Lancashire Witch

Lancashire Witch is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Lancashire Witch rather than just read about it. In short: Lancashire Witch was an early steam locomotive built by Robert Stephenson and Company in Newcastle-upon-Tyne in 1828. It was a development of Locomotion.

Key takeaways

Lancashire Witch belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Lancashire Witch to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Lancashire Witch from memory before moving on to harder problems.

Reference excerpt

Lancashire Witch was an early steam locomotive built by Robert Stephenson and Company in Newcastle-upon-Tyne in 1828. It was a development of Locomotion.

Description Lancashire Witch was an 0-4-0 locomotive with rear mounted cylinders inclined at 45 degrees driving to the front wheels. The rear wheels were powered via coupling rods. The boiler had two flue tubes and the locomotive burnt coke, aided by bellows on the tender. It was the first locomotive with steel springs. It was the first locomotive built by Robert Stephenson and Company.

History The locomotive that was to become Lancashire Witch was ordered by the board of the Liverpool and Manchester Railway (L&MR) in January 1828. The boiler was to incorporate a series a small flues, this evolved into a large central flue and two smaller side flues bent at the end. Four months after the order, the L&MR board transferred the locomotive to the Bolton and Leigh Railway (B&LR) (which opened in June 1828) where it was used as well as the L&MR. It was initially used to construct the B&LR, where it was shown hauling 58 long tons (59 t; 65 short tons) up a gradient of 1 in 432 (2.3‰ or 0.23%) at 8.8 miles per hour (14.2 km/h).

Postage stamps Lancashire Witch appeared on two postage stamps issued by Funafuti-Tuvalu on 24 December 1984.

Other locomotives

London, Midland and Scottish Railway Royal Scot Class 4-6-0 locomotive 6125 was named Lancashire Witch in March 1928. Later that year an engraved brass plaque was added, depicting the original locomotive of 1828. The name and engraved plaque were removed in July 1935, and on 30 July 1936 a new name 3rd Carabinier was unveiled at a ceremony. The Royal Scot class loco was built by the North British Locomotive Company at Glasgow in September 1927 and withdrawn in October 1964 as 46125. Class 86 locomotive 86 213 was named Lancashire Witch. This locomotive has been preserved in operational condition by the AC Locomotive Group.

Worked examples

Example 1 — a first encounter with Lancashire Witch

Start with the simplest possible case. Write down what Lancashire Witch claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Lancashire Witch before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Lancashire Witch ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Lancashire Witch

In research: Lancashire Witch appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Lancashire Witch in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Lancashire Witch is common in secondary-school and first-year university syllabi. It links to neighbouring topics 0-4-0 locomotives, Early steam locomotives, Individual locomotives of Great Britain, so understanding it makes those chapters shorter.
In everyday life: Look for Lancashire Witch outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
