This detailed tutorial will kit bash a generic Kato Mikado into a NP W-5
Class coal burning and oil burning Mikado using a GHQ kit. You will
need one GHQ kit for each locomotive. The approximate cost of each kit
from GHQ is $125.
This NP W-5 Class Coal Burner/Oil Burner GHQ Kit will transform a
generic Kato Mikado into a NP W-5 Coal Burner/Oil Burner. I'm going to
kit bash a W-5 NP Mikado because the W-5 Mikado uses a longer tender
which is necessary if you want to install a sound decoder and speaker in
the tender. The tender for the W-3 NP Mikado is a short tender and
doesn't have enough room for a sound decoder and speaker. There is
barely enough room in the tender for a decoder.
You will need a separate GHQ kit to build a NP W-5 Class Oil Burning
Mikado. Most of the photo's in this tutorial will be of the NP W-5 Coal
Burning Mikado. There will be some photo's of the NP W-5 Class oil
burning Mikado as well
There are four bags of detail parts for the NP W-5 Mikado. None of the
parts are labeled and you must read the instructions in the kit very
carefully in order to identify the parts. When this kit is completed,
you will know all the important parts of a steam locomotive. This kit
will take about 30 hours to finish. So, work slowly and carefully.
The locomotive shell, cab and smoke box have been removed. The details
for doing this can be seen in the ESU Lok-Sound Decoder Installation
Tutorial In A Kato Mikado on this website.
Five wires from the decoder will be soldered to the light board. In
this installation the horizontal support bar below the tightening screw
and above the valve gear must be removed on both sides of the locomotive
frame. This is necessary in order to seat the pewter boiler of the NP
W-5 Mikado. You can remove this support ledge with a diamond cutting
instrument in a Dremel and some strong cutting pliers.
You'll need a good pair of cutting pliers to cut wire, remove flash from detail castings and sprue pins.
This is the wiring necessary for a Lok-Sound/Soundtraxx sound decoder
wiring in the locomotive. All the wiring is protected with Kapton tape.
You must cover the entire frame of the Mikado with Kapton tape to
insulate the frame from the Pewter boiler casting which must be seated
on the frame. To see the full installation of a Lok Sound decoder in a
Kato Mikado. I use five wires to connect the locomotive to the decoder.
The support bar was removed from the Fireman's side of the locomotive frame with diamond
cutting tools. This will take some time. Cut the support bar flush with
the frame. Make sure you wear protective glasses when cutting the
support bar. You will have to remove this support from both sides of the
locomotive frame.
The support bar was removed from the Engineers side of the locomotive frame with diamond
cutting tools. This will take some time. Cut the support bar flush with
the frame. Make sure you wear protective glasses when cutting the
support bar. Remove all scrap bits of the support frame with a small vacuum cleaner.
This is an overhead view of Mikado frame showing the complete covering of the frame
with Kapton tape to insulate the frame when the Pewter boiler casting
is seated on the frame. Don't cover the light board with Kapton tape. I
use five wires to connect the decoder to the locomotive; red,
black,orange, gray and white. You could solder the blue wire to the
light board, but it isn't necessary.
The Kapton tape covers the Fireman's side of the Mikado frame to insulate
the frame when the Pewter boiler casting is seated on the frame. You
can see where the support bar was cut flush with the frame.

Kapton tape covering the frame and the support bar after it was cut flush to the
frame.
An overhead view of the pewter boiler casting seated on the Mikado
frame. The decoder wiring is seen at the back end of the casting passing
over the flywheel of the locomotive. Make sure that these wires are
braced with Kapton tape before it exits from the rear of the frame into
the cab area of the Mikado.This is the pewter boiler casting for The NP W-5
Class Coal burning Mikado .

The original front pilot base must be cut to allow the front pilot castings to be glued to the frame of the front pilot. You can see the score marks made with an #11 scalpel blade.
A view of the pewter boiler casting shows the wires coming from the
decoder passing over the flywheel of the locomotive. The wiring must not
come into contact with the flywheel. You can anchor the wires above the
flywheel with some Kapton tape.

locomotive was painted with a Polly Scale Brunswick Green. The decoder
wiring from the cab of the locomotive were also sprayed with Brunswick
Green.

Mikado. Neolube #2 was used to blacken the drivers, valve gear and side
rods.

tender was also painted with Brunswick Green Polly Scale paint. I now
use this paint for all steam locomotives instead of Polly Scale Grimy
Black or Steam Power Black.
An overhead view of the painted NP W-5 coal burning tender. The tender
for the W-3 is a short tender which barely has enough room for a
decoder, much less a sound decoder and speaker. That is why I used the stock Kato Mikado tender.

A closeup overhead view of two PRR L1-s Mikado's (Top two) and the two
NP W-5 Class Mikado's on the bottom. All four locomotives were painted
with Polly Scale Brunswick Green. Each locomotive took about 30 hours to
completely finish. Each of these locomotives weighs at least three
times more than the generic Kato Mikado. On average each locomotive will
pull over 60 cars on level track.
I really enjoyed kit bashing all four of these steam locomotives with the GHQ kits.

NP Mikado #1825 W-5 Class Oil Burning Heavy Mikado kit bashed from a
generic Kato Mikado using a GHQ kit. This locomotive will pull 55 cars
on level Track. The Locomotive with all the pewter castings weighs about three times heavier than the original generic Kato Mikado.
Another view of NP #1837 W-5 Class Coal Burning Heavy Mikado on a siding
east of San Marino. This locomotive will easily pull 55 cars on level
track.

generic Kato Mikado using a GHQ kit.
Track side views of the fireman's side of NP W-5 Class oil burning
Mikado #1825 on the elevated mainline track east of San Marino. There is a Lok-Sound micro decoder and speaker in the
tender. This kit bashed steamer will pull 55 cars on level track.
A NP W-5 Class Coal Burning Mikado #1837 kit bashed from a generic Kato
Mikado using a GHQ full pewter detail kit. There is a Lok Sound micro
decoder and speaker in the tender. This steamer weighs three times what
the original locomotive weighed and pulls over 55 cars on level track.
These GHQ pewter kits are time consuming and a lot of fun to build. If you are interested in steam locomotives, give one a try. You will be pleasantly surprised with the results.
