At the present time Stafford is controlled by 2 large (electro) mechanical boxes. Real life has a bit to catch-up with SimSIG  In the meantime these pictures might be of interest: https://www.flickr.com/photos/llangollen_signalman/sets/72157645111410143/ Stafford No 5 is single manned and involves a lot of walking for the Signaller. Stafford No 4 is double manned except for the Sunday night shift. Log in to reply The following users said thank you: 58050, Finger, Class 86, BarryM, Temple Meads, belly buster |

Thank you for that very interesting Topic! One question. It looks like that the Salop Sidings have been disconnected? Cheers Log in to reply |

Emergency closing switch is one I've never seen before. So how does that work then?

So how does that work then?Rather than guess I have asked the question on another forum and will post reply here if I get one. "It was designed to enable the signal boxes either side of the switched out box to run trains reg 3.5 ( one at a time) the box switching out would pull off main line signals up & down then operate the closing switch. Then the signals would operate like autos." I am guessing from the 'Emergency' tag that this was the exception rather than the rule - e.g. Signaller completely out of ours and relief still in transit. Clearly not a conventional switching out arrangement where normal operations can continue as the trains effectively go into a black hole - hence one at a time. Responder did refer to the 'Emergency' tag being covered over in one area nearby when Management were trying to keep staff costs down. Log in to reply The following user said thank you: kbarber |

Curious that the expense of adding one was judged worthwhile - being a box that's (double) manned 24-7, I can't imagine many situations where it would be likely for the relief to be sufficiently delayed beyond the normal changeover time for the other man (men) to be over hours.

That does make a certain sense. TCB over long distances wasn't terribly common in those days - over 50 years ago now!!! Remember there weren't the number of telephones about either; I can remember my father, as a senior relief signalman on the GN Main Line, being summoned to work by telephone message (maybe even telegraph - the single-needle was still active in those days) delivered by the porter from the local station. The AB Regulations had plenty of provisions for emergency working, including Reg 25(a)iv which covered time-interval working (and had we had a block failure at Junction Road I could see myself using that regulation as late as 1979, such was the state of the telephones in that area). Block switches were also common, sometimes in surprisingly busy signalboxes. Even Finchley Road (Midland) had one, in spite of controlling the entrance to the Belsize Tunnel bottleneck! I wonder whether the emergency closing switches at Stafford require(d) the fast lines to be set towards the platform loops? Log in to reply |
