Back in the day I studied psychology, and got fed up with people saying, “I could have told you that: it’s obvious, innit?” To which my usual response was, “Yes, but you didn’t. And neither did anyone else until so and so came up with the idea.” I mention this as I look at that tool, and think, that is so simple, so elegant, and so effective that I wonder why I didn’t think of such a tool? Brilliant!

pre-grouping and never-grouped narrow gauge
Regularity replied to cornamuse's topic in Pre-Grouping - Modelling & Prototype
That’s rather nice. Unfortunately, it had me looking back through the thread to find out more, only to discover the loss of images. :( -
Fair enough. ”Different to” reflects my regional and class background*, but alternate has a specific meaning, which is not the same meaning as alternative, otherwise we don’t need the latter word. * There are a surprising number of such variations within England, which operate independently of accent. The “worst” culprit is “while”, which is used hereabouts (L&YR territory**) to mean “until”, rather than “during” or “if” which caused a number of fatal accidents on open level crossings as the signs used to say “Do not cross the lines while the light is out.” ** Not where I am from, but where I live.

There is also the difference between what was supposed to happen - drawing to a complete stop - and what actually happened, where the signalman would observe that the driver had the train under control (moving very slowly) and would drop the board so that the driver didn’t have to stop, to avoid (or reduce) the risk of a coupling snatch. -

Seems reasonable to me! (But it would be fun!) There is also the possibility of a gantry…. I have assumed here that P4 is unidirectional, but P3 bidirectional. G for foods, L for loop. L and P4 are subsidiary arms (shunting only). Also, what is the purpose of the siding at the west of P3? Is it a safety-siding, in which case the ground discs are not needed, or is it needed at all? And I have added 4 more catch points… -

Then there’s the possibility of having a calling-on arm beneath each stop signal. To be kind, you might not need it for the goods route, so maybe only 9 arms… -

I believe that there would be a lever for each route, pulling one of them would pull the home signal off whilst displaying the appropriate route. -
My memory of CJF’s goods shed was a two-road shed with central platform, of some length compared to a branchline goods shed, such as would be used for deliveries to the local shops. For a terminus in a major city, this traffic would arrive in a variety of opens, vans and NPCS, with the wagons at least coming from quite a few companies even before traffic pooling. It would also be worked outside of the rush hours, as during quieter periods, only two or even one or the platforms would be required for passenger trains.

Did that (albeit slightly longer) when I was about 13. Didn’t know enough about how to arrange power to the rails, though, and hand-pushing locos one and off felt a bit toy-like. It does work, though.

Not sure that the pre-grouping scene is ideal territory for anyone wanting a “quick fix”, but this not too expensive kit for 0-16.5 has a deck scaling out to 53’ in 4mm scale, and should be modifiable with new handrails, etc. https://www.kitwoodhillmodels.com/on30-9-pit-turntable/

There may be a detailed track plan in GE Engine sheds, failing that, perusal of photographs. Do you have the relevant Oakwood Press book? I am going to attempt to answer some of your questions, but my perspective is that on an interested amateur rather than professional signaller! You don’t need a ground signal it is duplicates the permission that would be provided by a stop signal, I.e. that the train can proceed up to the next signal on that route. You might see one for a diverging route from that position. If the permission was to enter a section of track which may be occupied, then a calling-on subsidiary arm would be required - and the driver needs to move slowly and be prepared to stop at very short notice. (E.g. a loco coming onto the rear of a set of coaches in a platform.) Locos leaving p3/4 for the loco depot would have a ground/subsidiary signal, one for each route, as the starting signals will be used for going to the branch/mainline, and not the loco depot. Think of them as being akin to junction signals in this respect, as they apply to a different route. Therefore, locos going on shed are not passing a signal at danger, as the signal at danger does not apply to their route. I am not sure about the green dot position: branch trains could presumably gain access to/from platforms 1 and 2, and you have different options with what to do about this. 1) require locos to go further, to wherever the signals are for arriving trains, and be signalled from there using the stop signals. 2) ground signal(s) as you indicate, but there is potential for confusion in the arrangement as this is a turnout used on both routes for passenger trains. 3) have a full signal at this place, with arms for each route (or at least each platform, and a ground signal for other routes) with a single arm stop signal on the main outside of all the pointwork, and a two-arm signal on the branch, these to be for arriving trains and giving permission to proceed only as far as the signal at the green dot. You don’t need a ground signal for every possible move, unless you are modelling the NER. It depends on frequency and safety: for less-common moves, the signalman might wave a green flag (or just give a flick of the wrist if no officials were present!) An “advance starter” would be helpful, and serve as the limit of shunt unless there was a “shunt ahead” subsidiary signal on it. It also means that you don’t have to have a “full” signal for departure from the goods yard, so that then is up to you. Just because it is on the wrong side of the line, doesn’t mean it has to have a bracket, either. But if you want to, it’s better practice, depending on era/company. Hope that helps. -

That’s a very disrespectful way to refer to your Grandmother… -

They did connect, but it required pulling some points off, via a crossover in a scissors formation, and the normal route headed towards non-running lines. Effectively, there were already points providing safety, so no catch points required. -
Entirely depends on your sources of inspiration, and the (presumed, if you are inventing somewhere completely fictitious) topography of the surrounding area. This will be further driven by other matters such as if you need access to platform ends, how you are going to operate points and signals, and what sort of couplings you are using. The only person who knows what looks best for you, is you.
