Programming A Walthers Proto SW900 With ESU LokSound
The other feature I'm less enthusiastic about is the "prime mover delay" available on full-featured LokSound decoders (but not the economy LokSound decoders on Walthers Mainline locos). In additioon to normal momentum from CVs 3 and 4, this adds an additional acceleration delay while the sound of the prime mover spools up in the decoder.
Since I've never driven a prototype diesel, I don't know how much this additional throttle delay actually reflects the prototype. The main problem I see from a model perspective is that this makes a loco equipped with an ESU LokSound decoder incompatible for consisting with locos that have decoders from other manufacturers, since the ESU equipped loco won't accelerate as quickly as the others -- and that would even include Walthers Mainline locos with the economy LokSound decoder.
The way to fix this is simply to change CV 124 to 16 to eliminate the prime mover delay. Then the model will accelerate compatibly with other locos.

Cosmetic Job On The Pola N250 Quarry
On the next level up, there is a shed that apparently holds some sort of crushing and grading machinery. This might be sort of credible, so we'll keep it. There is also a cover for some sort of conveyor up to (or down from) the loader itself, maybe halfway credible. At least it's a conveyor
I said in my last post that I would try to use vegetation to distract from less credible features and focus on what looked most like a coal loader. Here's the result:
I filled the bins at the bottom with Woodland Scenics Foliage Clusters, held in with Elmer's Glue. I planted more of the Foliage Clusters around the rest of the base on this side and then planted some JTT trees to focus the view on the credible parts of the coal loader idea. Here are a few pictures that I used for inspiration: It'll serve for now, there's just very little available in N that isn't a much larger facility. If I get inspired to scratch build something better, or if a new, better model comes along, I'll either swap it out on this module or build a new module. That's one advantage of doing things in small steps this way.Sunday, December 8, 2024
The Model Power Blue Coal Depot
This particular quarry model seems to have taken some design features from the larger N245 coal mine model.
This is much more clearly North American, since it was based on a Model Railroader series, “How to build a coal mine”, by Jack Work in the October, November, and December 1959 issues.My aim has been to simplify the N245 kit's profile and do as much as I can to distract from the extraneous features and make it look a bit more like an actual coal loader. Here's the current status:
I'm going to continue covering the extraneous parts with vegetation. The ivy is made up of Elmer's glue brushed onto the model full strength, covered with Woodland Scenics fine turf pressed into the glue.Sunday, December 1, 2024
"Found Item" Module
The industry on the sidinmg is a Pola coal loader kit from the 1960s. I'm not sure if it looks like any coal loader in the real world, but little else that size is available in N, and it was fairly inexpensive on eBay. I plan to bury it partly in a hillside and cover much of it with ivy or kudzu.
The main line at the front can connect with other Pocket Size/Kato Mini Diorama modules at either end, or with the Inglenook at the near end. Scenery is the net step.

The New Atlas N Scale FA-1
One feature is a Next18 DCC socket. This is mounted on a plastic motherboard above the motor toward the rear of the unit, where the Next18 socket points downward. I used a Digitrax DN167n18 decoder.
The best way to get to this is to loosen the rear nut and screw that hold the two halves of the chassis together enough to lift the rear of the plastic motherboard up, remove the Next18 dummy plug, and insert the Next18 decoder. There is barely enough room for trhe decoder to fit between the socket and the chassis, but it does fit.
Once I appllied power to the loco, I noticed there is an extra set of LEDs at the front 9of the chassis. These will allow the number boards to be lit and controlled separately from the headlight. The headlight is controlled via the usual F0:
With a DCC-only Next18 decoder, the number boards can be lit with F1: I don't know what function controls this on a sound-equipped loco.I don;t believe these locos have flywheels, or if they do, there is very little momentum effect. However, setting CV 3 acceleration momentum to 2 and CV 4 deceleration momentum to 2 will mimic a flywheel effect. The loco has a 5-pole skew-wound armature and operates very slowly and smoothly.
Unfortunately, as seems to be the case with recent Atlas N locos, there's no documentation in the box. Users need to figure out shell removal and decoder install for themselves and intuit the headlight-number board functionss. (The shell comes off by spreading the sides outward with small screwdrivers or toothpicks.)
An exploded diagram of the loco showing the location of the Next18 socket would have been very helpful; it isn't immediately clear.

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.
