KASGRO 340 TON, 12 AXLE, 32’ DEPRESSED CENTER FLAT CAR KIT ASSEMBLY INSTRUCTIONS
Unpacking
1. Remove the bags and parts from the box. Only discard the bubble wrap, as all other material
will be used to secure your completed model for storage and transport.
2. Do not open all of the bags of parts at once in order to minimize the chance any of the small
parts getting lost. The bags are marked alphabetically in the order the parts will be used.
Preparation
1. You will need a clean flat work area 3 to 4 square feet in size.
2. Tools required are a #1 Phillips screw driver, small file, small angled needle nose pliers, hobby
knife, toothpicks, small container to hold water for decals, “setting” solution for decals, and
optionally a magnifier and 400 grit wet/dry sand paper.
3. Spray booth or well ventilated and clean area to paint.
4. Area where parts can be set aside without getting dirty or damaged.
Assembly Notes
1. Please note that many parts in this kit have many small, fine details which are delicate. Hold
parts by the edge as much as possible to minimize the chance that any of those features get
damaged.
2. Use medium viscosity CA glue only. No other glue will hold the parts together. Only a small
amount of glue is necessary. Place a small amount of glue on the part and spread the CA
with a toothpick so all the joint surface is covered. Error on the side of less glue, as you do not
want glue to ooze out the joints.
3. Railfan Models uses and recommends Tru-Color paints, but you can use any brand of paint
you are comfortable with. Tru-Color paint numbers used are: TCP-005 WHITE, TCP-007 PRIMER,
TCP-010 BLACK, TCP-012 CHINESE RED, TCP-017 FLAT, TCP-018 GLOSS, TCP-069 REEFER YELLOW,
and TCP-077 SILVER. While we use custom blends of rust colors, but TCP-405 MATT ORANGE
RUST and TCP-407 MATT BROWN RUST are close to what we use.
4. Please note that the parts in your kit may be a different color or show slightly different features
that the pictures shown in these instructions. The assembly process will remain the same
though.

Wheelsets
1. Remove the wheelsets from the packaging. For the best looking
car, the wheelsets should be painted. Now is the time to paint
as the wheelsets can not be removed from the trucks later like
most other trucks you are used to.
2. We highly recommend washing the wheelsets in soapy water to
remove any residue from the manufacturing process prior to
painting. Thoroughly dry the wheelsets.
3. Paint the wheelsets. While brush painting is acceptable here,
airbrushing works and looks much better. For a newer look, use a rust color with more orange
hue. If you want an older look, use a darker rust color. There is no absolute right or wrong rust
color.
4. Set aside for use shortly.
Span Bolster Assembly
1. Remove the Span Bolsters from Bag A. The 2 halves and steel insert are put together for
shipping, but not glued. Separate the 2 halves and place the steel insert into the slot of the
bolster side with the pins as shown below.
2. Using medium viscosity CA apply a liberal bead along
a flat mating surface of the span bolster without the
steel insert. Use a toothpick if needed to spread the
CA along to entire mating surface. DO NOT GET GLUE IN
THE RECESSED AREAS. This is the ONLY time that you will
use this amount of glue.

3. Place both halves together and apply pressure evenly the length of the span bolster for about
10 seconds. Use a toothpick to smooth out any excess glue along the seam. Set aside to cure
for an hour.
4. Repeat steps 2 and 3 for the second span bolster.
5. After the Span Bolsters have cured, use a small file to smooth out the seams and any excess
glue. The sockets can be cleaned out with a 7/64 drill bit if necessary.
6. This is a good time to pre-thread the mounting holes for the coupler and end trucks. Pull one
each of the black ¼” #4 and #2 screws from bag F. The locations of the screws are shown
below.
7. Start the threading process by turning the screw until it starts to bite into the plastic. At this
point, turn the screw about a 1/8 of a turn then back out about 1/16 of a turn. Rotate the
screw back and forth, advancing the screw about a 1/8 turn each time. Keep advancing
until you feel notable resistance in the case of the truck mounts, and until the coupler screw
reaches the top of the Span Bolster. Note the depth of the fully seated screws below. The rear
truck mounting screw does NOT go in as far as the front screw.

