Two former Santa Fe SD40-2's, BNSF 1747 and 1739, lead a transfer job past the Old Union Depot Interlocking tower in Kansas City, MO. I had wondered why the tower said "Union Depot" when it is nowhere near Union Station, and today I learned why. This is the site of the original Kansas City Union Depot, which was replaced by Union Station in 1914. Kansas City outgrew Union Depot and there was little room to expand, which was in part why the new Union Station was built.
A long time before anyone would have considered this a "merger" consist (and what a stupid idea, these railroads are already to big to be managed properly but I digress) a 335 bangs across the diamond crossing with the former Western Railway of Alabama in downtown Opelika. Much has changed here at "the interlocker" since this hot August afternoon 15 years ago; Macon to Sheffield trains 334/335 were re-routed off the Central of Georgia over a decade ago and those Southern-era signals were replaced when CSX installed PTC back in 2017. But the stately tower of Lee County's historic courthouse in the background still stands and although traffic is down trains still roll across the Central every day.
Back in 2010 those UP Aces were still the new power and looked pretty sharp, it's a shame how ragged most of them look now. Of course that trailing NS Gevo probably looks terrible in the current day too, not that it has ever been a unit of any interest.
Photo 2 of 2 showing New York Centrals Sloan, Indiana tower, known as "NX". I'm not exactly certain when these were taken, but I would say late 40's, early 50's judging by the car in the shots. Below is some information I have on this tower and location. By the time I 1st visited Sloan in the 1980's, this was just a passing siding with an abandoned elevator.
NYC Sloan, Indiana Tower
Distance from Indiana Harbor: 94.10
Distance from Chicago: 113.70
Crossing of the NYC and the IC's former Havana, Rantoul & Eastern line
IC removed in 1943
Call Sign: "NX"
Beginning of Double track southward
Water Station
Communicating Station
Manual Block Station
Open day and night
Siding Capacity: 77 cars
Installed: 1903 (CI&S)
Removed: Sometime between 1959 and 1961
Double-track to Danville from here was removed at around the same time and replaced with a siding just short of 2 miles long
Below are some good links on the IC (nee-Havanna, Rantoul & Eastern) which crossed here. These photos don't show it there, so I'm assuming they are taken after 1943. The line ran from Rantoul, Illinois to West Lebanon, Indiana.

Notes: There are no interlocking signals here, so this was just a Manual Block Station at this time.
Switches are all handthrow.
Rods coming out of the tower only lead to train order signal and the rest of the area has been capped off.
In my 1939 NYC timetable, it shows no crossing at grade here.
In 1903 the New York Central Railroad line through Jordan Township was completed, and on June 18, 1914, a post office was established next to the railway at the township's southern edge. Named for the local Sloan family, it operated until November 29, 1941. The railroad, which by the time of its closure was owned by Conrail, ceased operations in the 1990s, and the tracks have since been removed. No structures remain at the site.--WIKI
Still wishing to see my family for the holidays. Plane tickets are so expensive :( Nothing like a £70 ticket from London! EasyJet needs to come to the other side of the pond :D

On August 28, 1989, just a few days after Clee's retirement, we got word of a southbound inspection train coming down the CE&D. It was a gray and hazy day, but you've got to do what you've got to do. Operator Bobby McClara is coming down the steps for the rollby.
After the southbound train passed, we heard that there was a track geometry train coming north after meeting the inspection train. So we decided to hang out and wait, and ended up with a HUGE surprise.
Metra F59 97 leads the way of an outbound Heritage Corridor commuter as it crosses the Chicago River. Note the full moon and the cool drawbridge making the scene.
The Giant's Causeway is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic eruption around 50 to 60 million years ago. It was declared a World Heritage Site by UNESCO in 1986.
"The tops of the columns form stepping stones that lead from the cliff foot and disappear under the sea. Most of the columns are hexagonal, although there are also some with four, five, seven or eight sides. The tallest are about 12 meters (39 ft) high, and the solidified lava in the cliffs is 28 meters (92 ft) thick in places.
During the Paleocene Epoch, highly fluid molten basalt intruded through chalk beds to form an extensive lava plateau. As the lava cooled, contraction occurred. Horizontal contraction fractured in a similar way to drying mud, with the cracks propagating down as the mass cooled, leaving pillarlike structures, which also fractured horizontally into "biscuits". In many cases, the horizontal fracture resulted in a bottom face that is convex, while the upper face of the lower segment is concave, producing what are called "ball and socket" joints. The size of the columns was primarily determined by the speed at which lava cooled. The extensive fracture network produced the distinctive columns seen today."

