I’ve been thinking along similar lines for a while myself, and have some T gauge layout that maybe oneday I’ll be able to get out and finish. I generally try to avoid crashing them, though that does happen if a hair or piece of grit ends up on the track. Part of the train can then move off by itself. Trains can be broken up and reassembled by stopping them over a section break then turning one section off. That allows unlimited length trains, tight curves, steep gradients, etc.

They all simply move in synchronized formation, with the loco not actually pulling anything. Having one universal set of track pieces and just plugging cables into a plug-board keeps things manageable.Įvery vehicle is self-propelled and not coupled to its neighbors. Other custom sections need polarity reversal or other non-standard features. Some projects, especially with roads, do not have any switching at all with the whole track permanently powered for continuous streams of traffic. Other switched sections are only an inch or so long, or have to be very narrow (bridges, turntables, etc). Power sections are typically a dozen or so track pieces in length, so you would need 1 active piece for every 10 or passive – twice as many board types, or all pieces being larger and able to do either job, or build it onto the joiner boards, etc. There are many design tradeoffs at work here, some from the electrical side and some from the model railway design side, coming down in the end to flexibility and cost. Posted in Misc Hacks, News, Toy Hacks Tagged linear motor, model railroad, model raiway Post navigation It’s an option for any time you need to move a few mm scale object in 2D. This feels like it could be used for many things, far beyond model railroads. Modelers in larger scales might well use it for automated pedestrians and such.Īlso an advantage, all cars are powered, so coupler reliability is a reduced issue. Items like autos and boats can be automated as well. Since the system also guides the car, actual ‘track’ is unnecessary, and is using printed paper covering rather than 3D track.

With microstepping, a step of 0.25mm is possible, and trains run smoothly. The underside of the PCB has another coil, so the effective pitch is 2mm. In a recent Hackaday.io writeup, author describes a PCB technology based linear motor system to externally drive T scale locomotives. T always seemed to us a long way out on the bleeding edge. In practice, even more of a problem is getting reliable electrical contact through a metal wheel on metal track (about the worst possible design for a contact). But fitting a reliable mechanical drive mechanism and MCU board in a package this size is a challenge. Recently a new scale, named T, at 1:450 has been pushing this barrier. So many modelers are drawn to the smallest scale they can use. Railroads are large, linear pieces of civil engineering.
