Hopefully those of you with a signalling background will be able to help.
The different types of lever well the colour they are painted have different meanings can anyone provide a full definition please.
Some are obvious like
Red-signal
Black-point
White-spare
Yellow-release
Blue-auto working
It's when it comes to the mixed colours and checking on line there is only mainline answers.

Well it'a a while since I was in signals (pulling levers) but you have missed slots/switchlocks different colours depending which line/route not to be confused with the push pull frames they gave additional locking on points. Someone like Harsig or Railtechnician are the right people to tell you more. |

Someone like Harsig or Railtechnician are the right people to tell you more. It's been a while but red/black striped springs to mind for route levers as used in Arnos Grove IMR on 25 and 36 routes but also as slot levers elsewhere, IIRC blue/black striped for a stick relay circuit (although long plated out and I never saw one anywhere else) in Acton East IMR, red/yellow striped for switchlock point indications in Boston Manor IMR and Oakwood IMR, brown for the level crossing control in Neasden IMR. I believe (I could be wrong but I think I read it somewhere) that green was used for fogger apparatus (automatic detonator placers) long ago. |

I remember 29 lever at Baker Street in the 1970s this was a route locking lever, the push pull frames Finchley Road and Rayners Lane and Harrow now that brings memories back not that I would want to go back. |

As I said 'I could be wrong' and now that you mention it green for TD rings a bell although checking my signal lineman notes on frames there is no mention of green levers although I'm sure I must have that in writing somewhere. Thinking on I have in my head black/white striped levers and I'm wondering where I recall that from, I certainly can't recall seeing any in my days on the job. It is possible that I am confusing LT signalling and BR/other signalling as I possess a number of signalling texts/references in my library, most of which I have not looked at in years. |

Black/White that came to mind was actually for BR cabin levers painted in chevrons, up or down according to direction of road, rather than stripes. I imagine that LT may have been the same for fogger apparatus in the original cabins but I don't know and I've never seen fogger apparatus controlled from miniature lever frames.
