Signal Posts

Here are a selection of the different types of signal post you will find on the NYMR

 Levisham Starter
Levisham Down Starter		 This is a very good example of a NER Lower Quadrant.
It uses a wooden post with the arm in a slot The cast iron spectacle plate is heavy enough to return the arm to the Danger position if the mechanism fails.		 Fixed Distant
Fixed Distant		 This is another good example of an NER Lower Quadrant.
This time it is a Fixed Distant, The arm is permanently fixed.

This is a good example of a standard BR Three aspect colour light signal.
This one is the Platform Two starter at Pickering. To the left of the main signal head is a Positional Light shunting signal.		 Pickering P2 Starter
Platform Two Starter at Pickering		 This is the Positional Light Shunt signal controlling the exit from Carriage and Wagon at Pickering. The yellow shunting signals control yard access to the main line. When the yellow is on Yard shunting past the signal is permitted but it has top be cleared for a train to access the main line, in this case Platform Two at Pickering Shunter
C & W Yard access Shunt Signal at Pickering

Grosmont Outer This is a typical Upper Quadrant Signal.
The signal is the outer home at the bottom of the bank on the approach to Grosmont. It is electrically operated and mounted on a tubular steel post.
The Distant is fixed.		 Grosmont Distant This is an Upper Quadrant Fixed Distant mounted on a tubular steel post.
Note the Green spectacle has been obscured to prevent it showing any green light.

Now try our simple Mechanical Signal Box Simulation . This is a very simple station and uses a 15 Lever mechanically interlocked frame.
