Nothing really to do with the panel, more to do with the interlocking. It can be done very simply with Western Region E10k interlockings, not sure about some of the other 1960s types. Log in to reply |

" said:If I remember correctly, Euston was built fairly early on in the development of the NX technology. Did other boxes built in its era have automatic re-clear functions for controlled signals? I wonder if that came in later on, hence the confusing omission. I'm pretty certain Willesden, Watford, Bletchley and Rugby had some A buttons, so I really don't know why none ever appeared at Euston. Edit to add: just confirmed New Street had plenty of A buttons. All the boxes I mentioned were broadly similar vintage to Euston. Last edited: 04/01/2015 at 14:48 by kbarber Reason: Further information Log in to reply |

Could it be with Euston it was preferable to have the signalman set each route manually to avoid overlooking a train and sending it the wrong way by forgetting to pull the auto?

" said:Nothing really to do with the panel, more to do with the interlocking.Euston was Westpac Mk1, same as Birmingham New Street is now, and Soho which has lots of auto buttons. Now, in Mk4 there were a lot of things that weren't in Mk3, same for 3 vs 2, 2 vs 1, so it's feasible though unlikely that that function is outside of the geographic standard circuitry. Euston pre-dated New Street by around a year. IIRC the Southern panels that had a n-train auto facility (press it 3 times and the route will stay set for three trains and then cancel) had this functionality in the panel, not the interlocking.

Some have had auto buttons added later. In other areas, enabling ARS subareas turned off auto buttons, and turning on auto buttons would disable subareas; in other areas still both could be used at the same time. Nothing like standards when there are so many to choose from! SimSig Boss Log in to reply |

ARS is fine when it works, and causes chaos if it fails. Do IECCs still have days when the Signalman are supposed to run the box without the ARS? Log in to reply |

" said:Do IECCs still have days when the Signalman are supposed to run the box without the ARS?While I recall such really did happen somewhere, it certainly wasn't widespread. In some places it's virtually impossible to run the service without ARS. These days the control areas - even with ARS - are smaller so the signallers can handle it without ARS.

I thought I read somewhere that signalmen were required to do some manual operation (I think I recall it being 2 hours) during evey shift - but they weren't necessarily required to run their whole control area manually. So there was a tendency to leave the easy bits on ARS and to take manual control of the complex (= interesting) bit to get their manual hours in.
