The On30 folks have done this ... as a fellow 'newbie' I think this is quite
informative & pretty cool!  Does S/Sn3 have anything like this???

BTW How long do I have to stay a 'newbie'?

On30 For Newbies by Bobber Gibbs

Part Two - Track, Turnouts, Ballast, Curves, Wheels and Couplers

TRACK

Since HO gauge track is close to 30" in 1:48 scale, there are several choices
to consider
for On30 track.  Of course, you could use regular HO track and your equipment
would
operate perfectly, but in On30, the HO ties are too short, too narrow and to
close
together for narrow gauge.  You could lay your own track on On30 ties or use
one of
several commercial brands of On30 flex track.  Some Conspirators install hand
laid or
commercial flex track at the front of a layout where it can be seen and
regular HO track
in tunnels or in hidden sections behind the scenes.  Some even use regular HO
track in
areas where the track looks like it has sunk into the ground, where the
ballast covers the
ties completely or where the ties are covered by asphalt.  A neat touch where
HO track is
sunk into the ground is to have the ends of a few narrow gauge ties sticking
out here and
there to give the illusion that all ties are the same.  In general, ties for
On30 are the
same or slightly smaller than those used for On3.

In 1:48 scale, Code 100 rail equates to about 75 pound rail.  Code 83 equates
to about 55
pound rail and Code 70 represents 35 pound rail.  70 pound rail is adequate
for 11 tons
per axle loading and 35 pound rail will handle nine tons per axle, or an 18
ton 4-wheel
critter.  For fast or heavy mainline trains like the Colorado narrow gauges,
Code 100
would be appropriate and for slower and lighter trains, Code 83 might be used
while tiny
critters and ore cars will look better on Code 70 or smaller.  Lighter
equipment could
operate on heavier rail but heavier equipment would be unsafe on very light
rail.

Tie plates might normally be found only under the heaviest rail for heavy
trains but there
are exceptions to every rule.

TURNOUTS

At this time, only one manufacturer produces On30 turnouts to match its On30
flex track
but you could use any HO turnout and carefully bury the ties, keep only the
ties necessary
to maintain structural integrity and replace the others with On30 ties, or
install HO
switch kits over On30 ties.

I prefer route-selective tournouts so that when I throw for a stub spur, the
spur is
powered and when I throw for the main, the spur is dead.  That's an easy way
to store
unused locomotives without fancy wiring.  Note that when two route-selective
turnouts face
each other and create a runaround track, power must be fed from the single
sides of the
turnouts and insulated gaps must be used on both rails of both tracks between
the
turnouts.

A turnout that incorporates a spring to keep the points tight against the
stock rail is a
benefit when you are moving turnouts around in your experimental phase.
After final
placement is determined, I prefer a manual ground throw or switchstand to an
electric
throw as very few narrow gauge lines would have had powered turnouts and it
looks more
realistic to stop a train to allow a crewman to throw a turnout than to throw
the turnouts
ahead of a moving train.

BALLAST

On standard gauge railroads, crushed stone ballast, with its sharp edges and
points, is
used to keep the ties and rails level and in position and a raised and
properly profiled
right of way provides for drainage.  On a busy and well-maintained industrial
line, the
investment in ballast might be justified by the management but for most
temporary logging
or quarry lines, ballast was seldom used at all.  On my quarry line, where we
produce and
ship ballast, crushed stone is everywhere and only the tops of the rails show
in some
places.

CURVES

The tiniest 0-4-0T Porter ever built was a four tonner with 36" wheelbase
that could
negotiate a 12' radius curve on 12 pound rail.  Our tiny eight ton Porters
will wrap
around a six inch radius curve easily, but may have problems with the
couplers on some
tiny cars.  In my tests, the Bachmann Mogul, with a slight modification, can
operate in
both directions around a 12" (48') radius curve but it looks better on a
wider curve.
The Bachmann Shay will negotiate a 12" curve in a counter-clockwise
direction, but has
problems with tight curves in the clockwise direction due to a restricted
right-turning
ability of the front truck.  Minimum turning radius is supposed to be 15" for
the Shay and
tight curves would be negotiated only at dead slow speed by any locomotive.
Where
possible, incorporate a slight easement into and out of any sharp curve.

WHEELS

On most freight cars on the Colorado narrow gauge roads, the wheels were 26"
while on most
standard gauge freight cars, freight cars were 33" and, later, 36".  Bachmann
On30 wheels
are right on for 26" while HO 33" wheels equate to about 16" in 1:48 and HO
36" wheels
equate to about 18".  Many smaller cars used 16" or smaller wheels.  An HO
shorty flatcar
equates to just over 16' long and the HO archbar trucks look perfect with 16"
wheels.

COUPLERS

You sure can use link and pin couplers if you wish to and IMHO, everyone
should try it.
Once.  That will be enough to convince most Conspirators that knuckle
couplers are the way
to go and besides, they're prototypical on my line and could be on your's.  I
dont use
magnetic coupler ramps and I nip off the "air hoses" and use a tiny
screwdriver between
the knuckle faces to uncouple where ever I choose.  Couplers that are at HO
height (use a
coupler gauge) will work perfectly but you may choose to change the couplers
on your
larger equipment to the common standard of 26" from railtop to coupler
center.  No one is
ever going to convince every Conspirator to use the same standard, but it
makes a lot of
sense to recognize two standards, HO height and/or 26".

=================

Next, we'll create a display/test track and get into some operation.
