Glossary of Terms

Date:

July 2004

Purpose:

Establish a standardized list of terms used
thr
oughout recommended practices prepared by HO
layout group.

Text:

“Mainline tracks”


Those tracks intended to carry trains from one module to the next
around the layout.


“ Secondary tracks”


Those tracks other than the mainline.



“ Bridge track”


Rem
ovable section of track that is used to join the tracks of one
module to another.


“ Module front”


The module side closest to the viewing public where the main tracks
are located.


“ East end”


This is the right
-
hand end of the module from the front (th
e normal
viewing side).


“ West end “


This is the left
-
hand end of the module as seen from the front (the
normal viewing side).


“ Married set “


Any group of modules in which the individual modules cannot be
used separately for some reason. Married set
s typically consist of modules that carry a
singular theme over more than one module.


“Interface “


This is the end of the module where it connects to another module. An
interface must be uniform to allow secure connections of the module benchwork,
track
s, and electrical wiring.


“Homasote”


compressed paper product.

Module track work

Date:

July 2004

Purpose:

Establish standardized guidelines for track work on
modules to allow compatible connection of
modules.


Mainline


Track considered mainline shall be
Code

100 Atlas Nickel Silver flex track,
nailed to the
roadbed.


Double track mainline


Shall be mounted so that parallel track centers of five (5)
inches and seven (7) inches are maintained for six (6) inches from either module end.
The minimum spacing between the mainline rails shall be two (2) inches.


Cu
tback


Mainline trackage shall be cutback three (3) inches (+/
-

1/16”) from each
end to allow use of six (6) inch Atlas track section for interconnection.


Grades


No elevation shall be allowed in all mainline trackage.


Mainline
curved
trackage


Min
imum curve radius shall be 37 inches for the small
radius and 39 inches for the large radius.


Crossings


Atlas 12 ½ crossings shall not be allowed in the mainline trackage.


Mainline diverging routes


Such as passing sidings and branch lines shall be
a
minimum # 6 turnout or # 8. The following brands will be acceptable: PECO Insulfrog
medium or long radius, Shinohara #6 or # 8, Atlas # 6. A tighter turnout may be used if
the mainline traffic will not use the diverging route. ( i.e. industrial spurs)


B
ranch line


Any additional trackage on a module with the standard two mainline
tracks may be considered a branch line. It can be installed as desired but must be
smooth without any uneven or irregular trackage. If the track is meant to be a mainline
passi
ng siding, it shall meet the mainline requirements.


Uncoupling devices


No uncoupling devices may be installed on any mainline or
passing trackage.
