What new gremlins await my model railroad whenever I make changes to the track and wiring?
For several months I have been weathering some of my bright and shiny Kato Unitrack using felt tip paint pens from Woodland Scenics. I paint the steel rails a brown-black color and some of the wooden crossties (sleepers in UK rail terminology) a dark brown color. That makes the track look a lot more realistic, but the paint must be removed from the top of the rails, the rail joiners, and certain parts of the switch points in order to maintain electrical continuity between the trains and track. After the paint has dried, I rub an abrasive Bright Boy along the tops of the rail, the metal portion of the Unijoiners, and the inside surfaces of the switch points.
I snap the Unijoiners back onto each piece of track and connect each weathered piece of track with my test rig. The 12 volt DC power is fed via the blue and white wires from my power supply to an unpainted S62F feeder track upstream from the items to be tested. In this case, I am testing a right hand #6 switch and a piece of curved track to make sure I have continuity. The red and black wires control the switch motor. I run the engine forward and backward on each route of the switch several times to insure a good electrical path. All of my newly painted track is tested on my work table before I install them on the layout.
I have finished painting the visible portions of my westbound (lower) staging yard, my entire mainline, passing siding, and industrial tracks. Next I must paint the visible part of my eastbound (upper) staging yard before I install it on my layout. It is easier to paint and test track before installation. Then I need to temporarily remove all the track from my layout, install Styrofoam sub-roadbed in order to elevate the track above the streams I plan to build and connect the lower and upper staging yards by a long 2% grade on my mainline.
This concludes the test of the camera and lens. This Konica Autoreflex T is the second one I own, and all shutter speeds seem good, advance, spacing, rewind all work well, and meter appears accurate. Flash is fine too. Lens is smooth, clicky and snappy. Both solid pieces of photography gear.

This photo is more of a test than anything. Ive always enjoyed shooting HDR photos. When I got the 7D, I was excited to learn it brackets shots at up to +/-3 stops. Both my previous camera's could only bracket +/-2. This is huge in terms of capturing an scenes dynamic lighting range. So I went for a photo walk this afternoon, snapping a wide range of scenes just to test out the how the camera handled shooting with HDR images in mind. Another feature I really like about the 7D and its exposure bracketing ability is not only can you shoot the 3 bracketed photos, but you can then move the AEB sequence +/- 8 stops in either direction to shoot more if needed! This photo was just 3 shots, bracketed at +/-3 AEB. Processed in Photomatix Pro 3.2 and touched up in Photoshop CS3 for a bit of sharpening and tone adjustments. It had been a while since I shot any HDR. I think i might put it to use more often now.

These are test molds from Billund, somewhere around 10-15 years ago most likely. Do these colors have actual IDs that we haven't found yet? Or were these colors never that far in the process?
The colors are metallic/pearl — maybe they are be prototypes from LEGO Friends' long development, around when 315 and 316 came out?
These bricks feel modern but don't line up perfectly with known solid colors. Maybe the metallic additive changes the color more than we think (ALL of these are at least slightly pearly, even the red).
Known in 2x4 plate, 2x4 brick, 1x2 brick, 2x2 slope, 1x4 tile, and 1x4 brick. I've also heard of one in 2x6 brick, but not seen it. 2x4 bricks have also been found in milky white and trans-blue-glitter.
Bottom of every part just says "©LEGO" and "CoC" — what could this mean?
Happy to trade tiles/slopes for 2x4 plates in the same colors :)

I was drawn to this doorway whilst walking around Canterbury. It's a shame such an old building is boarded up like this. What made me interested in the door was it looks like some sort or image on the door.
It's a bit like one of those ink blot tests, what do you see?

Alder Valley Bristol RESL comes down Station Road in Aldershot on August 23rd 1984. Judging by the incongruous blind display, it was most probably on a test run to/from the depot in Halimote Road.
Test Car 6 (TC6) was converted in the mid-1970s at the RTC Derby from one of the first production order British Rail Mk II FK vehicles (S13396), being renumbered ADB975290 with TOPS code QXA.

A well used title, but more appropriate now than ever. 37610 is pictured at Hencote with a 1215 Coleham - Coleham (via Bidston) on 22-4-20. Taken on an exercise walk from home.
Another view of the Keolis/MBTA test train led by GP40MC 1117 in sparkling fresh paint from its recent overhaul at the MBTA's Wareham shop with four cars including two MBB cars still wrapped in CTRail imagery from their time leased for Hartford Line service. They are on the causeway that cuts across Terry Brook Pond at about MP FS 4.9 just north of the Copicut Road grade crossing, but alas it is too brushed in to see the water on either side of the train.
This route into the city of Fall River opened in 1846 and saw continuous passenger service under the auspices of the Fall River Railroad and then the Old Colony system until the latter was folded into the New Haven Railroad in 1893. The NH continued daily service to Boston until September 1958 when all passenger service ended to south of Middleboro including to the famed whaling port of New Bedford. In June of 1959 Middleboro lost service along with the other former Old Colony branches to Plymouth and Greenbush. Commuter service returned to Middleboro and Plymouth in 1997 and Geeenbush a decade later but the extension south had to wait.
Fortunately both lines were never fully abandoned, and remained active as freight only branch lines served by the New Haven and successors Penn Central, Conrail, and CSXT. In latter decades they saw no more than a lonely local freight two or three days a week and both the Fall River and New Bedford Secondary's track conditions deteriorate until speeds were limited to 10 mph on the two lines that were not even an afterthought in the vast CSXT system. In 2010 the Commonwealth of Massachusetts purchased the two routes totaling 38 miles from the Jacksonville based Class for $21 million as the first step in the long dreamt of plan for a passenger train revival. Concurrent with that deal CSXT turned around and sold its perpetual freight easement to Mass Coastal which since then has provided exclusive freight service on both lines, interchanging with CSXT at Cotley Junction in Taunton. For the past decade the MC dispatched and maintained the lines on behalf of the state while they remained 10 mph branches served a couple times a week.
Finally in 2020 the transformation of the lines began in earnest at a cost to exceed $1 billion and by mid 2023 track and station work was largely completed on the Fall River Secondary include a new Freetown station about 1/2 mile behind me here. The first week of August this year Keolis assumed dispatching responsibilities from Mass Coastal once the new CTC signal system was commissioned and PTC testing and crew qualification trips have been running daily as seen here.

She will be on the body i working on now, the neck is little thicker than on the KW or DC bodies so to made a hybrid i will do some extension for the neck hole to made it possible.
Haji Lane comes alive after hours - some of the places only open at 4pm and keep crankin' until 1 or 2am - so wandering around in the daytime can be surreal.
This odd mosaic-design pattern on the pillar of an Italian-themed bar resembles the old TV test patterns that would be aired when the station was off-air.
With information overload now the norm and stations broadcasting around the clock, soon the university crowd will have no idea what a test pattern is! If you're interested, check out en.wikipedia.org/wiki/Test_card
This is the thinner .040" plastic, and the mask is pretty flimsy as a result, but not a bad proof-of-concept piece.

Nondestructive testing
Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage.[1] The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology.[2] Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), eddy-current testing,[1] and low coherence interferometry.[3][4] NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art.[1] Innovations in the field of nondestructive testing have had a profound impact on medical imaging, including on echocardiography, medical ultrasonography, and digital radiography.
Methods[edit]
NDT methods may rely upon use of electromagnetic radiation, sound, and inherent properties of materials to examine samples. This includes some kinds of microscopy to examine external surfaces in detail, although sample preparation techniques for metallography, optical microscopy and electron microscopy are generally destructive as the surfaces must be made smooth through polishing or the sample must be electron transparent in thickness. The inside of a sample can be examined with penetrating radiation, such as X-rays, neutrons or terahertz radiation. Sound waves are utilized in the case of ultrasonic testing. Contrast between a defect and the bulk of the sample may be enhanced for visual examination by the unaided eye by using liquids to penetrate fatigue cracks. One method (liquid penetrant testing) involves using dyes, fluorescent or non-fluorescent, in fluids for non-magnetic materials, usually metals. Another commonly used NDT method used on ferrous materials involves the application of fine iron particles (either liquid or dry dust) that are applied to a part while it is in an externally magnetized state (magnetic-particle testing). The particles will be attracted to leakage fields within the test object, and form on the objects surface. Magnetic particle testing can reveal surface & some sub-surface defects within the part. Thermoelectric effect (or use of the Seebeck effect) uses thermal properties of an alloy to quickly and easily characterize many alloys. The chemical test, or chemical spot test method, utilizes application of sensitive chemicals that can indicate the presence of individual alloying elements. Electrochemical methods, such as electrochemical fatigue crack sensors, utilize the tendency of metal structural material to oxidize readily in order to detect progressive damage.
Analyzing and documenting a non-destructive failure mode can also be accomplished using a high-speed camera recording continuously (movie-loop) until the failure is detected. Detecting the failure can be accomplished using a sound detector or stress gauge which produces a signal to trigger the high-speed camera. These high-speed cameras have advanced recording modes to capture some non-destructive failures.[5] After the failure the high-speed camera will stop recording. The capture images can be played back in slow motion showing precisely what happen before, during and after the non-destructive event, image by image.
