the frogs be very short and dead or polarity switched somehow? Typical
motive power will be 2-8-0s and 2-8-2s or early diesels - RS-3 (Atlas) or
GP7/9 (Proto). Or would KAs in the locos make dead frogs moot?

Sorry. I thought the overhead area was a/the staging area. A â€˜squared
off Câ€™ sounds like a return/reversing loop or maybe/simply part of the
bi-directional mainline. Since operators can always see what is going on
and prevent accidents, the spring switch idea is undoubtedly the
simplest. Set up the spring switches so that a train arriving from either
direction always takes the path to the right. The light spring loaded
switch will let the exiting train pass through when going forwardâ€¦ they
must not back up. Automatic electric controls to flip the switches depend
heavily on the type/brand of switch machine you chose according to your
scale. The Hare device, with its auto-flipping and return path timer, may
not directly activate the type you chose/select. Peruse the G scale
catalogs for options.

Sorry no sketch, and for any confusion. The staging return loop and
staging tracks I think I have in hand - they will need an A/R, detection
and turnout routing controls, but I plan a display panel. The loco
numbers I will know when I stage each ops session.
The area I am concerned about is NOT in the hidden staging area, but out
over the living room along a beam which bisects the area. This is 11 feet
above the floor and not easily accessed physically, but the operators can
see their trains when standing at the top of the stairway.Think of a
simple squared-off C with the ends pointing back to you on the left and
right and the elongated middle four feet away and over an 11 'drop. I
want to make it simple - any train always takes the right side of the
turnout - I think I will lay out two left hand #6s. The problem is that I
cannot have a very thick support structure - a sandwich of 1/2" ply,
1x2, 1/2" ply and foam or cork roadbed (track sound deadening is
desired - suggestions?). so while there is room for wires and I think I
can hide a turnout motor atop the roadbed surface, I would like to
automate the operation so the turnout is correct for entrance and exit.
It may be that the same operator will do the standard gauge runs
consecutively and not have to worry about passing or meeting, but I'd
like to be able to do meets as a complication for the fun of it - say the
freight meets the mail or the motor car coming and going during an ops
session.There will only be room for 3 operators max in the loft. And most
of the time it will be just me and a guest or solo.

So now there are three (not two) interleaved staging tracks in the return
loop? Got a sketch?
How will the operator select and get a train to return from staging?
Will the operator be able to select which track/train returns from the
loop… or do you want first-in = first-out?
If the answer is first-in, first-out … Could a single loop be big eenough
to hold more than 3 trains end to end?
Whatâ€™s to prevent an operator from sending yet another train into
staging when it is already full?
How will an operator remember what loco numbers are in the hidden staging
and be able to address one with DCC and drive it out?

I did consider a spring switch, but worried about changing the polarity
of the frog. The train lengths are indeed short - the primary layout
space is small 10.5 by 11.5 ft and will be narrow gauge. The Standard
gauge comes in and picks up mining and lumber products and delivers some
supplies, so there are only a few cars in each train, I'm figuring loco,
caboose, and 3-4 cars in most trains. Still working out the industries.
And maybe a motor car (DRGW style) and a mail run (Yampa Valley style -
steam loco, rpo, and a coach). The sidings in town will only be able to
hold a car or two. I'm planning a dual gauge wye in the loft space to
allow for turning the SG locos. Staging will only have a reversing loop
and three short through tracks in it as well, and a couple short stubs,
so the siding length should be just about equal to those.
