Wild amounts of future shock in this 1813(!) print (British Museum). As much as I'm aware that early steam technology was developed in the 18th century, it's surprising to see a locomotive in 1813! It depicts a coal miner in Yorkshire, and the structures in the background with chimney are probably (even earlier technology) Newcomen engines, used for pumping out mines.

The museum is back open, and I booked a ticket to visit it yesterday. Admission is free but they’re still limiting visitor numbers, so you need to arrange a timeslot in advance.
Among the museum’s many artefacts exhibiting Scotland’s industrial heritage are not one but two (2) beam engines. The first photo depicts the Boulton and Watt engine, designed by James Watt himself (Boulton was his business partner; Watt supplied the designs, Boulton the manufacturing). It’s one of the oldest surviving beam engines in the world, having been made in 1786 for pumping water at a London brewery. Later adaptations made it capable of grinding barley as well.
The other three pictures show the Newcomen atmospheric engine. This was also built for pumping water, in this case out of the mineshafts at Caprington Colliery in Ayrshire. A lot of beam engines (like, a lot) were made for this purpose at various mines around the world. Although it’s of an older and less efficient design than the B&W engine, it’s actually younger; this particular engine was probably made around 1811 to replace an earlier engine on the same site. A few cutaways in the stonework give you a better view of the engine inside its house, though the one that shows you most of the beam itself is best viewed from the next gallery up, which is currently still closed.
Much of what has been written is curiously impersonal and therefore unreal. It is as though the technologies were developed by a Deus Ex Machina, or by a corporate act representing the will of a whole people. Between 1760 and 1860, a small group of men transformed the face of England, and brought about an economic and social upheaval so vast that the life of no person in this country remained unaffected by it. They set in motion a process of rapid evolution which, spreading round the world, created international problems with which we are still vainly grappling.

Rindenboot, Teelicht und ausgeblasenes Ei
Ich besuche die Newcomen Engine im Black Country Living Museum bei Wolverhampton. Aus dem Bericht im Lesemaschine-Blog:
"Weil wir nicht den ganzen, sondern nur einen halben Tag Zeit hatten (...) warfen meine Mitreisenden nur einen Blick durch die Tür in den Raum, in dem eine working replica der nur ein paar Kilometer weiter erfundenen Newcomen Engine steht. Sie füllt ein ganzes Haus, das so aussieht. Manchmal läuft sie auch. Das sieht dann so [nicht rechtzeitig im Internet Archive gesicherter und deshalb toter Link] aus. An diesem Tag stand sie jedoch still, und im Inneren des Hauses war ungefähr das hier zu sehen, nur viel mehr davon. Die Newcomen Engine wirkt wie vom Dorfschmied aus alten Zinkbadewannen zusammengeklopft, was im Großen und Ganzen den Tatsachen entspricht. Sie ist ein enormes Ding in ihren Ausmaßen wie in ihren Auswirkungen. Ich betrachtete sie eingehend und las alle Tafeln durch, falls ich eines Tages in eine Zeitmaschine geriete und dem Mittelalter die Dampfmaschine erklären müsste. Man will dann ja nicht nur mit Rindenboot, Teelicht und ausgeblasenem Ei dastehen. Den Tafeln war zu entnehmen, dass der Kolben sich in der Newcomen-Engine wieder zurück in die Ausgangsposition bewegt, weil man kaltes Wasser in den Zylinder spritzt. Heute gibt es dafür elegantere Lösungen, ich weiß zwar noch nicht, welche, aber gebt mir ein paar alte Badewannen und einen Dorfschmied, dann kommen wir klar, das Mittelalter und ich. Ich lief den anderen nach und sagte: 'Das ist das Internet von damals! Und ihr geht einfach so dran vorbei!'"
