Hi All Im looking for some help as to how i would recreate this scenario, if anyone could help it would be excellent :) Basically there's overhead line maintenance between Stevenage & WGC so i would like to have the class 91 & MK4 Set arrive a Stevenage and have a class 67 couple up to the Class 91 to drag it to Kings Cross. Would it make sense for the class 67 to wait south of Stevenage and then back on the class 91 to go to London? Thanks Scott Log in to reply |

Wouldn't be able to attach a loco at Stevenage, would have to be diesel-hauled from Peterborough.

Ive managed to get them to couple at stevenage platform 1 by reversing the class 67 but as has been said the signalling isn't there for it, im assuming that this would not be prototypical?

If this scenario were to take place (as opposed to a diversion via Hertford) then the consist would either arrive in the area with the loco already attached, or the joining/splitting would take place at Hitchin. There are a few more shunt signals there, and in "real-life" this has always been a more likely place where things like this were done.

The only places that I can see denoted as Permissive are KX, Stevenage Down Slow Platform (EMUs only), Gordon Hill Up Bay, and Hertford North Down Main (EMUs only) and Down Bay.

In reality I would imagine (short of dragging out my Sectional Appendix) that the drag would have to be right through to Peterborough,
Sorry guys, I am in the business of making people wait! Log in to reply |

Surely the current GSR 10.3 (shunting movement made under the authority of a shunt signal) and TCB reg 3.3.1 (stating that permissive regs don't need to be carried out for a shunting movement into an occupied section to attach vehicles etc.) permit the desired movement to be made at either Stevenage or Hitchin, even if the signalling itself doesn't (no suitable shunt signal at the former, and I'm not sure whether the signal back into the Up platform at the latter will come off into an occupied platform) - obviously requiring the loco to be dropped onto the train and not vice-versa - though I'd agree that dragging through from Peterborough, or diverting via Hertford if possible, would be preferable in reality.

" said:It's not a matter of having "more shunt signals", it's whether the stations are signalled permissively.I meant this more as a casual observation rather than a deeper technical comment. I merely took a quick look at the sim to refresh my memory of what signals were available. I didn't have time to test anything out. Also as a life-long observer of this line, I was merely commenting that it has generally always been the case that such moves would be carried out here as opposed to somewhere like Stevenage. I'm also thinking back to when Hitchin was a stabling point and also a fairly busy freight location, and as a result would also have had more staff available to assist - but that's obviously a long time before the likes of Classes 67 and 91.

Of course special instructions could - in theory at least - be issued in the WON for all concerned to observe, to authorise a normally-forbidden procedure and indicate how it was to be carried out and what precautions would be applied to ensure it would be done safely. Whether such things would be done is, of course, a different matter entirely.

There was a (older) WTT available which simulated a weekend blockade at Biggleswade, with drags from WGC to Royston/Cambridge. Diesels were attached just north of WGC at WGC North (rev), and detached in P1, so that the diesel could run via reversing siding and the flyover ready for its next duty. Can't recall whether the attaches were valid signalled moves or not, but was a enjoyable variation for KX. I can only help one person a day. Today's not your day. Tomorrow doesn't look too good either. Log in to reply |

I refreshed that timetable for an intermediate version of KX, and from my memory the loco would sit at Digswell Junction and the train would be signalled on from the rear with an instruction to pass the signal at danger (no relevant calling-on signals there).
