  1. (Prof tries very hard to stop slamming his head against a wall)
  2. Dear Mars, At a mechanical level, yes. Knuckle couplers (and their associated height/design/mounting specs) have been standardised since 1893, well-predating the F-unit you're using as your "early time marker". https://en.wikipedia.org/wiki/Railway_coupling#Automatic_Couplers https://www.railwayage.com/mechanical/freight-cars/mechanical-couplers/ Westinghouse airbrakes have been mandated in the same law circa 1893 referenced above, which means that at a basic level "train brakes" (and the associated locomotive controls for said braking sys
  3. ...But AMJ, The color-wires shown on the OP's "9 pin JST" pic in-and-of-themselves don't follow DCC convention, which makes me leery that they are a "DCC decoder 9-pin JST compatible" loom... ...that the pics show the looms completely-removed from the loco (woth no obvious evidence of previously-soldered/unsweated wire ends), further shakes any confidence I might have had that the color coding can be trusted... ...The 4-wire loom arguably is the most "DCC logical", as the Black/Red (Track IN) and Orange/Grey (Motor Out) colors do make some se
  4. Dear Mar, OK, first up, we need to clarify a starting position. Those shown in your pics (thankyou! :-) ) are certainly "plugs", but they are not "DCC Plugs". They do not match any known DCC-spec decoder connector. Now, that said, a quick Google gave this reference to the very-similar Atlas dual-motor GP9. While I'm not sure I'd advocate going "straight to series connection" without doing a lot of proper research first, the thread does give some important clues to the internal wire-color-coding (which, it must be noted, does NOT obey accepted NMRA DCC Internal w
  5. Dear RMWebbers, I'm in the process of building my next exhibition layout, which is fundamentally reliant on Asym Braking with Lok Select (US outline) and an occasional V4 decoder. ( I standardised on Selects, but found myself a couple-short, and the V4s were going-cheap right when I needed them...) Literally using "common as mud" 1N4001 sillicon diodes, (No zeners, "High Spec", "Fast recover", or other excess $$$ options diodes here...) in 5-diode packs (4-in-series + 1-bypass config), with a bog-stock NCE Powercab FW1.65b + MiniPanel acting as a pseudo-"
  6. Dear RMWebbers, O/T, but in Australia, the snakes take their chances crossing the road as much as any other animal... Happy Modelling, Aim to Improve, Prof Klyzlr
  7. Dear RMwebbers, Liam, OK, you asked, I'll "lead with my chin"... - S scale = don't bother. Not enough actually-available US outline equipment choice to give free-reign to your desired modelling inspiration... (IE if you start with a given prototype inspiration that you really want to model, then you'll find the available range in S sadly lacking in range, and you will have to compromise the vision that you started-with... ...and that's a near-guaranteed recipe for disillusionment and stalling-out...) "S-Helper Service" used-to-be your "go to" option
  8. Dear Keith, One of the things about ATSF is that they did document and standardise a lot of stuff. It may be more "Texas-centric", but IIRC Dave Barrow (Cat Mountain and Santa Fe, et al) did writeup some early articles which did a good "101 primer" job of explaining the common/typical western-plains-region ATSF station trackage layout, what spurs and industries went where, etc etc. To look at these "typical" track arrays, they look quite simple, (it's rare to find a switchback, esp in "wide open space" states like Texas and Kansas, where land is plentiful, cheaply
  9. Dear Keith, Unfortunately not, B3:AM suffered a crushing injury (literally) in my last house move approx 5 years ago. (Ain't it ironic, it's own leg-system, which was acting as a load-spreader accross the top of the exoskeleton slipped out of position whilst the layout was in a mid-house-move storage locker, and thus spread precisely zero load when an 8' tower of 55-litre "train crates" tipped-over and fell down directly on the layout... ...guess I now know, when someone asks "...but seriously, how much force can a foamcore proscenium module really sustain without damage?..
  10. Dear RMWebbers, Having had at least one swing at a "night scene" exhibition layout, (and getting the itch to do another, truth be told ;-) ), I have to say I love Andy's adaption/implementation/exploitation of "in-situ light sources" like the car-parked-trackside... ...I imagine many onloookers, even "non-train" viewers, instantly "get" the visual of a large train being illuminated "as it move thru/past the beam of the headlights"... Happy Modelling, Aim to Improve, Prof Klyzlr
  11. Dear RMWebbers, Gotta plead the "Iain Rice" defense on this one... "...A spur which holds 2 1/2 cars is no better than one which holds 2 cars clear, and considerably less-useful than a spur which holds 3 cars at a pinch..." Recast and looked-at from the car-length perspective, as opposed to the spur length perspective, "...a car which is 1.x times the "standard 'nook car/unit length" for a given layout is no smaller than an exactly 2x-standard-'nook-unit-length car, (and must be treated as such, at least mathematically, even if the ar
  12. Dear RMWebbers, Ah, that's be first-production-run with the MRC sound decoder (Ugh!),... thankfully Ath wised-up and later releases were factory equipped with SoundTraxx sound decoders, and are made even better with the addition of ScaleSoundSystems drop-in speakers... https://www.scalesoundsystems.com/product-page/athearn-genesis-mp15 As for the "lights out of position", Ath had a bee in it' bonnet about using 12V bolbs which were obviously too-small for the headlight castings for some time. Why? Dunno... ...but as they tended to die relativ
  13. Dear RMwebbers, I'd suggest a well designed 4x2 in N, (or even HOn30) can certainly hold build, scenic, and operational interest. For consideration: Broughton Vale Tramway (HOn30, but easily converted to N) http://members.optushome.com.au/jdennis/broughton/frameset.html Cripple Creek Central (the MR project layout which inspired BVT above) NOTE! While it's a "roundy roundy", the operational schematic shown illustrates how to conceptually operate it as a "interchange to End-of-Track" shortline... reccomend checking out Kalmbach's "A HO Layout you can Build",
  14. Dear RMWebbers, 2 thoughts: 1 - There's a suspicious-looking loco there, vaguely TP56-ish? 2 - I have to say, it's only that it's the layout builder describing the layout that makes me in-any-way capable of overlooking the use of the term "novelty layout"... Happy Modelling, Aim to Improve, Prof Klyzlr PS sidenote, anyone checked the Tractive Power website lately? The oh-soo-modelgenic TP56/70 looks to have been joined by some bigger brothers,... (The TP90, a SW1500 for the new generation?)
  15. Dear RMWebbers and "Practise Plankers", If you can't readily access the MR issue in question, you can get a sneak-peak of the first 2-pages (inc trackplan, in case it's needed) from here http://www.qgdigitalpublishing.com/publication/?i=664029&p=6 (don't freak out if it loads with a "End of Preview" banner-bar accross the page, just click the "X" to the LEFT of th text "End of Preview", and keep rolling... ...for the astute, the icon at top right is interesting too....) If I catch a hardcopy at my local newsagent, I'll be sure to pick one up for
