A Turntable For Model Railroads

See the original posting on Hackaday

Way back when, before diesel-electric locomotives were a thing, trains weren’t really able to go backwards too well. Also it’s sometimes necessary to turn carriages around in a small space. For that, the railway turntable was invented. If you want to implement one on a model layout, this project from DIY & Digital Railworld is for you.

The project is at an early stage – thus far, laying out how to set up an Arduino Uno using a potentiometer to control the speed of a stepper motor, which rotates the turntable. The turntable itself is a 3D printed part sourced …read more
