The Helix
The next step on my layout was to complete the four levels
of the helix. The lowest level is the return loop at the far end
of trackwork, behind Shreveport Union Station. The second
level up shows where the benchwork, to the right, connects
to the lowest level of the helix, leading to the left, with a piece
of one-quarter inch Masonite. Four-and-one-half turns above
this reaches track level on the upper deck, at Siloam Springs,
Arkansas (1).
The helix starts its descent at Siloam Springs in the back dis-
tance curving to the left and around into the foreground.
Fabricated plywood support arches stabilize the plywood
benchwork in the center of the helix (2).
The helix then curves around to the right and ducks beneath
the plywood deck at Siloam Springs (3).