8. Remove the screws and file away any material pushed out of the mounting holes. Place the
screws back into bag F until they are needed later.
9. The Span Bolsters are now ready for paint. Set aside and paint with the Trucks when they are
ready to paint as instructed below.
Truck Pre-Assembly
1. Remove the 6 center sections of the trucks from Bag A. 4 pieces
have round centers and 2 have oval centers. The top of these
pieces (right side of the picture) is the smooth side. The bottom
will have a matte finish (left side).
2. 12 Truck Sideframes should remain in Bag A. Each plastic
Sideframe already has 3 metal springs installed.
3. Dry fit Sideframes to each of the Center pieces to make sure the
Sideframes are perpendicular to the Center pieces. If a
sideframe is not perpendicular, remove it from the center piece,
and use a small file to remove material from below the tab of
the center piece.
4. Once satisfied with the fit of the Sideframes, remove them from the center pieces, and set 6
aside for now.
5. Glue one of the remaining Sideframes to a Center piece. Apply
CA to the back of the Sideframe, and use a toothpick to spread
into the cavity. Press the Sideframe on the Center part and hold
for 8 seconds.
6. Repeat for the remaining 5 pieces.
7. Get the 6 Sideframes that you previously set aside. Move the
glue bottle away from your work! Press the Sideframes onto the
Centers without any CA. You are doing this just to make painting
easier, which is now the next step.

Paint Trucks and Span Bolsters
1. Painting the Trucks and Span Bolsters should be done with an airbrush only.
2. Any shade or sheen of black will work. If you want a new look, use gloss black. Grimy black is
a good choice if you want a faded or heavily used look.
3. For best results and quicker painting, use a quick drying solvent based paint. We use and
recommend Tru-Color paints.
4. A small rod placed through the center of the Trucks and Span Bolsters makes handling easy
when painting. Use tape on the rod to get a snug fit.
5. This is also a great time to remove the Coupler Covers from the cardboard packing and paint
them black as well. After the paint has dried on the coupler covers, paint the tips of the
angled air line silver. Set the Coupler Covers aside in a protected place until needed at the
end of the assembly process.
6. Apply any weathering to the Trucks and Span Bolsters at this time.
7. Once the paint is dry and cured, you are ready to assemble the Trucks to the Span Bolsters.
Final Truck Assembly
1. Loosen the un-glued Sideframes from the Centers, but do not completely remove.
IMPORTANT –You should practice Steps 3 –5 without using glue a time or two before proceeding with
Step 2.
2. Find a small piece of scrap styrene or plastic (cardboard will also work). Deposit a small
amount of CA to the material. You will use a toothpick to apply CA from here in the next
steps.
3. Insert Wheelsets into the axle bearing points on the glued
Sideframe. Move the opposite ends into the loose Sideframe.
You will have to wiggle the Sideframe slightly, but try not to
remove it completelt from the Center piece. (The sideframed in
the picture are for demonstration purposes, your parts will be painted.)
4. Hold the Wheelsets in place with one hand. With your free
hand, use a toothpick to pick up a small amount of CA. Apply
the CA inside the gap between the Sideframe and Center.
5. Press the Sideframe against the Center, making sure the
Wheelsets are seated correctly in both Sideframes as the parts
are pressed together.
6. The first Truck is now complete. Repeat for the remaining 5 Trucks.

Assembling Trucks to Span Bolsters
1. At this time set aside the Center Trucks (the ones with oval centers). These get installed at the
very end of the build.
2. Carefully remove all 4 of the ¼” #2 black screws from Bag F. Leave the other items in the bag
until they are required later.
3. Place one of the End Trucks on the Span Bolster then insert one of the #2 screws though the
truck into the Span Bolster and slowly turn the screw until it catches the threads previously
made.
4. When the screw is seated correctly, the Truck will move about 1/16” to 1/8”between the Span
Bolster and screw head. DO NOT OVER TIGHEN THE SCREWS!
5. Repeat for the 3 remaining Trucks.

