Fast work again - I assume at this rate you'll be finished in time to put it in for the 2010 challenge?

The plan looks interesting, I like the flow and the curviness of everything. The one issue I can think of there is If you're using Kadees, will you have problems with the lack of straight track siting the magnets?

I was going to suggest turning the two sidings in the foreground of the last pic into one to get more siding length, but then I realised that with the headshunt this way does get more length - just side by side. Clever stuff

Having not used Kadees before that may be a problem but Im sure Ill find some straight sections (or small magnets)

It's not just a case of having straight track to fit the magnets, it's more that the couplers need to be dead straight aligned to uncouple reliably - I think you're supposed to have a wagon length of straight either side of the coupler. I only mention it because I've been bitten by this before, although it was with the Bachmann Kadee-clones - maybe the originals are less fussy?

The track I had trouble with was this:

with magnets sited between the facing points, at the start of the short siding, and in the straight side of the loop. I failed to get anything like reliable uncoupling with the 4w Bachmann skips and ended up filing a little off the inside of the knuckle to loosen them up a bit.
