I have 250 - 275 of track on a shelf layout. Runs on a single z1000 with 14ga buss wire and solder joints to track every 3 ft. Have one diesel setup, one steam setup. Both PS3. To run from one to the other, have to bring down one, setup the next. One room just put in Ross switches to keep train in hobby room, while im in there. Good place to park the other for now until I add a new side track at a later time.
Run on the basic DCS infared unit at the moment. I saw the Explorer unit. Only downfall I see is no control over switches. Would have to extend the push button controls lower, and wire to a bigger button to push with a stick. Or the next step with the TIU, AIU, Wifi. Tiu / wifi combo cant find anywhere, along with unknown restock date. But I can get a used tiu on ebay, and all the other components new at an onilne train store.
Dont plan to expand. Just these to 2 setups, run one at a time.
