This is a multimedia kit comprised of 470+ styrene parts on 24 sprues, DS tracks, two small photo etched fret, decals and the set of instructions that need to be reviewed very carefully before gluing any parts together. The DS tracks have no shape or sag. I have tried to introduce this shape by using the Hobby Trax forms. Generally I was successful, but if your model is to be shown in a contest, I suggest that you replace the tracks with individual links (magic tracks or Fruil).
Most Dragon models today are a collection of old sprues and new sprues added to create a new kit variant. In this case, Dragon has done so and you will have some sprues with the same letter but are called out by the color (see Sprues Blue A & L).
