Wildlife Intrusion

 Postscript

A large wasp nest discovered in one of the lineside cabinets at Broadway by Neil C while he was sorting out some issues with the track circuits on Tuesday.  Make a bit of a mess getting it out!

  1. I bet. What happened to the little creatures ?

  2. Hello Curly, thanks again for the reports and signal post update at Broadway. Is there someplace that I could find out what signals are where on the line please as I want to make a model railway of the line in N gauge. Again great pictures and reports on a part of the line that enables it to run. Without your teams efforts there would be no trains at all!
    Regards
    Paul & Marion

    1. Do you want this info for the whole line? I have the signal layout for Broadway , a total of 17 signals (including ground signals). Perhaps you could let me have your e-mail to make it easier to communicate this.
      I believe our H of D Malcolm W has copies of the signal layouts for the other stations but he is on hol next week so I will get you this info in the fullness of time!
      Regards RAC
      Mail me at Richard.collier_1@btintnernet.com

      PS Do you need signal distances from the signal box?

    2. Thanks Curly, I will send over on Tuesday PM, on our way to my sons for the weekend
      Regards Paul

  3. The wasps may have moved out because they didn;t have the requisite 'STRIPES' to be on the track.
    Regards, Paul.

  4. Ah, that picture reminds me of some of the equipment I worked on when I started my engineering career in the 1960s. Basically, not much different to what the Victorians would recognize. Later on things got much lighter and more difficult to handle! Oh the joys of making connections using a spanner! By the way, those track relays look like they could switch the London Underground traction current. Hard to believe they're working on 4.5 volts... And as a bit of an afficionado of rack and cabinet wiring, I must say your cabinet looks good - I always found it a quite calming converting a circuit diagram into a nicely wired and dressed cable form. The trick is to get it looking good, and for it to be easy to trace wires when the inevitable faults and modifications crop up. Anyway good job!

    1. Actually Peter those relays pick up at around 0.4V snd hold down to around 0.3V. We run them at around 1.0V on the input. Whilst the battery is 4.5V there is normally a 33 ohm resistor in series with the track feed, dropping as the track length of the circuit increases. This has two roles, one is to limit the voltage at the relay and the other is to limit the current when a vehicle shorts the rails together.
