I have never seen this type of building block. If you know something about it, please share your knowledge with us.
I wonder whether this system any stronger than traditional bricks. The overlap makes it seem as if it is. If the blocks were actually in contact with one another (and even connected), then it might be effective. However, since the blocks are separated by a layer of cement, isn't the wall only as strong as the cement itself?
I'm no structural engineer, and there may be something I'm not picking up on that makes this system superior. However, if it were better, why is it this is the first time I have ever come across it in over four decades of looking at old buildings?

Foreman Jim Bottoms continues his trek northward after getting permission to pass thru the "Wabash" Interlocker at Shops. I&M employees have recently been referring to the Norfolk Southern crossing interlocking using this name. I don't know if the name has been officially changed, or if I&M employees are just having a bit of rail history fun.
this is the interlock. The receiver takes up a 4x4 footprint and is two bricks high. there is a technic link made from two 1x8. technic bricks. The axle part makes the lock.
Twenty Interlocking Irregular Hyperboloidal Dodecahedra 600 units
3-fold view.
This is the first working iteration of my magnum opus wireframe project for summer 2022: a supremely complex compound of 20 irregular dodecahedra. This is the icosahedral/dodecahedral symmetry extrapolation of the compound of 8 Dodecahedra I designed a month or two ago. Here, each dodecahedron corresponds to a single 3-fold axis representing the face of an icosahedron (or a vertex of a dodecahedron). This design also illustrates the importance of scaffold construction methods: assembling a model such as this a frame at a time is simply impossible, as the innermost vertices are deeply imbedded within the model. I believe that this is the largest ever compound of polyhedral frames. Designing this model was a considerable effort- this is version 4.5, and it could really use a refold.

“K15” 25 Interlocking Tetrahedra 150 units
5-fold view.
While considering less trivial weaving variations of “K14” (see my account on Instagram for a photo of this compound), I quickly came across a weaving pattern very similar to K10, the only primary differences being the inversion of the chirality of the exterior 2-fold axial whorls and the fact that the resulting compound happened to be the other enantiomorph. At the paper proportions used for “K14,” this resulted in a rather loose construction, since the proportions here are much thinner than those of “K10.” Consequently, I figured it worthwhile to complete the compound with an additional 5 tetrahedra, which is directly analogous to what Dirk Eisner did with his compound of 4 tetrahedra. The extra tetrahedron to each 4 tetrahedra cluster is untransformed; this is, it is neither translated nor rotated nor scaled from the tetrahedron which forms the symmetry polyhedron for each four-compound. The extra five tetrahedra would be a rather trivial addition if not for the fact that the 5th tetrahedron added to each 4 tetrahedra cluster has a different weaving relationship with the rest of the model than the other 4 tetrahedra. Thus, by my definition, this compound is a composition: although it is composed of only one type of frame and one paper proportion, that frame has 2 different independent weaving relationships, so that this could be perceived as 20+5 tetrahedra. The paper proportions are now comfortably tight, although the compound is still not rigid.
Paper proportions: .875”x11”

the go-kart racing track was right beside the roller-coaster (both are now disassembled) in this abandoned amusement park
For 1000 lire (half Euro, at that time) one could race for 5 minutes. But It was never enough, and we kept spending our hardly earned "student" money.
Go-kart racing can be tricky especially if you want to finish among the firsts.
In fact, to keep high speed, you'd better push the break pedal with your left foot without releasing the gas pedal (gas pedal stays pushed down all time).
By doing so the kart slows down approaching curves but the engine doesn't lose its torque therefore you're quickly at top speed again when exiting form the curve (after releasing the breaks that is)
this is what we guys called "a tavoletta" driving stile (impossible to translate)
this way of driving is efficient but puts a lot of stress on breaks.
the go-kart track manager quickly discovered this "dirty" driving stile and, to our surprise, put an interlock between the break and the gas pedals so that the gas would automatically disengage on every break push.... and you had to rise your right foot to engage gas again
I twas a bad thing, we almost lost any interest in kart "racing"

Arbeitsgemeinschaft Berliner U-Bahn e.V.: in 1997 the Berlin Underground Museum was opened to the public. It is installed in the old signalbox of the Olympia-Stadion station.
The main element of the museum is, precisely, the old interlocking of this station. It was in service between 1931 and 1983, and controlled 616 routes and 99 signals.

12 Interlocking Wrinkled Pentagonally Distorted Dipoles 60 units 2-fold view.
Back in May of 2017, I used some leftover paper to make a model I referred to as "4 Interlocking Wrinkled Diminished Tetragonal Dipoles." This is the dodecahedral equivalent of that model. The weaving pattern is extremely simple, and I imagine that the series can be expanded to include not only the remaining Platonic solids, but most other solids as well, including Archimedian and possibly Johnson Solids. The assembly can be slightly challenging, depending upon the paper used. "Diminished" for me now connotes the implication of edge removal rather than edge transformation, and consequently, I have stricken this word from the naming of this model, as opposed to the original. The frames are a little bit loose, so I may refold this with superior quality paper in the future.