Center Body Pre-Assembly
1. Un-wrap the Center Body. The magnets and weights are installed, halves joined and joint
sanded.
2. Remove the 4 smaller pieces from Bag B.
3. Dry fit the end pieces (flat with a small pipe attached) to the corresponding ends where the
pipe matches the sides.
4. Remove the end pieces, apply CA to the end of the body and re-install the end pieces.
5. Dry fit the remaining 2 End Pivots to the bottom ends of the body. Please note these pieces
are not completely symmetrical. One side is flatter. This side goes toward the center of the
body.
6. Remove the End Pivots, apply CA to the joint area on the body, and re-install the End Pivots.
7. While the seam running lengthwise down the middle of the body has already been sanded,
you may want to finish this to your satisfaction before proceeding. HINT: Spraying a little primer
on the seam will make any imperfections more visible. HINT: If you add any filler or primer, wet
sand with 400 grit sandpaper or finer grit. Do not use anything coarser than 400 grit paper.

8. Remove the small parts from Bag C. The
contents will vary depending on the
road number/body style purchased.
340320 will have 4 long Weld Plates only,
while the 340323/5 will also include 4
rectangular Shear Plates. Please note the
picture shown here is of another car series,
and the small bottom weld plates are not
used on this car.
9. Dry fit the parts into the corresponding
opening on the body. They should fit as
shown. In the case a Weld Plate does
not fit correctly, use a small file to
remove material from the bottom or end
opposite the corner with the hole.
10. Remove these parts from body for
painting.
Paint Center Body
1. Because the body is translucent, we highly recommend priming it before painting.Any light
color primer will work.
2. Paint the Body, Shear Plates, and Weld Plates. We recommend Tru-Color Chinese Red, part
number TCP-012, but any darker red color will be fine, especially if you plan to weather the
car. Use the models on our website as reference or other photos online of these cars. Using a
gloss paint will allow the decals to go on easier without having to apply a separate clear gloss
coat.
3. The brackets should be painted as separate pieces. HINT: The bottom of the sheer plates has
the matte finish and the tops are smooth. Place the sheer plates on double sided tape to hold
in place while painting. HINT: Use small tweezers or needle nose to grab the corner opposite
the holes on the flat Weld Plates. This area will be hidden during final assembly, so does not
have to be 100% covered.

4. When the red has dried and cured, it is time to
paint the large white areas. To make this easier
for you, there are two masking tools inside Bag B.
5. Place the masking tools into the sides opposite
each other. Use the picture as a guide to tape
the masks into place. Use a light adhesion tape
designed for masking paint.
6. The tape on the top deck should be placed
where the taper of the deck plating meets the
thin section of plating.
7. On the lower deck portion of the masks, place a pencil mark 3/8 inches from the end of the
mask. The tape on the bottom deck should be placed on the marks of the mask.
8. Paint the exposed area gloss white.
There is a decal placed in this area so
the gloss finish just helps here.
9. Remove the masking shortly after
spraying and is dry to the touch.
Don’t let set overnight though.
10. Mask the other side and paint.
Remove the masking as before.
11. Let the paint cure.
Center Body Final Assembly
1. For 340323/5 only: Apply CA to the inside of the Sheer Plate cavities on the body, then insert
the bottom side of the Sheer Plates into the cavities.
2. The painted Weld Plates can be insert into the appropriate slots on the body without glue. Be
sure the tops of the Weld Plates are parallel to each other.

End Platform Assembly and Painting
1. Remove the contents of Bag D.
2. Dry fit the Sides and Ends to the Platform Cores. The
top of the Side should be flush with the top of the
Core. The joints should be tight without any gaps. If
a gap does exist, use a small file to remove material
from the side of the Core only.
3. Apply CA to one side of the Core. Use a toothpick to
evenly spread the glue over the entire surface.
4. Press the Side on the Core and hold for 8 seconds.
5. Repeat for the End, then for the opposite Side.
6. Remove one of the Lower Brake Pipes from the
cardboard enclosure.
7. Dry fit the Brake Pipe into the opening on the bottom
of the Core. You will need small needle nose or
tweezers to do this.
8. Remove the Brake Pipe, apply CA to the Core, then
press the Brake Pipe into the core with the same tool.
