Thank you Evan ;)
Departing Coal Siding, Wodonga. The existing track was supposed to be a temporary one, going back towards Wanganella, allowing trains to circulate. Although it will be almost totally hidden, it is good track, and I decided to leave it in, if I could overcome this problem. I need to construct a special point.
In fact a huge special double track Y junction, with 44 and 46 inch radius curves. I was stumped.
But along came Evan from Indonesia. Exactly one week on, we only have the problem of getting it through the post office :)
Build and test? two days.
Ready to mail in a week.
Very fair price and problem solved!
