|" I like track plan. I've been trying to come up with something along the same lines but with a continuous loop to watch the train wind around. Been thinking of hidden reverse loops. With r/c there's no crazy wiring.
Maybe a light spring holding the points to one side. Make the loop automatic. Following with interest. "
I think hidden (or non-hidden) reverse-loops are an exellent idea !
It's possible to gain more height in the given space, whilst still having continuous running.
A closed-loop obviously means 1/2 your track is going UP and 1/2 going DOWN.
You might be able to make a switch with a small-gap, sans moving-points.
The loco would/should follow the 'straight' path on the way into the loop & exit via the curved leg of the switch (wyes could be confusing !!).
Slotcar 'hillclimbs' pretty much all use reversing-loops at top/bottom.
Turning a slotcar on a 'dinner-plate' is not a problem either.
A scheme for the polarity switching, without R.C, is for the slotcars guide-blade to run over a light-action lever-arm micro-switch beneath the slot.
Whilst the slotcar is in the 'loop' the polarity to the rest of the track is swopped.
The guide-blade activated micro-switch operates a simple 'latching-relay'.
With a train, a magnetic reed-switch, I.R. beam, or suchlike easily does the same polarity swop.
R.C boys of course, need not apply !!
The rough-sketches on the previous <<< Page, were VERY quick thumbnails !
The problem for me in 1:35n2, is that I need about 4" of clearance, before the tracks can cross-over.
In 2'x4' I don't think those configurations would work, grades would be crazy !!
They MIGHT just about work in HO On30 or if you have a 'low' mining loco though.
I'm gonna work on 'the looping' a bit more.
My 'top secret method' is to just keep drawing different loops until I see the optimum topology.
