INTERESTING AND UNUSUAL MELLORS




PLESSEY (later Siemens) - blue light for bus priority

This is a one off. It is located near Maidstone. This light is a few meters before the main traffic lights (which have now been replaced with boring TSEUs). When the impedance sensor detects a certain amount of impedance the system knows the vehicle is a bus (only double deck buses like the Enviro 400 and B7TLs activate it). When activated the blue light comes on for 3 seconds to tell the bus driver that it has been detected, and the main traffic lights change immediately (normally they will take up to a minute to change).






PLESSEY - wigwag accompaniment

This is located at some fire stations. When the fire engines need to leave in an emergency, a wigwag comes on to stop the cars, when this happens this wigwag accompaniment also come on to tell the firemen that the wigwags are running. This traffic light is rather strange, the middle yellow light comes on for 3 seconds, then the outer blue lights flash alternately.

Traffic Systems Co-operative - boat

Marinas are good places to find unusual traffic lights. These are located at Chatham maritime lock (located each side of the lock to tell boats when to go in). The main part of it is a Traffic Systems Co-operative (as you can tell from the line around the edge), but the light attached to the side is a Plessey.
