Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon.
A geared steam locomotive is a type of steam locomotive which uses gearing, usually reduction gearing, in the drivetrain, as opposed to the common directly driven design.
A tank locomotive or tank engine is a steam locomotive that carries its water in one or more on-board water tanks, instead of a more traditional tender. Most tank engines also have bunkers to hold fuel; in a tender-tank locomotive a tender holds some or all of the fuel, and may hold some water also.
Beamish Museum is the first regional open-air museum, in England, located at Beamish, near the town of Stanley, in County Durham, England. Beamish pioneered the concept of a living museum. By displaying duplicates or replaceable items, it was also an early example of the now commonplace practice of museums allowing visitors to touch objects.

A stamp mill is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation.
The LNER W1 No. 10000 was an experimental steam locomotive fitted with a high pressure water-tube boiler. Nigel Gresley was impressed by the results of using high-pressure steam in marine applications and so in 1924 he approached Harold Yarrow of shipyard and boilermakers Yarrow & Company of Glasgow to design a suitable boiler for a railway locomotive, based on Yarrow's design.
Stephen Lewin was an English architect, artist, civil engineer and an iron-founder, who was a builder of steamboats and steam locomotives.

The River Wear in North East England rises in the Pennines and flows eastwards, mostly through County Durham to the North Sea in the City of Sunderland. At 60 mi (97 km) long, it is one of the region's longest rivers, wends in a steep valley through the cathedral city of Durham and gives its name to Weardale in its upper reach and Wearside by its mouth.

During the 19th century, it was mined for its ornamental value, and mining continues on a small scale.
The Hetton Colliery Lyon or Lyons is an early British steam locomotive that still survives in preservation. It is remarkable for having continued working into the early 20th century.
