Read these important assembly instructions before starting!

Also make sure you've read the General Instructions first.

Step 1 Cut out the base of the trailer (part number 2) leaving about 5 mm (1/4 inch) margin around the edge of the part.

Step 2 Find a piece of cardboard slightly larger than the part you just cut out. A cereal box will do nicely. The cardboard will stiffen the base of the model and ensure that it is straight. Glue the part from step 1 to the cardboard. When it is dry, cut out around the edge of the part (cutting off the margin you left earlier).

Step 3 Score the main body (part number 1) along its entire length at the eight places indicated by arrows.

Step 4 Cut out the main body.

Step 5 Mark the folds on the main body. All folds are "peak" folds.

Step 6 Apply glue to the back side of flap A. Glue flap A onto the base (part 1) so that it wraps around the bottom of the base (see Figure 1). Make sure that the blue marks on flap A align with the blue marks on part 2, and that the green marks on flap A align with the green marks on part 2. This alignment is very important; if you don't get it right the model will be twisted or bent.

Step 7 Once flap A is dry, apply glue to flap B and glue it to the base (part 1) and align it using the same method as for flap A. To press on the flap you can insert a finger inside the ends of the model and press the bottom gently with your thumbs.

Step 8 Score part 3, the underbody. Score along its entire length at the six places indicated by arrows, and score on the RED LINES at each end of the part.

Step 9 Cut out part 3. Cut along the four short diagonal lines that meet the ends of the red lines.

Step 10 Mark the folds on the underbody. In the order from flap C to flap D, the first and last fold should be "valley" folds and the four others should be "peak" folds. Refer to the blue part of Figure 1 to see what a cross-section should look like. The folds on the red lines should be "valley"; the ends of part 3 fold upwards to form the ends of the body.

Step 11 Apply glue to the back side of flap C. Glue flap C onto the back side of the underbody so that you form the shape shown on the blue part of Figure 1 (seen from the end). The colored part of the underbody should slope inwards at an angle of about 45 degrees.

Step 12 Repeat the last step for flap D.

Step 13 Apply glue to the top of the underbody (the rectangular area on part 3 bounded by the red lines) and glue it to the underside of the main body. The underbody should cover flaps A and B. Make sure the underbody is centered, both lengthwise and crosswise. This operation is the most difficult step in building your model, so go slowly and carefully, and use a finger or other tool to reach inside the model to apply pressure while the glue sets.

Step 14 Fold the ends of the underbody upwards into the body until they are vertical. Flaps E (six of them) should be glued to the inside of the body as shown in Figure 2 below. Make sure the end walls remain vertical while you glue flaps E.

This completes the assembly of the TGV Duplex bar trailer. When you put together your trainset, make sure the bar trailer is oriented correctly. The end of the bar trailer with the windows should be adjacent to the second class trailers (the ones with the aqua blue doors).
