The signal post came diecast in the white metal alloy zamak. On this was mounted either a red home signal or a yellow distant signal arm. An elaborate design meant that this could be operated by a small handle at the base, which was connected to the arm by a steel wire. Turning the arm could raise or lower the signal.

The post was painted white and the handle was a black plastic.

These came three in a pack.

Later, a two aspect electric signal was produced. Again, diecast and painted white, with a green and red coloured reflector for the lights. These came two in a pack.
