Probably one of the last things you want to do scenery wise on your layout too.
I think it would be the last thing you would want to do scenery wise on a layout. Not in the sense that you wouldn't want to use them, but in the sense that they would be something of a hazard to work around if you install them before the rest of the scenery is done.
Last layout had the poles in the town areas, and they looked good. I tried one small area in another section with wires and they lasted about a week when my grandson plowed through them to fix a derailment. On a "round the wall" shelf layout they might work by keeping them on the far side of the track. But I found my imagination put the wires in with no damage.:mrgreen:
