MOTIVATION
Inspired by narrow gauge logging, mining, quarry
applications
 Provide motive power for a narrow gauge branch
line to existing standard gauge layout
 Build models that aren’t available off the shelf
 Personalize for your railroad
 Make reliability and maintainability important
features – choose smooth running mechanisms,
design them to easily be easily taken apart for
maintenance


SCALES AND GAUGES





HOn30 – HO scale (1/87) narrow gauge with a
“scaled” 30 inch track gauge
N-gauge track is approximately 30 inches in full
scale when using an HO scale factor – 87:1
On30 – O scale (1/48) narrow gauge with a
“scaled” 30 inch track gauge
HO-gauge track is approximately 30 inches in full
scale when using an O-scale factor – 48:1
It’s great fun to dream up narrow gauge locomotive
concepts in HO scale using N-scale locomotive
drive mechanisms, or in O scale using HO-scale
mechanisms – That’s what this clinic is all about!

HON30 CRITTERS I’VE BUILT


Need locomotive designs for narrow gauge applications – industrial, quarry,
mining, and logging, for example.
Five designs developed:
 0-4-0 Plymouth Diesel Critter
 0-6-0 Caterpillar Diesel Critter
 0-6-0 Plymouth Twin Diesel Critters
 British “Hybrid” Diesel Critter
 “Down & Dirty” Diesel Critter
 4-axle Center Cab “Big” Critter

DIESEL “CRITTER” 0-4-0 LOCOMOTIVE
Uses an N-Scale Bachmann 0-4-0 Docksider
Steam Locomotive Mechanism
 Chassis/Frame built using Styrene Strip
 Added a Funero & Camerlengo Plymouth
Switcher “Flat Car Load” kit for superstructure
and miscellaneous parts
 My first attempt at kit-bashing a locomotive,
but not the best-running locomotive !

Bachmann N-scale
“Docksider” Chassis
F&C dummy Plymouth
switcher kit
Styrene strip
Microtrains N-scale
couplers
F&C frame trimmed, styrene strip added to allow tight fit of
Bachmann chassis into frame. New end beam assemblies made
from styrene strip with coupler pockets to hold MT couplers.

HON30 CRITTER – CHASSIS DETAILS
Note – pistons, drive rods and side
rods were removed from Bachmann
Chassis, and lead weight added to
nose of F&C cab.

Details added from
“scrap box” – headlight, muffler,
air tank, tool box, etc.
Final locomotive can be
disassembled easily for
maintenance and repair
10
DIESEL CRITTER LESSONS LEARNED….
Don’t use a Bachmann N-scale 0-4-0
mechanism! This mechanism runs well at two
speeds: zero and fast – not a good switch
engine!
 Find a mechanism that has smooth, slowrunning characteristics
 Make sure the locomotive is adequately
weighted

11
HON30 0-6-0 DIESEL SWITCHER

Chassis Starting Point – Lifelike 0-6-0T N scale
Locomotive – much better running mechanism!
Used an N-Scale Life
Like 0-6-0T mechanism
and build a styrene
frame around it. Side
rods retained per some
prototype “critters”


Funero & Camerlengo “Caterpillar” Diesel Flat Car
Load used for cab/hood, end beams and end
steps, etc.
See article in Railroad Model Craftsman, March
2011, for details

LOCOMOTIVE, CONT’D.
Decorated as a “could-have-been”
modernized power unit for the

TWIN PLYMOUTHS




Inspired to build a twin Plymouth locomotive set for
“could-have-been” replacement of Forneys on a
Maine 2-ft. railroad (for the Great Lakes HOn30
modular Layout)
Bachmann MDT Plymouth N-Scale mechanism has
good running properties, compact, would be a good
replacement for the Bachmann 0-4-0 mechanism
Funero & Camerlengo Plymouth “flat car load”
shells chosen as basis for bodies
See article in Railroad Model Craftsman, February
2014, for details

Body cab cut away
to clear motor
Cab extension built
from sheet styrene
to cover motor

THE COMPLETED “BRITISH HYBRID”

A “DOWN & DIRTY” CRITTER




A partially built body, somewhat warped and distorted,
that originally came as a kit by Mocalova Model Works,
no longer in business, and given to me as a “gift”???
(Okay, smarty, let’s see if you can do anything with this!”)
I discovered that it fits on a Bachmann MDT Plymouth
0-6-0 N scale mechanism!
Became a “guinea pig” for practicing “old, beat-up look”
weathering!
Had to remove existing end beams and fabricate new
ones from strip styrene, unwarp the poorly assembled
body.
27
0-6-0 “DOWN & DIRTY” CRITTER
• Added new exhaust stack from styrene tubing
• Added hand rails made from Phosphor-Bronze wire
• Added cab steps from scrap ladder stock, new end beams from
styrene, and cab horn from scrap box
• Weathered look applied using thinned washes and dry-brushing
28
A “BIG” LITTLE CRITTER
Decided to try a 4-axle HOn30 locomotive
center-cab diesel
 Mechanism: Atlas GP-9 N-scale chassis
 Body: Two F&C Caterpillar switcher shells
 Scratch-built styrene frame

