I am very tempted to do a little research to see what would be the costs involved in setting up and producing some, but first a little market research! The wires are comparatively easy to set up but are oversize in terms of scale accuracy and are not PPR prototype.
Cheers Jim. Just be very careful and conscientious about catenary installation into tunnels or inaccessible places on your layout.
