Roco/Fleischmann's smartRail is all about taking the good old regular roller stand to the next level. The devise uses Roco’s Z21 technology so the locomotives can be controlled via smartphone, tablet, handheld controller or directly on the device via the function keys. Sensors at the beginning and at the end of the track bed keep the locomotive in the middle of the track bed no matter the speed. Please also visit my blog Sundborg.Wordpress.com (mostly in Danish)
