90° diamond has been designed using This design was drawn in full scale from prototype drawing and scaled down, following NMRA specifications. This comes in four parts to make one 90° diamond.

It is designed with a 0.015" gap to electrically isolate each corner from the other.

All frogs and diamonds have top of rail heads plated with durable coating that we have tested extensively.

There are two versions available: unpainted and blackened with chemical agent.
