Well thanks for the resurgence of interest in this thread...
Neil is right - neither Obituary or progress to report;
Withyn Reach is still in the Shed, although I have been having a good long look at it.
The problem really is one of location; There's room in the shed to set it up (when
Schiller Point is put away!) but the stock is now up the loft. If it was set up in the loft I know I'd operate it more, although for it to work
well up there it needs some modification - moving switches and point controls to the front, as it was designed for rear operation, and the traverser needs a re-think.
I'm not looking to take it out on Exhibition - too heavy and too long to get in the car easily as well - and that's presuming I had the time, and Weekend Passes from SWMBO....
"For" :- I still like it as a layout, and the premise behind it (Exchange Sidings) that means a quick turn-around of rolling stock doesn't look stupid, plus the excuse to run two locos & trains at once. Some bits of the scenery, such as the derelict building are, though I say it myself, some of the best bits of scenery I've ever done. A major "for" point is how long it's taken me to get the scenery to the stage it's at - starting all over again is somewhat daunting!!
"Against" is it's weight, even once it's up the loft, although I recently saw a neat, small three-legged trestle in Ikea which would be ideal - typically it was out of stock

.... I also would like to do a simple US - outline O Gauge Plank up there, for freight.
Schiller Point will never go up the loft; it is much too bulky once set up.
Withyn Reach is far too 'British' (even without the canal boat) to look right with US stock....
My trouble is too many interests and scales, and not enough time.... fortunately I know this affliction is very common amongst Forum members!!!
