Looks cool.
I was investigating your automatic switching track setup, and have a question.
In the picture where "B" is in the common section, and "A" in the inner track,
the bottom switch would be "straight", because "B" set it as it passed. This
means only the inner track would be live, however when "A" switches the upper
switch to the outer track, both would be live, and "A" would continue. It'd be
a race to see whether "B" reaches the second sensor before "A" reaches the top
switch.
I think the bottom sensor only needs to set the top switch (to inner track),
but the top sensor would need to switch *both* to the outer track for this to
work.

| (...) Thanks for your comment Ross. I actually built the setup that I show on my site in order to test if everything works alright... and it does. Wessel (24 years ago, 19-Jan-01, to lugnet.trains)
