Today, being the 50th anniversary of passenger services, seems a good day to make available online the Victoria Line signalling simulator on which I've been working for some time. I've transcribed the entire bookwiring for the Victoria line into a simulator I've written such that every last relay, lever, ATO code generator, Programme Machine and logic function, is faithfully reproduced and runs as per the original. Trains run autonomously under ATO control, and are displayed on scans of the original IMR diagram masters. Frame levers, Programme Machines (with decodes) and most logic functions are also available for display. The Cobourg Street desk is also available, and offers the same control of the IMRs/PMs that the signalling staff would have had. The busiest area to view is Seven Sisters, with its junction to Northumberland Park depot. It's a work in progress and releasing this publicly will probably show up some stability issues I need to fix! Constructive criticism welcome. The simulator also interfaces with the original control room desk and panels acquired from Cobourg Street, which some may have seen at Electric Railway Museum before we closed. The desk and panels will be recommissioned in the near future at Colne Valley Railway in Essex allowing interactive control of the simulator using the original equipment. vicsim.electricrailwaymuseum.co.uk/Happy 50th Anniversary Victoria Line. Kind regards, Paul |

Great work, well done
It does not seem 50 years since the line opened, I remember it well I went for a ride on the afternoon of the first day

There’s a NOOT button on the management console: does that summon Pingu?
I could do with some tooltips to explain each button.

It really should summon Pingu!  It's actually "No Out Of Turn". If the train approaching a junction is not the one the Programme Machine expects, this button is used to instruct the Programme Machine to wait for the expected train, rather than allow this train through first. You're quite correct, however - there's a lot of documentation that needs adding to allow folk to operate the simulator. However, button tooltips ought to be simple enough to add. Currently, I've reached the point where the simulator will run a complete day's service under full Programme Machine control (trains run under ATO, unless they are shunting or are on tracks that only support 120/180 codes). Manual intervention, Push Button and FCFS modes, should all work and are pretty well tested, but the documentation is still in the original handbook and training manuals. |

Why is there a fuss over a reference to a children’s cartoon character?

Why is there a fuss over a reference to a children’s cartoon character? AIUI a 'yellow peril' is some kind of signalling notice. One for Forum Staff to add to the list of common terms. |

I am completely and utterly in awe.
Well, thank you very much!

Very good. Is there any way to reproduce the distinctive noise in the IMR's from the oscillators, relays and 7kc racks?

Difficult thing for me is that I've never been in a functioning IMR (I'm working purely from bookwirings), so I don't actually know the sounds.
The ex-Brixton IMR equipment I've acquired and built into a "mini-IMR" has yet to have any power or air applied, but advice on replicating the sounds in the mean time would be much appreciated! Current work is focused on finishing the soldering of the KGM units on the Cobourg Street diagram.

To get the real experience of soldering on KGM's, you need to be on a small set of steps in a dark curved corridor about one foot wide.

The final video I took last year before we closed the museum - Walthamstow to Highbury using South to North reversing (All trains).
- for those who like such things.
By the end of the summer season we were running Walthamstow to Warren Street reversing. The simulator is now complete, with proper reversals at Seven Sisters 62/63 roads and in Northumberland Park as per WTT32 - just soldering to complete....
Bar debugging, I feel this is a pretty accurate electrical/electronic record of London Underground signalling covering the period from post-pure mechanical up until computers arrived.

Thank you for posting this, I visited at the NRM open day and forgot to take contact details to hear whether this had found a new home. Glad to hear its future is secured. Unfortunately, the website linked in the original post now seems to be broken, is it likely to come back online at some point?

The Electric Railway Museum closed in October 2017 and the exhibits were moved to new homes.

The Electric Railway Museum closed in October 2017 and the exhibits were moved to new homes. I am aware that they are not based at Coventry anymore now in Essex but not yet open as I heard. Hopefully the guy who posted will come along and give an update on the situation. |

There is nothing on the Colne Valley Railway website about the simulator. sweep has not logged into District Dave since early September last year.

Idid the same thing but like you say noting on the website and the original poster has not logged on since September last year, perhaps it's all finished. |

Many apologies for not replying - the simulator had to be decommissioned for a while and other things take priority. It's now back online vicsim.electricrailwaymuseum.co.uk/ (don't forget to Click 'V' in the bottom right and set the timetable to, say 0805, if there are no trains running). Last weekend at Colne Valley Railway we were finally able to put the glass back in the panel, and I had the chance to connect up the finished simulator for the first time. Apart from some lamp issues and some flickering on the Walthamstow Panel, it all seems to work as far as we've soldered (Victoria). (Before we put the glass back in) (Running under the simulator) Still lots of work to do for those who fancy helping with soldering - no signalling experience necessary!  |

It's an incredible piece of work - well done!
Will you include a digital version of the overview diagram for the online sim?

I'd really love to, and it is on my todo list. However, I'll have to draw it myself as I don't have the artwork (or the rights, which I think belong outside of LU). There's more detail in the IMR diagrams than on the panel; the PM (KGM) details are all shown in the Lever Frame views.

Many thanks for the update. Very glad to see the simulator online again, rather interested to have a dig into see how the interlocking works myself!

I know Arcadis hold (held?) the drawings and manufactured the panels, but they had LU drawing numbers and LU had copies. It's probably written into a contract somewhere. |

I promised a better picture of the rebuilt Cobourg Street: We also acquired, from Brixton IMR, the V-Frame, Lever Ops board, Programme machines, Diagrams, Time Coincidence unit, Code/Spot generators, Racks of logic, storage and train/TD coincidence units, if people want to see those. They are for long-term restoration, however.
