Now that there is actually something to see on the home layout, I can let you know that the backdrops are 600m high and there is no way you can see over them or around them when you are following your train so I felt this was pretty important.
Now I am not the sharpest tool in the shed so I wanted something either of the shelf or pretty easy to wire and use. After our last Tuesday nighters and Blog reading I thought the simple two way switch idea (like in your house) with a meter at either end of the block would do the trick.
In the examples shown the train is heading to your right as you look at the screen.
When the train arrives "complete" in the station or loop the driver then flicks the switch on the "block instrument" to show the previous station or loop the line is clear.
