James Watt, a Scottish inventor and mechanical engineer, greatly improved the steam engine of Thomas Newcomen, hitherto used to pump water out of mines. Watt developed a reciprocating engine in 1769, capable of powering a wheel. Although the Watt engine powered cotton mills and a variety of machinery, it was a large stationary engine. It could not be otherwise: the state of boiler technology necessitated the use of low pressure steam acting upon a vacuum in the cylinder; this required a separate condenser and an air pump. Nevertheless, as the construction of boilers improved, Watt investigated the use of high-pressure steam acting directly upon a piston. This raised the possibility of a smaller engine, that might be used to power a vehicle and he patented a design for a steam locomotive in 1784. His employee William Murdoch produced a working model of a self-propelled steam carriage in that year.
The first full-scale working railway steam locomotive was built in the United Kingdom in 1804 by Richard Trevithick, a British engineer born in Cornwall. This used high-pressure steam to drive the engine by one power stroke. The transmission system employed a large flywheel to even out the action of the piston rod. On 21 February 1804, the world's first steam-powered railway journey took place when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren ironworks, near Merthyr Tydfil in South Wales. Trevithick later demonstrated a locomotive operating upon a piece of circular rail track in Bloomsbury, London, the "Catch Me Who Can", but never got beyond the experimental stage with railway locomotives, not least because his engines were too heavy for the cast-iron plateway track then in use.
The first commercially successful steam locomotive was Matthew Murray's rack locomotive "Salamanca" built for the Middleton Railway in Leeds in 1812. This twin-cylinder locomotive was not heavy enough to break the edge-rails track and solved the problem of adhesion by a cog-wheel using teeth cast on the side of one of the rails. Thus it was also the first rack railway.

The first steam-powered and first electric-powered model trains were both invented in Paterson. Eugene Beggs made the first steam-powered train in the city around 1871. Beggs' employee, Jehu Garlick, invented the first electric-powered model train that consisted of a tinplate toy locomotive with four aluminum wheels. "Toy World" which highlights the history of New Jersey's toy making industry at the New Jersey State Museum prominently featured Paterson's contribution to the history of toys.

Matthew Murray of Leeds built the first commercially successful steam locomotive ("Salamanca") in 1812. The Doncaster Works at Hexthorpe built Britain's most famous steam trains, for the GNR, then LNER (from 1923). The Manchester–Sheffield–Wath electric railway was the UK's longest electrified railway in 1953 when opened. What is now West Yorkshire in the nineteenth century was the heart of Britain's woollen weaving wills, often using Alpaca fiber and by connections to the important Leeds and Liverpool Canal. Joseph Bramah of Barnsley was important in the development of hydraulics, and also developed the hydraulic press in 1795 and in 1778 the flush toilet.
Joseph Aspdin from Leeds invented Portland cement in 1824; when mixed with aggregates and sand, this produced concrete. John Smeaton was a famous civil engineer from Leeds, and notable for building the first modern-day lighthouse (Eddystone Lighthouse) and for developing hydraulic lime (it is able to set under water), which would lead to cement. Sir Donald Bailey (civil engineer), of Rotherham, invented the Bailey bridge which was important in the later stages of the Second World War for crossing rivers; the design took place in 1940 at the Experimental Bridging Establishment in Christchurch, Dorset (Hampshire before 1974).

1782: The first steam-driven train is invented by Richard Trevithick in Boston, Plymouth Commonwealth. A race is held in a commonwealth bordering the New Nile starting in Springfield and ending in Cairo, with one of the hairy elephant-pulled trains they threaten to replace.

"We designed the building from the inside out, not the outside in,” said Loretta H. Cockrum, Foram’s founder, chairman and CEO. “We wanted the most efficient office building ever designed, with no wasted space or wasted energy. This is a building of the future more than a building of the present. A lot of love has gone into that building, and a lot of pride."

Sometimes inventions and ideas may seem to arise spontaneously while daydreaming, especially when the mind is free from its usual concerns. For example, both J. K. Rowling (the creator of Harry Potter) and Frank Hornby (the inventor of Meccano) first had their ideas while on train journeys.

This enzyme belongs to the family of oxidoreductases, specifically those acting on paired donors, with O2 as oxidant and incorporation or reduction of oxygen. The oxygen incorporated need not be derived from O2 with 2-oxoglutarate as one donor, and incorporation of one atom o oxygen into each donor. The systematic name of this enzyme class is N6,N6,N6-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase (3-hydroxylating). Other names in common use include trimethyllysine alpha-ketoglutarate dioxygenase, TML-alpha-ketoglutarate dioxygenase, TML hydroxylase, 6-N,6-N,6-N-trimethyl-L-lysine,2-oxoglutarate:oxygen oxidoreductase, and (3-hydroxylating). This enzyme participates in lysine degradation and L-carnitine biosynthesis and requires the presence of iron and ascorbate.

Ƨ was used in the Zhuang alphabet from 1957 to 1986 to indicate the second, or falling, tone (), due to its resemblance to the numeral 2, along with four other letters resembling numbers. (See table). In 1986, Ƨ was replaced by the similarly shaped, but fully Latin, Z, when the alphabet was simplified for use in computers.

Ŭ represents a semivowel in the orthography of Esperanto, which is an international auxiliary language publicly presented in 1887. As in Belarusian, Esperanto Ŭ is pronounced as a non-syllabic , primarily in the diphthongs "aŭ", "eŭ" and rarely "oŭ".

Ɯ was used in the Zhuang alphabet from 1957 to 1986 to represent the same vowel as in IPA; sometime before or in 1986, it was replaced with W.

The summit tunnel (Number 6), , was started in late 1865, well ahead of the railhead. Through solid granite, the summit tunnel progressed at a rate of only about per day per face as it was being worked by three eight-hour shifts of workers, hand drilling holes with a rock drill and hammer, filling them with black powder and trying to blast the granite loose. One crew worked drilling holes on the faces and another crew collected and removed the loosened rock after each explosion. The workers were pulled off the summit tunnel and the track grading east of Donner Pass in the winter of 1865–66 as there was no way to supply them, nor quarters they could have lived in. The crews were transferred to work on bridges and track grading on the Truckee River canyon.
In 1866 they put in a vertical shaft in the center of the summit tunnel and started work towards the east and west tunnel faces, giving four working faces on the summit tunnel to speed up progress. A steam engine off an old locomotive was brought up with much effort over the wagon road and used as a winch driver to help remove loosened rock from the vertical shaft and two working faces. By the winter of 1866–67, work had progressed sufficiently and a camp had been built for workers on the summit tunnel which allowed work to continue. The cross section of a tunnel face was a , oval with an vertical wall. Progress on the tunnel sped up to over per day per face when they started using the newly invented nitroglycerin—manufactured near the tunnel. They used nitroglycerin to deepen the summit tunnel to the required height after the four tunnel faces met, and made even faster progress. Nearly all other tunnels were worked on both tunnel faces and met in the middle. Depending on the material the tunnels penetrated, they were left unlined or lined with brick, rock walls or timber and post. Some tunnels were designed to bend in the middle to align with the track bed curvature. Despite this potential complication, nearly all the different tunnel center lines met within or so. The detailed survey work that made these tunnel digs as precise as required were nearly all done by the Canadian born and trained Lewis Clement, the CPRR's Chief Assistant Engineer and Superintendent of Track, and his assistants.
