Penn ‘O’ Gaugers is a modular model railroad club
created for those who enjoy building and running ‘O’ gauge model trains
having an interest in preserving some of the rich railroading history
Eastern Pennsylvania area. The club’s model railroad is based roughly
on a 40 -
50 year timeline between the 1930’s to the late 1970’s featuring
not limited too, equipment from the Reading and Pennsylvania railroads.
meets several times a year at various locations to
setup, run and display its modular layout. A modular layout is a layout
can be disassembled and reassembled. The various modules are owned,
maintained by each of the club members. Members are responsible to
module(s) to the display locations, help set up and then are able to
own trains on the layout.
layout is designed to run using the Lionel TMCC
Legacy Command system.

The use of multiple modules in a set allows for greater flexibility of
routing. Intermediate modules can be of any length and width, (within
so long as the overall length of the set is exactly a multiple of 4
Corner Modular, a corner module
fit inside a four foot square, 48” long by 48” wide. See Figure B.
Frames to be constructed of 1x4 lumber. The boards should be
straight, solid and free of excessive knots and should be sanded
exposed edges of the framing material should be rounded (sanded or
edged with a
router) in order to minimize splintering and facilitate comfort during
handling of the module. The frame should be glued and screwed together
strength and it must be square and flat! Yellow carpenter’s glue is
to white glue.
All visible side surfaces,
including the ends of the module, will be painted a satin or semi-gloss
The deck surface should be painted an earth tone brown before applying
or any scenery to protect it from water base diluted scenery adhesives.
Each straight module shall have
four legs, corner module five, that are removable. Legs must have 3“
adjustment bolts (a carriage bolt) to allow for a total of 2” of
movement. (see Figure C) The adjusting bolt and corresponding T-nut
size may be
either 5/16th or
3/8th” diameter. The bolt should be completely threaded
over it’s full length. The exposed portion of the adjusting bolts are
extended so that the top of rail of the two main lines shall be exactly
(forty) inches above the surface of the floor. With the deck and rail
as described above, the leg length is 38”. This length should be
the difference between 3/8” and the actual thickness of the deck
material if other
than the preferred type. Locations for the legs are shown in Figures A
for both straight and corner modules. The legs will fit into pockets in
location, as shown. Experience indicates legs that slide easily in and
the pockets are preferred to a snug fit since dimensional changes in
caused by high humidity could cause the leg to become stuck in the
Recessing a T-nut on the inside center of the leg pocket will enable a
be used to retain the leg in the pocket while the module is being
moved. A #4
screw eye may also be used.
Two sturdy C-clamps, of at least 2
inch opening size, will be used to secure the modules together during
Two clamps shall be provided with each module by owner.
AND BRANCHLINE TRACKS
The two mainline tracks shall be Atlas ‘O’ 21st
Century Track System with traditional plastic simulated wood ties. The
tracks are to be secured (glued, screwed or
nailed) onto standard ‘O’ gauge cork roadbed. The
roadbed should be
glued to the surface of the module in lieu of nailing to help ensure
roadbed remains flat (all-purpose white glue or caulking adhesives are
suggested). The roadbed should be painted grey, similar to the shade of
used for the ballast. Curves are permissible and shall be a minimum of
(36” radius). Corner modules will use O-81 (40.50” radius) for track 1
(36.00” radius) for track 2.
Spacing The double track mainline will have a spacing exactly
4 ½” on center. Track 1 centerline exactly 4” from module front
edge. Within a
module or multiple module set, the track centerline may be different
have curvature as long as the track centerlines at each end of the
set exactly as standard. The mainline track/rail at the end of each
shall be straight, parallel and flush with the front edge of the
degrees from the module end (see Figure A & B) and be screwed down
the last 2 track ties as shown in figure D. Track tie lock should be
help with final track alignment. Rail joiners are not required between
but extra attention shall be given for the close track location
Turnouts on the mainline shall be a minimum of O-72 turnouts
recommended from Atlas or Ross Custom Switches. All turnouts may have
electrical switch throws. Turnouts between the mainline tracks shall
center rail insulated to keep each of the mainlines electrically
The ballast used on the mainlines shall be Woodland Scenics
Gray Blend Coarse Ballast # B1395.
