A few weeks ago I purchased a DJI gimbal camera and have been placing it on various locomotives for some really unique perspectives on the layout.
The camera uses a live feed so I can watch where the train is at in real time. One day while I was doing so I thought about adding some kind of a cab control system to enhance it.
All together this makes an entire playable train simulator I can use on my layout. The first ops session was to collect some cars and deliver them to Hersheys Canada.
