Much has been posted about more realistic appearance of track,
wheels and "scale" coupler knuckles including their operation,
but nothing has been said about their effects on the more
noticeable close coupling. This is seen everywhere and not
just closeup. With the exception of Accumate Pro, Kadee 711 and
Sargent, none approach prototype head length to the pulling face.
Due to excessive slack in knuckles and draft gear, close
coupling is difficult to achieve.
Measuring methods and results may be found on my site, along
with history, evaluation, mounting solutions and examples with
images. Close coupling is covered in depth. The interaction
among rolling stock lengths, curves and couplers is also
For more details with methods and extensive discussion of
problems and solutions, see first site below in couplers and
Hope this helps.
