This N Scale "Skyview" car comes in 2 pieces: the body shell, and the underbody/interior. This car represents the "Creek" series Skytop cars after they were sold to CN. The nose of the car is different, the skirting is removed from the sides, stairwells are visible, the vestibule door window is squared and the solarium's top smallest corner windows have been filled in per CN's modifications to the original car. 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.
