this is a must have for the rail yard scene. railroad's run on steel rail, but the rail set's on gravel. lot's and lot's of gravel. i have purchased many model power kit's over the year's and i have rarely been let down. this kit did not disappoint. the molding is sharp and clear. there does seem to be a slight bend in one of the support structure's but it is not that bad and i believe can be straightened out with a little warm water and massaging. will add to the rail yard or a material handler and supplier scene.
