The North River is in a 12' x 38' room with the corners
rounded to a 22" radius. Track work is essentially flat but there is
a single 2-1/2 degree drop of about 1 inch for scenic effects at Bobston.
It is the scenery that goes up and down, not the tracks.
Scenery is a modified
Hard-shell using a paper papier-mâché layer using Hydrocal and paper
toweling. A second "texture layer is added using Hydrocal and
sawdust for horizontal flat areas. Vermiculite is used for vertical cliff
areas to allow carving. The mica flecks add detail that can not be
duplicated any other way. Dry color paint is used both in the texture
coat and painted on afterwards to prevent any white from showing through.
Woodland scenics Ground foam, shrub and gravel materials finish the
ground.
A 1/2" drainage ditch
along the side of tracks, especially in cuts, adds to the realism of the
track-work. Rail is mostly hand-laid code 83 nickel silver rail with a
minimum radius of 22".
