- Demonstrating the Inglenook sidings switching puzzle on my PRR Grantville Spur layout.
My model railroad is a 10' x 13' HO scale shelf layout set on Long Island in the mid 1960s (give or take). Why I model the LIRR is a long story... It's pretty much done, but there's always room for improvement.

Thank you for taking the time to show this. The puzzle fits into the layout space very nicely. Well done recreation of a nice section on Long Island
Thanks for watching!
Great explanation. You have taken the hidden complications that some seem to envision with this puzzle and shown that this can be a fun, and easy op session. Cheers
Thank you! Inglenook can provide endless entertainment. When I do it normally (without filming) I don't stick the big numbers to the tops of the cars, though. Just thought I'd mention that even though it nothing to do with your comment.
What a great way to stimulate the mind a little while enjoying the layout. Thanks
Thanks for watching. It's fun to do and once you set it up the first time it's always set up and you can dive right in whenever you want.
I love shunting with wagon cards, and this video was enjoyable to watch. Beautiful trackwork too.
Thanks for watching!
Simple unless you wanted them in reverse order. BTW, try putting your wires to the turnouts in a metal tube and this will allow for longer distances without bending.
Thanks for the tip!
I"ve studied the Inglenook Sidings Puzzle extensively and have written a web browser program that generates a random start and then calculates a solution. If you number all eight cars and specify all of their their final positions (which was not the original version) then graph theory can be used to find a shortest solution for all possible starts. Even the shortest number of moves for a solution can be as large as 20 but typically is in the range of 15 to 18. The seven car version, which has 4 cars on the main siding, 2 cars plus loco on the lead, and 3 cars on the other two sidings, actually has longer solutions on average than the eight car version. Thanks for your interest in this puzzle and sharing how you fit it into your layout. Cheers from Wisconsin!
Thanks for watching Andrew. I always look forward to your comments. The Inglenook puzzle is definitely very beguiling.
I've been looking for a program that calculates the solution to an Inglenook puzzle. Can I get a copy of your code?
@@solimar1554 The latest version is an html file with embedded JavaScript that can be opened in a browser. I can send a copy to you via email.
@@andrewpalm2103 My responses seem to go away. you can send to pkol at amer online. Maybe this will work. I have been searching for algorithms to port to .net programming for a while now. Thanks, in advance.
@@solimar1554 Yes, if you put an email address in a comment it is dropped. I just sent an email to what I believe is your address. If you don't get it, let me know.
I need to start registering my cars so I can plan a few operations...cheers
You won't regret it. I find that having planned operations really helps keep me engaged. Thanks for watching!
Nice. What couplers do you use? What did you use for ground cover?
I try to use Kadee #5s (or the equivalent whisker coupler whose number I can't remember). The ground cover starts with a layer of filtered real dirt, upon which I spread some fine ground foam of brown/green. Then I will either hand plant some static grass clumps or break out the applicator for larger areas.
Thanks for posting this interesting video.
After watching numerous switching videos, and indulging in a bit of model switching myself, i have one question. Is it really so necessary to first isolate all of the "stays" one one siding before beginning to sort the "pulls?"
Or can all cars be worked as it's convenient to sort them?
No, it certainly isn't necessary. I just find that it makes it easier.
If the cards show the cars that will be placed in each of the 5 positions, what is the rest of the text info below the picture on each of the cards used for?
The text shows to which industries the car may be sent, decided by the roll of a d6. I talk about it in this video: ua-cam.com/video/7P5zJunCozk/v-deo.html
Would love to hear, why the Montauk.
Not to worry about brain fart. We all have them , then throw in Murphy and his derailment plan and you have an op session. No?
It's a long story... basically there's a picture in John Armstrong's book showing car float ops at a pocket yard somewhere in New York. That picture always fascinated me. Flash forward many years and I learned it was an Erie RR yard at 149th St. on the Harlem River. I put that in a blender along with all my other wants, needs and limitations and came up with the LIRR, Montauk Branch. I still want a boxcab engine, though.
@@longislandrailroadmontaukb982 your right, convoluted story. I thought I was the only one who did things like that. My story is just as bad. My RR years ago was the Oak Valley &Western. I had a parallel track running about half the length. A friend shows up with Proto 2000 's first engine. A TP&W GP18. Non of us knew what that stood for but since my RR went behind the 1/2 bath I named it the Toilet Paper &Water. I have since found out that it stood for Toledo Peoria &Western. I've since rebuilt the RR and now I model the TP&W WITH THE OV&W running along side. The catch ,my story and I'm sticking to it, the to RR have merged and I'm modeling the part of the RR that was never built. Logansport Ind. To Toledo Ohio. At least none can tell me I'm doing it wrong🥴🥴
@@longislandrailroadmontaukb982Would that be John Armstrong’s Track Planning for Realistic Operations?
@@amandahammond2691 Yes, it would. Best single-volume book on model railroading ever.
Looks like the children (cars) like to misbehave when the cameras are rolling...! T'was always thus...!
It's uncanny, really. Thanks for watching!
