Phil,
It would be finger trouble, you did the 'place in line' twice, but both times for the same image, hence the other image just appears at the bottom.
You can just go back in and edit it.

Tripcocks were required on the widened lines and post steam were fitted to the diesels working there, 23, 24, 31 etc. Also required for the Hammersmith and City and 3 2251 class locos had tripcocks for that. Trains running into Paddington Suburban (platforms 13 - 16) also required tripcocks which wo...

That picture was published by the NRM and offered publicly for use as a screensaver.

While I'm thinking about it I'm also thinking about, but rather more hazily, the only bit of wholly cosmetic modelling on the project, the cylinder drain cocks. I'm not terribly acquainted with them visually, and photos don't exactly home in on those details. An impression is all that's really need...

My recollection of looking down on passing trains from overbridges back in the 50s/60s is that the roofs were never clean, except the occasional ex-works example, as in the photos above but rather filthy with soot including a good supply of small cinders from the loco exhaust so quite a textured eff...

I do have a curiosity question for Alloa experts. Is the double junction diamond just near the trap point a switched crossing? I assume it should be, even in 00. Most low speed double junctions in the Uk manage without switched diamonds, ie the K crossings will be 1:8 or less. Switched diamonds are...

I have a few of these in use, they run very well and my rubber is not yet in need of replacement.

'Traditional' semaphore signals with wooden posts were braced by guy lines, which countered any instability in the potentially flimsy structure itself. Not just wooden ones, tubular and lattice post steel signals commonly were guyed also. Getting back to the water tank, I assume the cage on the lad...

You still need a set when you have joggles. The joggle is to allow for a thicker switch tip. The set is to make the stockrail sit at the same angle as the planing on the back of the switch so the stock rail and switch fit together properly when the switch is closed and both gauge and flangeway are p...

Colin markets it just as much as he markets anything else, ie it is in his current calalogue.

I recently assembled a chassis using the supplied P4 spacers and then discovered that the wheelsets had no sideplay whatsoever and would not turn freely. So have just dismantled it to start again with the EM spacers. One problem is that the rear bosses on wheels may not be what the chassis designer ...

Since you already have them, put some temporarily in appropriate places (bluetack) and test it out. I would think it highly unlikely that there would be any problem, locos full of magnets already run around, interference with servos usually comes from electric currents rather than passing magnetic f...

Ten pounds a meter it seems nowadays.

A quick google on "wooden gutters" gets plenty of info and pictures.

It is 1mm so really is a tad big for 4mm domestic guttering (which would be 3" or 4") but it is fair to say you won't notice. Well, on my reckoning 1mm is 3" which I would see as a bit small, 4" would be better. Used to be that umbrella ribs were the favoured item for this. But ...

I doubt you will make any more sense out of this unless you can pin down the dates when data for each of these plans was compiled and relate that to signalling alterations.

Shotton's lack of a box is a bit of a puzzle. Here is an extract from the Railway Magazine's 'Gradients of the British Main-line Railways' 1947 edition, suggesting that there was a block post at Shotton: There does not seem to be any reason for a block post at Shotton, the Queensferry - CQ1 section...

Or would it be more accurate to say that the convention is to draw a slotting shadow for any distant that is controlled by at least two levers in addition to the slot for the stop signal above, irrespective of whether those distant levers are in one box or in different boxes? Correct. The most obvi...

Herewith the promised scan. The relevant text is on the left hand page. Taken from IRSE green booklet No 10, mechanical signalling Equipment.
For LQ signals the arm drive has to be reversed to use push rods, not pull wires.

I found Keith's explanation very lucid, and the conclusion I drew from it is that the distant beneath Connah's Quay No.2 up starting signal was effectively triple slotted by CQ No.2 and CQ No.1 and Shotton, which is the next block post beyond CQ No.1, and that it was because this distant related bo...

Why then is the slot for the distant below 13 specifically identified, when that for 2 is not? As we do not know the conventions used, this could be a) because the distant is operated by two boxes [which cannot include No.1 box] Yes, which is what I tried to say above! Sorry if it was not clear. I ...

Either of those options and probably more, afraid I don't know details of specific LNWR examples, or any others really.
