Types

There are several types of track crossing arrangements.

Diamond Crossing

A diamond crossing is formed when two tracks cross each other at less than 90 degree angle.

Square Crossing

A square crossing is formed when two tracks cross each other at a right (90 degree) angle.

Full Flange Bearing

From Progress Rail:

Eliminates wheel contact at the flange way intersection of the diamond. Significantly reduces impact that leads to accelerated maintenance and eventual replacement of the castings and sub-components.

Examples

CIG

Ken Smith built this diamond for the Comanche & Indian Gap Railroad. He used flat bar for all components, with the exception of the short section of steel rail as a transition between the diamond and the aluminum rail. This diamond could be adapted to Full Flange Bearing type.

Here is the material list used for constructing the diamond (either HRS or CRS):

  • 1/2 by 1 inch flat
  • 1/4 by 3/4 inch flat
  • 1/8 by 1 inch flat
  • 2 by 1/8 inch flat
  • 1 by 1 inch angle
