I was working in Seven Sisters shortly before the commissioning of the new signalling, and I realised it would probably be the last time I would be there and considering this is the very room I received my introduction to railway signalling and to what I now call my career, I thought i would take some pictures for posterity and share them with you. www.flickr.com/photos/83079716@N03/sets/72157630668512308/ |

Great set of pics, spent many a shift in there on standby and fault finding. Even managed to 'work the frame' when Cobourg Street was closed during asbestos removal. The frame was only worked in manual when the service was in disarray and the Program Machines were more of a hindrance than a help. Just a pity you missed the front of the Q relay racks especially those containing the track relays as these were, if my memory serves me correctly, unique to the Victoria Line.

Nice photos, but needs an mp3 of the room sounds to go with them to keep the memories fresh.

Glad you liked the pictures. I have also spent many hours in this room as an apprentice shadowing a T.O., just staring at coincidence lights waiting for them to go out. I did take more, including the front of the q relays, they are somewhere on my hard drive, will have look around when I get home from work.

I love the WTT just tucked in behind the wiring.

Fab! What's WP_000125? I recognize the rest of the kit. More please... Changeover switches for the power supplys one position would do the eastbound/southbound feed and the other westbound/northbound feed but some lines dont touch these anymore so they are moved at someones peril. They ave been known to fall about once switched over if left to rot |

Great photos. I hope you and others in such places will be able to take photos and records of all those places as they vanish. The Northern Line and the SSR is a gold mine of old stuff that will go over the next few years.

The Northern Line and the SSR is a gold mine of old stuff that will go over the next few years. Thanks tubeprune! That is exactly my intention, if I can help prevent some of this stuff being forgotten and lost to history, I will do what I can. Unfortunately, as an LUL employee, I don't get access to the Northern but as for the SSR, i've already started... |

Can't claim to know what even 10% of the kit does but very interesting to see behind the scenes of the old Vic Line signalling technology. I agree with Tubeprune - someone from the Museum should really get some high quality photos taken of the old signalling stuff elsewhere on the network - not to decry your excellent efforts in recording this stuff. Thank you  |

The museum has acquired quite a selection of control desks and substation equipment recently, but I don't recall seeing anything IMR related.
Have there been any problems with cable insulation degrading? Cambridge PSB uses relay interlocking for most of its control area (perhaps surprising for a 1983 installation when solid state technology was available), and the wiring has now been deemed unfit to be modified lest the insulation starts dropping off. I suspect that they're holding out to refit the whole place once a decision is made regarding where control of various lines with regular signal boxes is going to go.

There are broad plans (with all the caveats that such plans have) to start converting parts of Acton Depot to be more focussed museum displays rather than just a store, broadly along the lines of "how stuff works" engineering. Naturally this is in part a means of getting some more space built before the place bursts at the seams.
It seems that (having just grabbed this week's newsletter) that they have started by making a signal frame (titled York Road, though I can't immediately say if it came from there etc) work. Not sure what this means in practice, I'll have to do some asking around. I can foresee (though don't quote me on this) that this might lead to wanting to attach the front end to a real back end at some point.
Other plans that have been talked about include e.g replacing some floor panels and seats in preserved cars (particularly the 67 stock) with perspex so that people can see what is crammed in, what it does etc.

Nice photos, but needs an mp3 of the room sounds to go with them to keep the memories fresh. I'll second that. Rooms of that vintage had a particular sound and smell like no other! |

Wow those are thousands of equipments you have! Everything still looks beautiful, but they are already old. Good collection!
