Just a thought but over the years other than the purpose built V frames was it possible to convert any of the frames that LU already had. I know some places had new rooms built.

Yes of course, Ealing Broadway is an example of a converted N frame, known as N2. North and South Harrow frames and several on the Central were N2 but I don't know if those were newly installed as N2 or converted from existing N frames as Ealing Broadway was. |

I believe Wembley Park frame was similarly modified to work as an IMR to the push button console next door. I have a feeling that as it was on the operating floor rather than in a separate location, it was sometimes the pratice on Sundays to turn off the air and work it as a frame (when the service was much less frenetic than on weekdays).

RT thanks I did a search but noting came up and I know it was mentioned in one of your posts. I take it that the earlier frames were also converted although I can't think of a location at the moment. |

HL I found this I think this was part of the original frame. Wembley ParkDave, Lots of locations had 'part time' frames or remotely worked frames. Wood Green was part time when operated by a signalman. He was present in the service peaks but outside the peaks the frame would be in 'king lever'. IMR frames could be manually worked by a signalman alone if there was no access to the IMR so King's Cross Picc and Ealing Broadway could be worked locally by a signalman after turning off the air. Where a signalman had to work a frame in an IMR then he had to be accompanied by an AET, T1S or T2S as he was not allowed in an IMR alone. Generally the signalman would not work those frames but instead instruct the signal lineman which signals to clear etc i.e. lineman in charge of the room and signalman in charge of train movements. I can still recall signalmen working Wembley Park, the PB console from there was IIRC refurbished and installed as the Aldgate PB console in Farringdon signal cabin, Farringdon signal cabin then worked everything from King's Cross Met to Aldgate, Aldgate East and Tower Hill remotely from its two PB consoles. It is difficult now to recall the many cabins that were worked remotely, the idea was that all would be in the end and after all these years there are still AFAIK some manually worked signal cabins. With modern signalling the IMR per se will not exist, the lever frame having been replaced by ladder logic, PLC and local console, thus the Central Line has only SERs and that will become the norm once all lines are resignalled. |

RT thanks I forgot about the frames that could work by operating the king lever or switch.

I have not looked at this site for a long time as there are some mistakes which have been put there so if anyone copy's the information it shows up. I am sure that there is also some that are okay.

I look in to Mike's site every few months to see how his research into LT Comms is going. Comms of course was my main trade at LT/LU for 17 years. All the info on his website is interesting to me but I really don't have the time to dip into it more frequently. |
