WOW! This is very nice work Steve. It looks like a very large asset and I would assume it to have a length of about 3 baseboards.
But, I'm not familiar with sketchup or its workings, so I don't know what 'slow-down' effect this would have on a relatively small layout. I was anticipating building a route including Redfern / City Circle / North Sydney & Waverton and I had no intention to expand the route any further. So would an asset like this work in T:ANE or would it be better in TS12?
I do like the idea of being able to see activity from the harbour towards Circular Quay, the Bridge, Milsons Point and North Sydney. I had even thought of running a little bit of shipping and maybe a helicopter.
If it's workable let me know and if the bridge is Payware, then I'm happy to contribute.
Enjoy the fights. Cheers,
