I've been trying to figure out how to add an easy-access staging yard to our modular layout, and this crossover wye module set is one possibility. It conforms to the modular standard (bottom connections), and would allow access to staging yards (top connections) from the centre of the layout.
The geometry was a nightmare to figure out, and it only works for PF track. I had to use a few segments of (unflexed) flex track, and the gaps between track segments are too large to maintain 9V connectivity.
The nice thing about this wye (and the main reason the geometry was so tricky) is that the top connections also conform to the standard, so standard yard modules can be used as the staging yard.
A crossover study (also referred to as a crossover trial) is a longitudinal study in which subjects receive a sequence of different treatments (or exposures).
I don't talk to flowers, they talk to me and I gladly listen!
These looked deliciously regal, I needed to do something different... more special with them?
Difficult subjects. A REAL TREAT LARGE and View On Black
Who said do not work with children and animals? Please can you add flowers for meeeee, ha ha!
For years I 'experimented' in the studio, to get that Flemish painter's light? Well, I was born in Flanders, it must be in my blood? LOL.

Why not view the set as a slide-show?
Also I often upload more than one image at the same time, I see a tendency to only view the last uploaded...
At one time, mechanical signalboxes (just about all but the most basic block posts) had a trailing crossover, to facilitate planned and emergency wrong line running. In addition, many of them - like this box at Derwent Junction, Workington - were used for routine operations.
Although switched out for the back shift in its final decade of operation, this signalbox was busy on morning shifts with traffic into and out of the docks branch and the nearby West Cumberland siding. Up coal trains for the docks would back from the up to the down main over the crossover and also - as here - it was used for other docks traffic. In this case covhops containing Hydrated Calcium Sulphate or perlite (a volcanic glass similar to gypsum used in the plaster industry) are seen on the crossover under the control of 31446. This picture is dated June 1988, five months before the closure of the box.

GECX 2035 rolls north through the Duplainville Interlocking. Just like the crossover in the foreground, this engine is the beginning of GE's attempts at crossing over the nation's motive power from Tier 3 to the 2015 Tier 4 regulations.
Aixam-Mega is one of the largest manufacturers of very small cars that can be driven without driving license. Maximum speed of these cars is limited to 45 km/h (28 mph). This one is called Crossover, more or less a Wagon version with more rugged looks. It's powered by a 400 cc 2-cylinder diesel engine.
I spent a fun-filled-waterfallin' 3 days last week in and around Ricketts Glen State Park.
I met up with flickr friend Truman, who is pictured above. I've been very fortunate to meet many great people through flickr....it's a pretty cool thing. Making the crossover from virtual world to real world can be dicey...Tru is a quality guy who has great talent and vision. I'm glad we had the opportunity to spend some time and share a few laughs...and look forward to meeting up again some time. I look forward to seeing some of his images...hint hint!

St. Paul, Minnesota
At least they were smart enough NOT to pave over this part of the streetcar line. Those are electrically powered, remote control switches, just like model railroaders have been been using for decades. You can see the route has been set for a train departing St. Paul, to make sure it's on the RIGHT hand side of the line when going to Minneapolis. No left hand running allowed in the US of A.

A pair of Caterpillar 336E excavators lift a new pre-assembled section of railroad track crossovers into place on the west end of the Connellsville CSX Yard. The amount of weight these excavators can lift is impressive.
An outbound (N) train crosses onto the local track just north of Kings Hwy Station. The southbound platforms of the stations north of here are closed for reconstruction, so southbound trains are using the northbound express track to bypass the construction.

Sometimes these gelatinous tubes of little beads seen in Wellington Harbour would encounter one another briefly and then continue on their way. Accoding to the Dom Post, these are called salps: www.stuff.co.nz/environment/101003566/beaches-turning-to-...
Near the beach in Ancoradoiro, you get a nice view of the Ria de Muros and the Atlantic Ocean, along with the typical rocky coastline. This cross serves as a reminder that the ocean is also dangerous despite its beauty. It reads "Friend and partner, you are now in the sea that you so loved. Now tell us- what is there beyond the stars?"

I decided to revisit this scene previously shot during the day for a little look-see. Anyway I can't help but wonder if there is a better angle on this. We'll see when it's warm enough to do so. Brzzzz... Gotta get back to the car. I'm starting to know why they call this the Windy City. One would think that a native Ohioian would be somewhat use to this kind of weather by now. NOT!

Mike Pianta's solution for motorising the double crossover got me thinking:
www.flickr.com/photos/scruffulous/albums/72157705092921234
The problem with his solution is that it's lineair; to get from 'both straight' to 'both branching' you would have to slide the length of the key. So I thought, there must be a rotary way to do the same thing. Today I finally got around to playing with this idea and this is what I've got. It's not complete, I haven't done anything about RCX control, but the concept works.
The curved slopes are what's pushing the actual points, rotating the axle is what moves the contraption through its 4 states.
As pictured both sliders are pulled in by the elastic bands, so both points are straight. Turning the axle 90 degrees either way makes the dark grey cams push one of the sliders out to make that side branch. Turning the axle 180 degrees from its current position makes the light grey cams push both sliders out together.
For RCX control I'm thinking knob-wheel + touch sensor or rotation sensor to make the motor turn the axle 90 degrees at a time but I'm not sure how to initialise it...
My landscape and track sections use a combination of MILS and PennLug with the track 2 bricks above the baseplate. Annoyingly that's one plate too low to run the axle below the points to control both halves at the same time...
