1. Cleanup: Turn car over onto the roof, and with a chisel blade knife remove the sprue scrap
from the bottom center of the center bay. Keep the 2 parallel mounting “circles” intact – these
note which way the outlet gates face in a later step.

2. Recognize the A and B ends of the Car: It is now time to understand where the B-end should
be on the model. The B end is where all of the brake appliances will go. Turn the carbody right
side up with the brake line hanging clips facing you (these are the small tabs that run along one
side of the car, underneath the sidesill). The B end of the car will be to the LEFT. The A end
will be to the RIGHT. The only difference between the two ends at this point is the extra hole
to cement plastic parts into on the B end.
3. Fill running board support holes on A and B ends. Due to a molding error, the running
board support holes were molded too low. Clean the hole out with a #76 Drill bit, plug the hole
with .020 styrene rod, glue a small piece of the rod in the hole with styrene cement. Let the rod
stick out of the hole slightly. Once dry, use sprue nippers to cut the excess rod flush with the
end of the car. Use 600 grit paper to clean up. Using a #77 Drill bit, drill new holes directly
above the old holes. (See Photo)

4. Attach slope sheet: Remove the slope sheet pieces from the parts sprue pictured below. Note
that one slope sheet part has 3 holes in it; this is for the model’s B end, or where the brake
appliances will go. Note there is a “recess” where the vertical parts of the end slope sheets sit.
The front part of the channel needs to line up with the slope sheet part you are adding. In other
words, the slope sheet part is not long enough side to side, and the channel part in the car is the
remaining width for the part. Repeat the process at the “A” end with the remaining part.

5. Attach centersill between the three bays: With the car on its roof, cut the four large triangular
centersill pieces from the Underframe part sprue. After cleaning up the gates, cement to the
underside of the car with the raised guides on the inside used as a place to cement to. Make sure
that the “L” part of the bottom of the car faces out. Repeat this process for the same parts
between the other two bays.

6. Attach coupler bolster pieces: Degate and clean up the coupler end bolster pieces from the
Underframe parts sprue (see photo below). After making sure to test fit the parts first, mount
the A end part on the A end; the A end part has NO small holes in it for mounting the brake
appliances. Then, mount the B end part in place. For each of these, the flat bolster sheet needs
to mount flush with the bottom of the sidesill of the body mold. The entire piece should be
parallel to the carbody, with the angled end butting up against the slope of the bay. Cement as
appropriate. The corners of the part should meet up with the bottom of the body sell corner
posts. As the part dries, make sure it remains parallel to the carbody. This is important, so
the end frames (attached later), fit correctly.

7. Attach bolster plates: Degate and clean the two bolster plate parts. These need to be cleaned
especially well on the sides because this signature part is visible above the trucks of the car.
The parts should be mounted so the hole for the truck screw lines up with the hole in the coupler
bolster, from step 7 above. Note the small ridge in the plastic that helps to locate this part on the
car. The long tab “points” toward the sloped bay.

8. Attach the air reservoir assembly to the B end slope sheet: Note that there are two holes for
the air reservoir part to mount into on the slope sheet part added earlier. Also note the hole on
top of the stem over the draft gear for the mounting of the AB Valve. Glue the assembly in
place.

9. Attach the brake cylinder/fulcrum/clevis/horizontal support piece to the coupler
underframe and slope sheet: Degate and clean the brake
cylinder/fulcrum/clevis/horizontal support piece, located on the “Brake Details and Stirrup
Steps“ part sprue. Note that there are two holes underneath the brake cylinder part; these
mount in the two holes on top of the bolster. Note that the lower rod should hang below the
bolster. Also, the long L-shaped piece at top cements to the end sheet now, and touches the
back of the B end upright later (step 11 below).
