This N Scale "Rapids" series Skytop car comes in 3 pieces: the body shell, the underbody/interior, and a sprue with 24 seats. There are provisions for wiring and installing a 2mm LED in the nose, as well as room under the body to install a function controller for the lights. This model is VERY FRAGILE and should be considered a "crafter's" model. You can use any of the Nystrom trucks available here, but I recommend using the 526E trucks to allow you the option to use track power. When assembling the model, slide the underbody piece at an angle into the nose first, then gently seat the pieces together.