29

Critter conversion kit
 Added features – hand rails, radiators, exhaust
pipes, headlights, horns, bell, engineer &
conductor, tool boxes, re-railers, coils of rope,


39
ON30 4-AXLE CENTERCAB CONSTRUCTION DETAILS
Remove cab, end beams,
skirts, etc. – build new
deck
Add BVM end
beams, styrene,
I-beam side rails
BVM cab, styrene
radiators & headlight
housings
40
ON30 4-AXLE CENTER CAB FINISHED MODEL

41
BRITISH “HYBRID” ON30 CRITTER
Since Bachmann makes the MDT Plymouth in
both N and HO scale, it stands to reason that
the Railway Modeller article critter for HOn30
could also be made in On30, right?
42
RM ON30 CRITTER CONSTRUCTION DETAILS



Mechanism – Bachmann HO MDT Plymouth Chassis
Body – kit bash using scratch-built cab, frame, end
beams, radiator, etc.
Added features – exhaust pipe & muffler, engineer,
tool box, hand rails, horn, bell, etc.
Disassembly was easier, cab
snaps off, no need to saw it
off as was the case for the
HOn30 conversion.
43
CONSTRUCTION DETAILS, CONT’D.

Drew cab parts on
a sheet of 0.040”
styrene, scaled to
O-scale size. Cut
out windows and
door openings
before cutting
“parts apart.”
Tip: I found it easier to score along the outline of
an opening, but then cut diagonals across the
opening, and then snap out the resulting triangles.
44
CONSTRUCTION DETAILS, CONT’D.
 Added styrene I-beam
strip stock to frame sides
 Framed all window and
door openings with
0.030” strip styrene
 Fabricated new end
beams from styrene strip
and sheet material, added
NBW castings
 Note that cab has inner and outer side walls that simulate recessed
doors
45
COMPONENT ASSEMBLY DETAILS
 Cab shell assembled to hood
casting
 End beams and end steps
installed
 Cab side outer walls installed
 New Radiator fabricated from
styrene strip, tubing and sheet
in place
46
COMPONENT DETAILS

shoes
• Added end ladders to frame – styrene strip
• Added new hood panel doors, hinges, latches and louvers from
styrene and wire
• Added door latches, hood railings, rear tool box door and latches
49

A STEAM DUMMY CRITTER



Inspired by old photos of steam dummies, a steam
locomotive in “Horse Trolley Clothes!”
Decided to make one by kit-bashing a Banta Model
Works “Crew Speeder” kit
Uses a Bachmann On30 Davenport Gas-Mechanical
locomotive mechanism

to have them in the open position, corner gussets added at top
to square assembly and provide mounting for removable roof.
54

Original motor cover was replaced with
a simulated boiler/saddle-tank made
from styrene, added steam dome and
smoke stack castings, as well as
smoke box door and back-head
castings.
55
FINAL CONSTRUCTION & ASSEMBLY
 Body shell bolted to
mechanism chassis
with 2-56 screws,
drilled and tapped
 Boiler/Saddle-tank
assembly snaps into
place

ADDITIONAL THOUGHTS




N-gauge and HO-gauge Mechanisms come and go –
need to be flexible in designing a kit-bash around a
given mechanism
Look for mechanisms with smooth, slow-running
behavior
When kit-bashing, “Cut and Try” works best for me –
take one step at a time. If proceeding to the next
step looks daunting, set the project aside and let it
“cook” for a while – ideas will come!
Make the locomotive mechanism easily removable
and replaceable – I usually drill and tap and fasten
things together with miniature machine screws.
59
ADDITIONAL THOUGHTS, CONT’D.
 You don’t have to build an entire narrow gauge
layout. You can build a narrow gauge branch line
to your existing standard gauge layout:




Logging Railway – Logs, Pulpwood, etc.
Quarry tram – Slate, Marble, Gravel, etc.
Ore tram – Gold, Silver, Copper, etc.
Mining tram – Coal, etc.
 On the other hand, if you have an N-scale or HO
scale st’d. gauge layout and are thinking of
changing to something else, try an HOn30 or On30
locomotive or two and a few cars on it to see if
you might like switching to narrow gauge!
