Gradient System

To reach a new level Gradient Bricks are used. The standard rise is 35mm over one standard straight. Level 1 is reached with a single standard straight. Level 2 needs two straights and Level 3 three straights. We found this to be an optimum gradient for a standard straight that produces no stress on the track pieces and provides correct support to the track with no bending or permanent deformation of pieces observed during testing.

Gradient Bricks are identified by notches on one end of the brick. Standard Gradient bricks have a single notch. The rule is to connect to the same number of notches, or one less or one more. So a single notch Standard Gradient can connect horizontally to another single notch gradient brick, a double notch Steep Gradient or a no notch flat brick

When building gradients to reach a level Gradient Bricks cannot be stacked on an ordinary Slot Brick. Because of the slight angle the track is set at, Gradient Bricks are a few millimeters shorter than an ordinary brick, this becomes noticeable over just a short span of bricks. Plain Gradient Bricks are used, the correct Plain Gradient Brick will have a corresponding number of notch marks.

Once familiar with the system it is easy to use. The notches provide visual reference to prevent getting into a muddle with bricks of slightly different lengths, or constructing gradients that are too severe for the track.

We are currently investigating how curves may be used to create steep and compact gradients. We aim to introduce our first curved gradients in 2010.
