“MANY OF THE NECESSARY DEVICES OF OUR MODERN WORLD ARE OPERATED BY REMOTE CONTROL. EARLY ILLUSTRATION OF THE MARIONETTE DANCERS IS USED, THEN ACTION PROGRESSES TO MODERN TRAFFIC CONTROL, & THEN TO THE AUTOMOBILE WITH THE VACUUM GEARSHIFT DRAMATIZED.”
NEW VERSION with improved video & sound: https://www.youtube.com/watch?v=hu8SrcOeDZU
Public domain film from the Prelinger Archive, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied.
The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

https://en.wikipedia.org/wiki/Marionette
A marionette is a puppet controlled from above using wires or strings depending on regional variations. A marionette’s puppeteer is called a manipulator. Marionettes are operated with the puppeteer hidden or revealed to an audience by using a vertical or horizontal control bar in different forms of theatres or entertainment venues. They have also been used in films and on television. The attachment of the strings varies according to its character or purpose…
Marionettes are sometimes referred to as “puppets”, but the term “marionettes” is more precise, distinguishing them from other forms of puppetry, such as finger, glove, rod and shadow puppetry…
https://en.wikipedia.org/wiki/Railroad_switch
A railroad switch, turnout or [set of] points is a mechanical installation enabling railway trains to be guided from one track to another, such as at a railway junction or where a spur or siding branches off.
The switch consists of the pair of linked tapering rails, known as points (switch rails or point blades), lying between the diverging outer rails (the stock rails). These points can be moved laterally into one of two positions to direct a train coming from the narrow end toward the straight path or the diverging path. A train moving from the narrow end toward the point blades (i.e. it may go either left or right) is said to be executing a facing-point movement.
Unless the switch is locked, a train coming from either of the converging directs will pass through the points onto the narrow end, regardless of the position of the points, as the vehicle’s wheels will force the points to move. Passage through a switch in this direction is known as a trailing-point movement.
A switch generally has a straight “through” track (such as the main-line) and a diverging route. The handedness of the installation is described by the side that the diverging track leaves. Right-hand switches have a diverging path to the right of the straight track, when coming from the narrow end, and a left-handed switch has the diverging track leaving to the opposite side.
A straight track is not always present; for example, both tracks may curve, one to the left and one to the right (such as for a wye switch), or both tracks may curve, with differing radii, while still in the same direction…
https://en.wikipedia.org/wiki/Traffic_light
On 10 December 1868, the first traffic lights were installed outside the British Houses of Parliament in London, to control the traffic in Bridge Street, Great George Street and Parliament Street. They were promoted by the railway engineer J. P. Knight and constructed by the railway signal engineers of Saxby & Farmer. The design combined three semaphore arms with red and green gas lamps for night-time use, on a pillar, operated by a police constable. The gas lantern was turned with a lever at its base so that the appropriate light faced traffic…
The first interconnected traffic signal system was installed in Salt Lake City in 1917, with six connected intersections controlled simultaneously from a manual switch. Automatic control of interconnected traffic lights was introduced March 1922 in Houston, Texas.[13] The first automatic experimental traffic lights in England were deployed in Wolverhampton in 1927. In 1923, Garrett Morgan patented his own version. The Morgan traffic signal was a T-shaped pole unit that featured three hand-cranked positions: stop, go, and an all -directional stop position. This third position halted traffic in all directions to give drivers more time to stop before opposing traffic started. Its one “advantage” over others of its type was the ability to operate it from a distance using a mechanical linkage. Toronto was the first city to computerize its entire traffic signal system, which it accomplished in 1963…