Looking out the door glass from the long gone 14th Street interlocking tower that controlled crossing rail routes near downtown Birmingham Alabama. Occasionally, a tower operator would allow a railfan inside until another crackdown on unauthorized. I could not resist taking a shot from the wrong side of the door as a L&N train passed.

In 1914 Swedish artist Anders Zorn (1860-1920), began building an open-air museum: "Zorns Gammelgård". The museum consists of around 40 wooden buildings from the 1200s to the 1700s, most of them retrieved from the villages around Mora. Almost all of them also have horizontal logs that are interlocked at the corners by notching.
The small building in the middle is a fire house. Some of the trees for the building were cut down in the beginning of the year 1237 (determined by dendrochronology - the scientific method of dating based on the analysis of patterns of tree-rings). This makes it Sweden's oldest profane wooden building.

The New Measurement Train slowly creeps past Talacre 'box working 1Q30 Derby RTC-Crewe via the world on 22 March 2018.
Talacre controlled trains in and out of Point of Ayr colliery until closure in 1993, the track on the left was originally the up slow and in it's final years of use became a long headshunt to get trains in and out of the reception sidings, on the left beyond the bridge.
A small corner is now taken up by the gas terminal for the Douglas platform a few miles out into Liverpool Bay. The rest of the site is just an industrial wasteland, rusty sidings leading to grassy heaps of rubble where buildings once stood and it's now hard to discern where the shaft stood.
Stood in this spot 30 years ago there's a pretty good chance there would be a rake of HAA's on the track with a 56 or maybe a pair of 20's, another load of black diamonds ready for the one way trip to the burners of Fiddler's Ferry.
Now, passing trains excepted, it's almost eerily quiet. And come Monday with no bells, no clunky points and long wires, and no interlocking levers, it'll be quieter still.

Giant's Causeway, Antrim, Northern Ireland.
The Giant's Causeway, located in County Antrim, on the northeast coast of Northern Ireland, is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic eruption.
The Causeway is rich in strange and beautiful rock formations having been subject to several million years of weathering, such as the Organ and Giant's Boot structures. Other features include many reddish, weathered low columns known as Giants Eyes, the Honeycomb, the Giant's Harp, the Chimney Stacks, the Wishing Chair, the Giant's Gate and the Camel's Hump.

4 Interlocking Hyperboloidal Self-Interwoven Enneacontakaienneagonal Stars 396 units 3-fold view.
I have designed a number of interlocking star compounds in the past, but this compound was specifically undertaken to illustrate a conjecture I noted not too long ago, namely that almost any convex polyhedral shape can be accommodated to modelling with polygonal stars if 3 frames weave around each other at each vertex, representative of 3 underlying edges converging at that vertex. Of course, many polyhedra have more than 3 edges joining at some vertices, but a truncation of any such vertex will result in new vertices where 3 units do in fact converge every vertex, and are therefore “modelable” using polygonal stars. By trisecting the edges of existing polyhedra, applying truncations, and using the resulting truncated shape as the basis for a polygonal compound, an enormous number of new compound possibilities are opened up. I decided to test an application of this simple conjecture upon an interesting polyhedral shape with pyritohedral symmetry, a near-miss Johnson Solid called a Pentahexagonal pyritoheptacontatetrahedron. The resulting shape has the following axial whorls: 6 dodecagons, 12 decagons, 56 hexagons, 24 pentagons, 36 quadrilaterals, and 264 triangles, by my calculations. The assembly was a bit more challenging than some of the previous polygonal star compounds I have designed, but overall I think it turned out rather well. This is quite simply a compound of four 99-sided polygon stars, which makes these the largest polygons I have ever worked with and the largest polygons (as far as I know) ever rendered in modular origami.

I folded this some weeks ago, but forgot to share it. It's a squarish variant of Alessandro Bebers "Rohre", easier to fold and as stable. I used 2:3 instead of A-sized paper and left out any unnecassary crease for a cleaner look. Double sided paper would have been nicer, but I have this wood decor paper for so long and did not find a model it suits, so this seemed to be a good candidate.

The General Railway Signal Company (GRS) was not even in existence when this 152-lever electric interlocking machine was approved for service by the Illinois Railroad & Warehouse Commission in July 1901.
The plant was operated by the Lake Shore & Michigan Southern, a New York Central, and controlled a complex junction between the joint NYC/Rock Island joint track, Illinois Central's Chicago, Madison & Northern subsidiary, and the St. Charles Air Line.
Though a complex plant, the 16th Street interlocking was a far simplified version of the non-interlocked crossing it replaced. Prior to the grade separation of the Chicago & Western Indiana and Santa Fe, the old track arrangement boasted well over 100 crossing diamonds, and was one of Chicago's major bottlenecks.
At the time it was commissioned, 16th Street Tower saw about 850 train movements in 24 hours' time.
Though the plant is no longer quite so busy today, the 1901-era Taylor machine still soldiers on in 2017, 116 years after it was built.