Branchlines shall be Atlas ‘O’ track. Cork roadbed need not be used but
are necessary to change from the elevation of the mainline tracks to
branchlines. Turnouts shall be a minimum of O-54 turnouts but a minimum
is preferred. Any ballast may be used for branchlines. Any
turnout from the mainline tracks shall have the center rail insulated
each of the mainline tracks electrically isolated.
Right hand running shall be the routing convention for
locomotives on the mainline. In looking down the track in the direction
travel, the engine will operate on the right track. The two mainlines
designated as “North to South” and “South to North”. The mainline track
1) on the outside is S to N(northbound) and the track on the mainline
(track 2) is N to S (southbound).
module will provide mainline power busses and connectors in order to
said power on a continuous basis throughout the display. The
layout is designed to be powered from a single location. (see figure E)
power for the club layout comes from the Lionel ZW-L transformer.
This advanced transformer provides the
for operating the club layout with a full 720 watts of power,
all within a single unit. This modular layout is designed to
run primarily as command control but this transformer allows the
capability of running conventional locomotives with the Legacy
without the use of additional TPC’s and such.
POWER BUS CONNECTORS
Each module should have an electrical bus running its length
consisting of six (6) wires of 12 gauge stranded wire. 16 gauge
shall be used for the drops from the track to the bus.
The electrical bus for each module
will be connected to the adjoining module using ‘Anderson Power Pole’
Connector wiring assignments:
1 = Mainline Track 1 Power, Red, ‘A’
2 = Mainline Track 2 Power, Red, ‘D’
3 = Branchline Track Power, Red, ‘B’
4 = Accessory Power, Red, ‘C’
5 = Ground “U” (common for all tracks), Black, ‘U’
6 = Earth Ground, Green
wires shall have their wiring assignment numbers labeled a minimum of
location within each module.
Each main line on the module should be connected to the bus
around the middle of the module.
power shall not be used to power accessories, such as electric switch
lights, or other powered devices.
power is to be used for switch machines, lighting and signals only. Any
(such as motorized accessories) should be powered by a separate power
provided by the individual module owner.
The overall design, motif and
scenic details are optional to each module builder. Each module can be
as a diorama within itself, or it can be planned to merge with other
the layout at the discretion of the module builders.
All grass, ground cover, and foliage will be in appropriate
shades with no bright toy-like colors in appearance. Autumn foliage is
permissible. Trees, tall shrubbery and other such ground cover shall
proper clearances so as not to interfere with any train operation. Any
surface not covered with scenery materials should be painted a muted
Each module will have a removable skyboard that extends 12”
above the full width of the module surface. Care should be exercised to
gaps between adjacent skyboards to a minimum. Each skyboard will be
Masonite with an overall width of about 16”, and will be painted with a
blue paint. Use Sherman Williams #SW1787 Baby Blue or #BM 33-4 Universe
the viewers and a satin or semi-gloss black on the back. The rear edge
will be blended into this neutral sky background as appropriate. If you
carrying handle on the back of the module, you will need to notch the
accordingly. The skyboard will be attached to the back of the module
strong clamps, bolts & washers, or other appropriate means to
firmly in place.
A masonite fascia board may be provided on the front of each
module. The fascia will be the same height as the top of the deck for
three inches from each end of the module. The area in-between these
be of any height (within reason) required to effectively blend into the
landscape of the module. The fascia board should be securely fastened
module using flat head screws which will be covered by the skirting.
viewer’s side of this fascia should be painted a semi-gloss or satin
Skirting is attached to the fronts of the modules at
public displays for “dressiness”. It is held on with VELCRO, thus each
must have a strip (1/2” wide is OK) applied to the front along the top
The hook side must be attached to the module so that the top edge of
meets the bottom of the module deck. The skirting is provided by and is
responsibility of the club.
