    Where Are All The O-Scale 2-rail Steam Engines?

    You may have to settle for Brass or see about getting somebody to 3d print you a basic shell to put over an easier to get locomotive. A quick google indicates that there are a few people out there with 3d models of various steam locomotives. You'd likely need to add any rails to it and paint...

    Redo on my Chinese railroad layout

    A bit of a late reply here as I hadn't had anything to say. But, right now, you can get a laser engraver/cutter to attach to several of Creality's 3d printers with minimal need to modify anything. The main physical mods that I've seen involved either installing a switch or disconnecting the...

    Redo on my Chinese railroad layout

    I'm still waiting on a couple parts, but I've got nearly everything I need. The top left to right are the mount for the servo tester and toggle box for the actual switch. It's probably hard to see, but the toggle controls the direction and the DPDT switch controls the actual powering of the...

    Looking for feedback on new N-Scale layout

    Keep in mind that even youngsters do break legs and over time that the ducking under may become an issue. Personally, I'd make it a simple lift out section and wire that into the rest of the track using a simple terminal block. You can still duck under it as your design calls for, but when you...

    My stupid noob questions

    If your budget allows, you'll likely want to upgrade to DCC at some point. It is more complicated and tends to be more expensive, but the trains are much more satisfy to operate and you can work with more than one on the same track without having them having the same speed. They also feel more...

    Considering tearing out my old HO layout.

    TBH, if there's a trainshow or swap meet near you, that's likely going to be the best way. I don't like selling things like this on ebay just because it can be a hassle to get the right packing materials to actually send safely through the mail. If any of it is at all collectable, you can also...

    How many prefer to buy DCC equipped vs. DCC ready?

    That's more or less why I just buy DCC equipped ones where possible. I'm not particularly anal retentive about my locomotives being completely right in the model, so it's less of an issue than it could be. That being said, if I had to have a particular model that isn't DCC, I'd consider doing it...

    Laying Cork Roadbed

    TBH, I'm a bit curious as to why even bother with cork when there's better materials available. I've personally been using foam trackbed from Woodland Scenics, but I suspect there are other options. It's easily bent into the right radius, glues down easily and damps the sound from the tracks a bit.

    Thoughts

    Mostly because our eyes were not intelligently designed. Unlike some species like some frogs where the elements of the eye move to focus, our eyes have to change shape to do so. If we look 20 feet away for 20 seconds every 20 minutes, we can reduce that a bit, but over time the eyes are going to...

    ?? dcc system N scale with Ho scale ??

    Depending upon your comfort and expertise, it might be worth looking at DCC++, it has a bunch of features for working with complex layouts. I can't tell if it will allow you to properly control them both at the same time, but it should allow you to switch back and forth relatively easily and it...

    Sometimes track plans don't work out

    This is definitely true, my layout is pretty much a nightmare in terms of the various curves going on because of how much I needed to do on the module. I just plan on never running any trains very fast through any of it. It's also easy to forget that the curve itself is just effectively just...

    FLAT 3D....Serious Post

    Barring a budget large enough to hire somebody to paint one, probably the next best thing would be to create a 3d model in software and then print that with whatever perspective you're looking for. The more you constrain your viewing angle, the more realistic you're likely to be able to make the...

    FLAT 3D....Serious Post

    It depends what you mean by "work." The more constrained your perspective is on the "layout" the more realistic it's going to look. It's definitely going to look odd when there's a train mixed into the scene, but it's definitely doable to create a layout picture that appears to be 3d from one...

    Redo on my Chinese railroad layout

    I've been rather busy with school, but now that I've graduated, I'm working on this again. I've found what appears to be a great method of controlling the turnouts from below here, https://1fatgmc.com/RailRoad/Servo%20Control/Servo%20Control-Index.html . It looks rather cool and like something...

    Scratchbuilding a turntable

    Yes, this is true, If for some reason you don't want them all evenly spaced, this approach likely wouldn't work. At least not without having unnatural pauses in various places. If you want it to be unevenly spaced or you want to skip over positions, it might make more sense to have a fly wheel...

    Track Laying Tool?

    I've been contemplating just 3d printing a guide to lay tracks. It's overkill if you're not either using flexible track or hand laying, but in those cases, having a guide that has the appropriate groove for the track bed and track would likely save a bunch of time. Otherwise the suggestions...

    Scratchbuilding a turntable

    Rather than messing with those sensors, have you considered just 3d printing a geneva drive? That should allow you to get precise centering at each index point, without having to have the motor stop at precisely the right spot. Something like...

    Electricifying my layout

    It's worth noting, that you can also use a standard computer power supply for this sort of thing. The standard ones will give you from 3.3v to 12v which should work just fine. Depending upon the actual lights you use, you may not even need resistors. Used ones can be had for practically...

    Figuring grade..

    The calculation here isn't particularly difficult, you get roughly 98.96" per 90 degrees of curve. So, over the course of 90 degrees, .9 inches is roughly 1 percent increase in grade. So, if you keep it to no more than 2.5 inches of rise, you'd be within the 2.5% grade window for that portion of...

    Tablet control via Arduino

    I got the gear, came more quickly than I expected. I won't have time to complete the install until this weekend, but getting the Bluetooth module hooked up to my Arduino Uno and that connected to my tablet was pretty easy. At this point, it should just be a matter of connecting the power lead to...
