I know Bloodnok did some catenary for tunnels awhile ago, have a look on his KUID 60850, and the other chap I know did some wires and pylons, a few years ago, was melee on KUID 74704, I think Kimmy used these for his two bridges v2 UK route. What about snowsignal on KUID 67906, you might as well have a look to see if he did anything as well whilst you're searching, I'm sure he created something that was electrifying......:hehe:
