Lever colours IMR's & Signal cabins

The blue lever mentioned is 11's in the east IMR, 94's the slot is in the west IMR don't know what 11's is for though sorry.

11 (light blue) Switchlock - now secured normal IIRC.

Also black/white for the Tripcock Tester at Finsbury Park.

Thanks guys for all the replys loads of info to sort out.

From memory 11's is not blue but blue with black rings and as I recall the lever does nothing because it is plated but there are still circuits over one or two contacts as I discovered one morning when frame testing after contact cleaning. I can't recall what the nature of the resulting failure was but it was due to a light contact on 11s lever. 11s may once have been associated with the former single slip layout, in fact the points are still laid out as a single slip on the ground although controlled as 41 & 42 scissors crossovers.

Arnos Grove has a red & black lever which I recall being a route lever.

Yes it probably does but I last worked there several years ago and I can't recall all the 36 levers now! It's one thing working on the railway day in day out but when one covered the whole combine in several disciplines over decades it is amazing how much one forgets once retired. It is true to say that if you don't use it you lose it! One of the joys of this forum is keeping the dying grey cells alive a little longer.



Quite possibly but the layout was rearranged long before I got to maintain signalling in the area. It is of course points 41A and 42A that are physically a single slip layout.

When I last worked the area circa 2003/4 we had the track fuses permanently removed from 'Z' track such that trains could not be routed to 24 road without a lineman, due to rusty rails.

I'm sure the switchlocks at the Picc east end IMRs have red & yellow levers and I really can't now recall the colour of 9s at Boston Manor which was part of 11&12 switchlocks circuitry. I last worked there in 2001.

Could that be because the switchlock works in conjunction with handworked points 1^A/B as you can go either to Olympia or West Ken (depending on the lie of 21 or 22 points)?

Tom yes finally found mention of brown but as Brian said Blue with black rings not on any list so is it something the locking fitter would have done and the colour has just been carried on?
