  1. Glad you got it sorted. Mr Random really wasn’t your friend this time, was he! Paul.
  2. Would like to have attended the York show to see Wentworth, but I’m expected elsewhere. Family comes first. Paul.
  3. Not come across a verynear before. I rather like it. Paul.
  4. The last incarnation of the GWR locking frame built at Reading signal works. Obvious to signal engineers (particularly WR) and meaningless to almost anybody else !! Paul.
  5. With my user name, I can do nothing but approve, having walked past it on many an occasion. Paul.
  6. No, the stage before that - creating the potholes for someone else to fill in later. Paul.
  7. Do you have to arrange for the hire car to be returned when you get a changed turn at short notice? Or do Control do Road vehicles too? Paul.
  8. Assuming your not using a live frame on one side, or having front axle only for one side, don’t you need a further cut in the PCBs? Paul.
  9. Back in the early 80s, sand traffic was routed off the ECML onto the GN/GE route between Doncaster and Peterborough because leaking sand was causing too much delay on the main line. (Got into the clamp lock point mechanisms and ground them away til they failed.) Paul.
  10. No help here, but those sound like the problems i have had, so thanks for the heads up on where to go looking. Paul.
  11. More thinking aloud then! Really off the wall (and I’d want some input from other engineers and operators to confirm I’m not raving . . .) operate the loop trap off the FPL lever, just leaving three ends on the point lever. Or, more conventional, operate the siding traps off a separate lever and probably the single hand point too. (Risk management - don’t want a guard/shunter forgetting and either running through traps after just swinging the hand points, or dropping off on mis set hand points after just operating the traps.) i.e. for modelling purposes, an extra lever on the GF. Paul.
  12. Electric token M’head to Bourne End. That released the GF at Bourne End which in turn released the staff for Bourne End to Marlow. With the train shut in to the Marlow section the token could be handed back and another train run down to Bourne End. That used to be the peak operation, off peak one train down to Marlow and all the way back. Paul.
  13. First one I’ve seen with the branding on. Is it just the end cars with all the others still white? Paul.
  14. Technically, yes. With a trained signalman (in those days) and not too far from the box, no problem. But with a guard, even if they had more practice back in those days, I’m less sure. The GF would be right on top of the points, so not a desperately long run, but still not convinced. I’m currently about 48 1/2 years ago reading the Oxford Techs fault book: Radley GF O.O.O. Guard instructed in use of ground frame. . . . But as well as keeping the signalling as simple as possible, the pway should also be the minimum required. Is there a need to both sand sidings to be accessed from the running line? Making the slip two single ends (or a Barry slip if you must), saves one of the traps. A bit more simplification could get it down to one trap. Empties in the exchange road. ES&T Propel fulls down onto empties, shunt out to 2nd siding, shunt fulls to exchange, back onto empties and take away. Likewise, the BR train - down into loop, run round and brake into platform (never shunt with a brake, spills the tea, spoils the fire) collect fulls into platform with brake, empties into exchange siding, back onto train in platform and away. Obviously, not all achieved in one session. And I’m pleased that your shunting timetable doesn’t start until the passenger is back down at Berwick. Paul.
  15. Some may say that, I couldn’t possibly comment! Paul.
  16. As far as I know NSKT was a BR invention, and not that early. Shut in ground frames with an intermediate instrument were about earlier I think, but my assumption is that there would have been a signalman at each end. This century we did something clever at Stranraer to permit staff working most of the time but token working when two trains needed to be down there at the same time - that did require the box to be staffed for one shift a week. Thinking ‘out loud’, I could envisage a staff released by one lever at Berwick (for the EMU) (could be a mechanical release) interlocked with a separate lever for the shut in staff (released electrically). Each reverse to release the staff and requiring staff in to be normalised. The clever bit is allowing the release lever for the ‘shut in’ staff to be normalised if the staff was locked in at the Cuckmere end. From the guards point of view, this arrangement is very similar to a normal shut in GF, except that the staff is received from the signaller at Berwick and returned there later, but the GF operation is no different. Having seen examples of clever stuff that SR engineers did, this seems well within the sort of things they might have tried. Paul.
  17. There is a ZN218.6 and a ZN218.4.2 and they are not the same (to do with whether the extra 2 outputs are logic level or not (‘12V’?). So I would imagine that the RoS is similar. I haven’t managed to get all the lights to work on my SPCs and I suspect this might be something to do with it. Paul.
  18. And to which service do you propose to allocate this loco? Paul.
  19. It was an Irn Bru advert mounted on the wall of (I think) Caledonian Chambers (part of Central Station) facing up Renfield St. in my time, it was a large clock with blue hands and orange numerals (and some Irn Bru advertising). Very useful if you were running down Renfield St a bit tight for a train! Internet searches reveal previous incarnations of the advert, but I haven’t found one of the clock. After privatisation it was taken down, because (allegedly) no-one knew who could authorise it to remain. (I suspect the wall was ScotRail in Caley Chambers and the roof beneath it was whoever owned Central Hotel.). Strangely, it seemed no bother to find out the ownership to effect a new electronic advertising sign in its place . . . Paul.
  20. Not the right station for the Irn Bru clock (mores the pity!!). Paul.
  21. Nicely done. I rather like it. Paul.
  22. Thank you - should have gone to . . . Now I look properly I can see that the shield is fixed to the post not the arm. I wonder if it’s the same Annett as in GF release instruments. Yes, a plate in place of the green glass. Paul.
  23. I’ve just lost half an hour of my life. And really enjoyed it! Paul.
  24. Usually in conjunction with a colour light head for Y (YY) G at the fringes of a colourlight area. The Southern were particularly fond of that fringing arrangement. Perhaps that part is yet to come. Paul. See below for correct explanation!
