Signal Box Windows

Post by Orbiston » Sat Jul 20, 2019 8:45 am

Were there standard dimensions for Southern District S4 signal boxes ie the tall narrow ones with two panes?

Yes, there are drawings in Jim Summers' book on signalling. I'm on holiday at the moment, so can't quote the dimensions.

Thanks Jim,
Yes there are a couple of drawings which I actually find quite hard to read. (not to criticise the wonderful book). I make the window dimensions to be 6'6" X 2'3". But is that standard?

I have a plan of the standard box for Southern & Eastern Sections, it doesn't have a date or a drawing number.

I have the measurements taken from Haughhead Junction just before it was demolished. I'll check them when I get home next week, but these figures ring a bell. I do remember that the astrigals were 3" thick and the corner posts 9"x9". That ties in with Jim's drawing - (8x2'3")+(7x3")+(2x9")=21'3".

Both Jims - absolutely brilliant guys - thank you very much. I'm hoping to produce a set of laser cuttings which I hope will benefit everybody.

Back home now and have dug out the dimensions I took off Haughead Junction box, which concur with those in the drawings posted by Jim Mac. A couple of dimensions not given on the drawing are the framing around the actual window which was 2" wide and the position of the horizontal frame (also 2" wide) whose top was 24" below the top of the window.

I also have dimensions of the stairway and railings, the latter having three rails rather than the two in Jim's drawing, if they would be of interest.

Thanks Jim,
the window info was great, thank you.
I'm hoping to move the topic to Modelling Resources shortly and invite comments. I'd be interested in what you think then. I'm aiming to produce a fairly basic shell that people can augment with available proprietary products or detail themselves to make it as cheap as possible.
