    And finally for now, a couple of projects I've been working on.
    First up is an ex-LMS CCT. This is an Etched Pixel kit which comes with a 3D printed shell, to which the etched body sides and ends are attached. The roof utilised the 3D structure. The chassis is an N Gauge Society ex-LMS Stove R chassis with some under carriage equipment removed.

    It is primed here, awaiting top coat of BR Maroon (Halfords Ford Burgundy Red):

    Secondly, this is a Greseley Full Brake (BG). This model is the N Gauge Society kit, sadly unavailable at present, but one I picked up for a good price on Ebay. It comes with parts for a chassis and sides, similar to a traditonal "airfix' kit.

    It is also in primer awaiting a top coat of BR Maroon for the sides and black ends. After painting it will gain gangways and couplings:

    Glasgow North continues to develop whilst await for the garage to be converted (a letter of instruction is going out from the architects this week, so at last some movement).
    Two drawings below. The first shows the upper (main) level. You'll see the Nelevator has been moved to a peninsula in the middle of the room. This is to allow the stretch along the top wall to have a nice long scenic section so that trains aren't just "visible" on the station board.
    The tunnel section in the top left corner, in pretend land, is around 1/2 to 3/4 mile long.
    A few inches below that board is the fiddle yard for through freight trains that have bypassed the terminus station.
    There is a line now that snakes in under the terminus station and emerges on the left hand baseboard. This will be an urban cement unloading facility.

    Hi all,

    I'm looking for some Signalling help!



    Can any of you tell me if my proposed signalling thoughts are on the right lines?

    [​IMG]Glasgow Northish Terminous CENTRE NELEVATOR & Redesigned Curve by ScottyStitch, on Flickr

    The main line looping across the top of the plan is restricted to 40 mph running in both directions. The station approach and the through line will be restricted to 30 mph in both directions.

    The platform section should be obvious. To the left in lilac is a carriage shed, in red a DMU fuelling point and in purple further left, in the corner is a diesel fuelling and light-servicing point.

    I am suggesting that all semaphores have been ripped out and replaced by coloured light signals, controlled from a power box. Perth had this kind of treatment in the early 60s, so I think that's plausible.



    [​IMG]Glasgow Northish Terminous CENTRE NELEVATOR & Redesigned Curve - Station Starters by ScottyStitch, on Flickr
    I have given each platform a starter signal. Should these be three or two aspect? The two lines into and out of the station are not bi-directional. Should the starters have some kind of route indicator on them? I'm guessing not.

    At the bottom of the descent into the subterranean tunnel of the through line I have placed a signal. About a quarter mile after entry into the subsurface, there is a junction. Should this signal be two or three aspect?




    [​IMG]Glasgow Northish Terminous CENTRE NELEVATOR & Redesigned Curve - Approach Crossovers by ScottyStitch, on Flickr

    I have placed a signal just before the scissors crossing on the arrival line, I am proposing a theatre style route indicator on top. Again what aspect should the signal be. I am assuming two.

    I have placed a similar signal on the loop from the carriage/diesel fuelling areas. Should this just be a ground signal?




    [​IMG]Glasgow Northish Terminous CENTRE NELEVATOR & Redesigned Curve - Approach by ScottyStitch, on Flickr

    On the departure line I have placed a signal to protect the junction and a similar one on the carriage/diesel fueling areas. You'll have guessed by now I don't know how many aspects to use.

    I have also placed one on the corresponding through line.

    There is another signal on the arrival line, again protecting the junction. This one would need some form of route Identification. What would be more likely, A theatre box or a feather? I'm think theatre box to prepare the driver for the arrival platform as well as indicate the branch for the through line.




    [​IMG]Glasgow Northish Terminous CENTRE NELEVATOR & Redesigned Curve - Departure by ScottyStitch, on Flickr
    Finally there is departure signal just before the obligatory/cliche'd tunnel. Would that be right or is it too close to the last signal, further back at the junction?





    I am assuming all other turnouts would be protected by ground signals. Would the carriage/fueling areas be power operated points/ground signals or would they use a ground frame?



    All help and advice would be gratefully received in this regard. It doesn't have to be 100% accurate, but I'd like it to be plausible at least.



    I hope I have explained things well enough.....



    Best

    Scott

    I'm afraid its beyond me :( I find the signalling difficult to understand but I'm sure that there will be others that can shine some light on it. Very impressive plan.:thumbs:

    I've just read this thread for the first time - looks like a great project you have there. I hope I can help a bit with your signalling but I would recommend you read Stanley Hall's "Modern Signalling Handbook " which you can get on Amazon for around a fiver. Well worth having. Lets assume that you are going with three aspect signalling throughout so the aspect is either red (next signal section occupied)/yellow (next signal free, the one after that occupied) or green (next two sections free) so for trains departing your station all signals will have three aspects. Junctions can be dealt with by theatre box indicators or feathers indicating the diverging route.
    In the arriving direction three aspects could apply until you reach your terminus. If you consider the red light on your buffer stop as a red signal then the one before the platforms only need be two aspects as the driver will only ever see a red or yellow aspect. The one before that would be three aspect.
    There are single aspect signals where the aspect is changed using different coloured lenses which might be used where lineside clutter means this is a better solution than a multi aspect signal.
    Your layout will require shunt signals for various moves and attaching locomotives (and vans) in platforms. These are often posted on main siganls or on the ground. You should plan these out even if you plan to add these later.
    Hope that helps

    Dave

    Excellent, thanks Dave. That confirms hunches and thoughts from other sources, and looking at real world examples from the era (1960s)

    So three aspect it is, with the exception of the two inbound at the scissors which will be two aspect with theatre boards. Shunt signals on all the platform starters and ground signals on all other points.
