the design, and when the quarry ordered a fourth locomotive in 1886, Hunslet delivered the first of the Alice Class engines, named Velinheli (No. 409 of 1886). The class name was derived from the second example of this class of engine to be built, named Alice later King Of The Scarlets (No. 492 of 1889). This was done to avoid confusion with the Port organisation (Port Dinorwic or Y Felinheli) which was separate from the quarry operation.
11 locomotives of this class were built for the Dinorwic Slate Quarry, with all surviving into some form of preservation. Hunslet allocated the telegraphic codename VELIN to this class, named after the first locomotive.