Cosmos bipinnatus, commonly called the garden cosmos or Mexican aster, is a medium-sized flowering herbaceous plant native to Mexico. The species and its varieties and cultivars are popular as an ornamental plant in temperate climate gardens. It naturalized in scattered locations across North America, South America, the West Indies, Italy, Australia, and Asia, where it is a garden escape (introduced species) and in some habitats becoming a weed.
Cosmos bipinnatus is considered a half-hardy annual, although plants may reappear via self-sowing for several years. The plant height varies from 2–4 ft (0.61–1.22 m). The cultivated varieties appear in shades of pink and purple as well as white. Its foliage is finely cut into threadlike segments. When flowering, the plant can become top heavy. This problem is alleviated when grown in groups, as the bipinnate leaves interlock, and the colony supports itself.

An interlocking mechanism for Romsey’s lever frame. A few visitors have asked at exhibitions whether I could add it, so I thought it would be a fun challenge. Interlocking prevents unsafe or conflicting movements through the junction. Drive bars are black and the grey slopes are the ‘dogs’ that engage with the locking pins on the yellow locking bars. 3 locks are included, although more could be added, as it’s modular.
1) Lever 7 (Down Main Points) locks lever 8 (Up Points), so you can’t send an up train across to the branch if the points are set to allow a train to cross the junction on the main
2) Lever 8 (Up Points) releases lever 16 (Up Branch Starting Signal) so you can’t pull the signal until the points are set correctly for the branch
3) Lever 18 (Up Main Starting Signal) locks lever 8, so you can’t change the points if you’ve given the train the signal to start
With a rather haggard-looking GE P42DC leading, northbound Amtrak Northeast Regional passenger train #96 shoots over the Doswell, VA, diamond and past the ever-present RF&P-era interlocking tower looking as forlorn as ever on the afternoon of November 15, 2020.
A northbound Hiawatha Service train slams the diamonds at Grayland Crossing on Chicago's northwest side. Metra's Milwaukee District North Line crosses UP's former CNW "40th Street Line" here, once an important route to 40th Street Yard, but long since singled and truncated north of Cragin to serve a few industries. Interlocking piping and cranks remain hidden in the brush here- who knows how long they've been dormant for.

It is possible to make variations by changing paper ratio, adding more cubes or interlock them different way.
When the interlocking signal is pulled into the clear position the distant signal changes from yellow to green. When the interlocking signal is at stop, the distant signal shows "proceed, prepared to stop"
NS Lima District northbound crosses the former DT&I main at Morris Interlocking in Lima. The six axles make a sweet sound as they clump across the diamonds.
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?

Origami model designed and folded by Peter Stein, September 2017
The paper I used is handmade by John Gerard (wonderful paper!)
The locking mechanism is borrowed from Jeremy Shafers "interlocking rings" (he really shows two rings in his model, mine is just giving the illusion of two rings) - it was folded for a silver wedding of two friends,
wetfolded from a square piece of paper (19x19cm).
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.
Their ears & heads sort of interlock with eachother. I made it that way. :D

NS 5310 passes Morris Tower as WPBS-03 rolls through Morrisville, PA, off the NEC and onto the thorofare track and back onto CSAO rails. August 1, 2018.
Interlocking tower in Bangkok's Hua Lamphong station. The tower was built in 1971 and is going to be closed in the near future.
Cruising past the Albert Lea, MN interlocking tower, a UP general merchandise train makes good time as it works south down the Spine Line.
Passing under the endangered early 2000's installed searchlight signal cantilever at Cleveland Avenue on the KCT East-West Corridor, is KCS Train 2Y-KC101-16 on KCT Main 2. The yard job has a pair of GEVO's with 99 cars: 62 loads and 37 empties bound from the KCS Intermodal Freight Gateway at Belton, MO to UP 18th Street Yard in KCK.
Occasionally the KCS builds big blocks of UP's at IFG, and runs them all the way across the city as one big transfer like this. This move can terminate at either Neff or 18th Street, and has even gone all the way to Quindaro at least once.
Sitting in Track 109 is KCT Train 505 waiting for Central Missouri Reload to finish unloading a boxcar before tying in and dragging it and 4 other pulls back to Blue Rive Yard.
The supports for the new 4 track signal bridge are already in place here for the EBCS and WBCS, and this rarely shot signal bridge came down late in 2016
