Still Rethinking My Inglenook
Below is the current status:
When I lowered the deck height to 25 mm, there was no longer clearance to mount a Digitrax DS52 switch decoder underneath the baseboard, so it's been brought up top and will be covered up with a structure. I decided to keep the diagonal track and the dummny crossing. This track is wired as a Digitrax programming track. The next task is wiring up the Unitrack switches to the DS52 and then finishing tracklaying.Sunday, November 10, 2024

Back To My Inglenook Test Bed
I posted briefly about this on the Micro Diorama Modules Facrbook group. Apparently the idea of connecting a micro diorama module to an Inglenook via a Unijoiner interface was something they couldn't handle -- they deleted the post and gave me a Facebook warning. I decided this was too close to a dysfunctional HOA and left the group -- I'm sure they were happy to see me go.

Programming An Atlas Gold N SP SD9E
This is acceptable given the model's price, which would be considerably higfher if, like Broadway Limited or Scale Trains, it had road-specific details. In this, it's comparable to the old HO Athearn bluebox SD9, which despite its wide hood continues to be an acceptable layout-quality model.
ESU and Atlas provide the loco with certain CVs preset that diverge from other manufacturers. In particular, the engine startup-shutdown is F8, unlike the F9 other manufacturers use. F9, on the other hand, is "drive hold", a feature unique to ESU. If you press F9 by mistake expecting to startup the sound, this can leave the loco stuck in not moving until you think to press F9 again, which is confusing.
ESU also sets default values to CV3 and CV4, acceleration and deceleration, unlike other suppliers. This can make MUing other manufacturers' locos difficult, and as a longtime DC user bvefore I went to DCC, I like the feel of immediate throttle response. I set CV3 and CV4 to 0.
ESU has another unique feature, prime mover delay, which delays acceleration while the diesel engine sound spools up. Again, this makes it difficult to MU an ESU equipped loco with one from other DCC suppliers, and I find the delay in throttle reponse annoying. To get rid of this, I set CV 124 to 16.
Finally, I tested the horn using F2. It is factory set for a single-tone blat. Atlas doesn't provide documentation for other options, but browsing the web, I found that if you e-mail support, they can send you a list of their CVs for the SD7/9 model. I did this and got a list within an hour or so. From their documentatoin:
CV163=0 Leslie A-125SP used Nathan P3s, so I set CV163=11. This worked fine, and the P3 sound is great. Unfortunately, the "generic" horn detail on the body is maybe a Wabco E-2 "blat" horn. There used to be SP style aftermarket N details available, but I think they're much harder to find these days.
CV163=1 Leslie A-200
CV163=2 Leslie S-2M
CV163=3 Leslie S-3K
CV163=4 Leslie S-3L
CV163=5 Leslie S-5T
CV163=6 Nathan M3RT1
CV163=7 Nathan M3H
CV163=8 Nathan M5
CV163=9 Nathan P5 (Old Cast)
CV163=10 Nathan P5R24
CV163=11 Nathan P3
CV163=12 Nathan P3-R4
CV163=13 Nathan P5A
CV163=14 Wabco E-2

Back To My Low-Relief Pabco Paper Building
Then a few weeks ago, I discovered Kato mini diorama modules and the related and compatible pocket size modules, and after a little cogitation, I decided to turn the deconsctructed buildings into individual double-width pocket size modules, which are compatible with Kato mini diorama modules.
What I like about this approach, in addition to the reduced size, which seems closer to N scale, is that the length of the scene is adjustable, and the whole layout configuration that it goes with is also completely adjustable. The single track on the modules can be either a main line or a siding.Also, one issue on which I had been stumped was how to incorporate the water tower that's between the two buildings on the prototype:
I didn't think a water tower cut in half was going to work as a background flat. But now I realized that I can simply build a 4-7/8" wide pocket size module that's deeper than usual and then just mount the wster tower on it and hook it up between the other buildings or not as I please.Monday, September 23, 2024
A Few Mini Diorama Modules
Here is a Klawndyke strtaight module modified to incorporate a 2-position terminal block.
The straight module in the photos below is this terminal module with scenery added. Below is a curved module with scenery to represent an oil field. It uses inexpensive 3D printed details from eBay. A commenter to last week's post said that modules that have scenery but leave the module base visible create a distraction. I did these modules before that comment, and my view is that it's just easier to put the clay all the way down to the base. I sort of like the hidden base better.
