Yep, and the "scale modelers" among us would lay out curves that way in the
first place... simply because we strive for as much accuracy in our track as we
do in our models. So... "full-length" models (WITH body-mounted couplers) are
indeed a feasible thing... even in S! Thanks for bringing that point out, Dick.

Hi,
And another thing to remember ...
Very, very large radiuses for the passenger trains to run on!
70' - 80' passenger cars will only run well, barely, on my 42" outside
mainline.

=======================================
All --
I have operated full-length passenger cars with body-mounted couplers
successfully on 33" staging-yard curves. The key to doing this is to use spiral
easements between your straight and curved tracks. A spiral easement is just a
variable-radius curve whose radius changes from infinity to the target curve
radius (i.e., 33"). I have previously described how to do this on this e-list.
Math is not required. Just lay out your curve with about a half-inch offset
from the straight track alignment and spike each end of a .125 (or larger) rail
to the straight and the the curve respectively. Draw a pencil line along the
rail base and you have it.
