tell, no. 4300 was the only one to retain
this headlight configuration through the
PC and early Amtrak eras.
The door casing contained a twin
sealed-beam headlight, which was simu-
lated by drilling two no. 54 holes into a
small styrene square, affixed to a styrene
tube containing the light-emitting diode
(LED) headlight ❼. The tube was cut at
an 11 degree angle, approximating the
slope of the nose of the locomotive and
serving to keep the headlight beam par-
allel to the ground.
The upper (nose) fixture, which on
the prototype might have been an oscil-
lating signal light, utilized a short sec-
tion of^7 ⁄ 32 " diameter brass tube, cut
slightly longer than the LED it would
contain. I attached the brass tube/LED
assembly to the inner body shell with
CA, being careful to align the axis of the
tube with the headlight opening. With
the LED installed, the rear of the fixture
was sealed for light leaks with black elec-
trical tape.
I like the look of working classification
and marker lights. I installed Detail
Associates JW1708 4^1 ⁄ 2 " clear classifica-
tion lights according to the instructions.
I fashioned LED housings for the lights
from short lengths of^3 ⁄ 16 " styrene tube.
The LEDs, purchased from RadioShack a
few years ago, fit into slots cut about half
way down the styrene tubes. The slots
provide for the LED leads, which were
then bent back, attached to wires ❽, and
insulated with brush-on liquid insulation.
Be sure the slots are cut deep enough
to fully recess the LED from the pro-
truding class light lens. A drop of CA
will affix the LED in the tube, and


another will attach the tube/LED assem-
bly to the body shell interior, placed
directly over the protruding marker light
❾. I wired the class lights in series, opt-
ing to connect them to the reverse light
(yellow) DCC decoder circuit, since they
would act as marker lights when the
locomotive was pushing or running light.
After installing the signal light and
marker/classification lights, I examined
the interior for potential light leaks, and
used black paint and small pieces of elec-
trical tape to seal everything up.
With the body shell placed upside
down for interior access, I cut a piece of
styrene sheet roughly to the shape of the
rounded nose area and placed it directly
on the upper headlight/class light LED
array ❿. With the styrene plate affixed
and sealed for light leaks, the door head-
light LED assembly was cemented to the
inside of the nose door, aligned carefully
to center the headlight. This will func-
tion as the locomotive’s main headlight
and was wired to the white decoder lead.
Once the headlight was sealed for
light leaks, two additional LEDs placed
behind the number box openings were
cemented directly to the styrene plate.
Like the classification lights, they were
wired in series. Both the signal light and
number box lights were wired to the
decoder’s accessory leads.
The eight wires for the lighs were bun-
dled using black thread, forming a single
“cable” that I passed through the center
of the cab. I painted the bundle black to
help hide it. I made a U-shaped fastener
from sheet styrene and cemented it to the
interior roof just behind the cab to hold
the wires in place ⓫.

I removed the front portion of the cab
interior, cutting at a point directly in
front of the base for the engineer and
fireman figures, to allow space for the
lighting. A square notch was cut into the
top center of the rear cab wall to provide
space for the LED wiring to pass.
I sprayed the cab interior a tan color,
so it would be visible through the win-
dows, and hand-painted the engineer
and fireman figures. The unpainted cab
assembly is shown in ⓫.
The front cab interior mount on the
die-cast metal frame interferes with the
LED wiring, so I removed the mount
with a motor tool cut-off wheel. Be care-
ful not to let the metal shavings get into
the gearing of the drive assembly.
There’s sufficient space behind the cab
for a small circuit board holding the
resistors needed for the LEDs. Each of
the four anode leads was connected to a
resistor, then to the blue common wire.
The remaining four cathode leads plus
the blue resistor “common” wire were
directed back to the rear of the locomo-
tive. where I installed the DCC decoder.
With the wiring complete and grills
installed, I carefully reattached the body
shell. All that was left was to add a few
more detail parts (like windshield wip-
ers) and apply some weathering powder.
The result is a fairly authentic-looking
late-1960s E unit.

❾ Fitting it all in. The upper light was
mounted in a^7 ⁄ 32 " diameter brass tube,
which was glued to the inside of the
shell along with the class light tubes.

❿ Mounting plate. Louis cut a styrene
plate to match the curve of the inside of
the locomotive shell so he could mount
the next layer of lights.

number box lights were mounted to the
body shell and styrene plate. A styrene
