Turnout control ,uncouplers , signals , yes . In some cases in actually cheaper than using manual . Its wireless using bluetooth. I have already done my proof of concepts and setup a blue network . I am just writing the software to link the panel to node/turnout. Cost is running about $2 - $5 per turnout ,control boards are $7 ,$10 with the bluetooth , $1.50 for 9g servo . Each board can handle 16 turnouts . I also have some US made boards that I am using , more expensive $20 / 6 turn , $ 30 /12turn .So your entire system will be computer based?
For me its purely a cost / flexibility issue. The cheapest I could find Caboose throws was around $2 a pop. I dont really want to crawl under the layout and run a bunch of wires (been there,done that, have several T-shirts) .
Over the years I have used Atlas switches , 1/8 hardboard , and reverse painted plexiglass. The reverse painted plex looks the best.
