Signal Box Diagram Colours

Unread postby Pannier Tank » Wed Jun 28, 2017 8:08 am

I'm in the process of making a Signal Box Diagram / Control Panel for a model of Mortonhampstead BR(W) and would like to know if there was a precedence for colouring the Lines etc on the diagram?
Regards

No doubt you will get a reply from a more knowledgeable reader in due course, but.....

I would imagine that even in BR(W) days the diagram in Moretonhampstead was still the old GWR version. In which case:-
main lines a light grey colour, goods lines a sand colour, sidings blue, signal-box red, platform an orangey/ochre colour. I would guess that the run-round loop would have been blue rather than sand, as it was not a 'goods loop'.

Ironically I drew my own version of M/H many, many years ago, but that was a totally guess having never - and still not - seen any copy of the original drawing.

The diagram from Moretonhampstead box is in existence. I remember seeing it at a Great Western Society function many years ago. It is (was) an Arthur Knight diagram (i.e. with point numbers shown in yellow circles) and was dated 1918, I seem to recall. I believe that Moretonhampstead got a new frame at that time.
