shed 7 - Loading gauge

For discussion of the issues faced when building a model or layout - how to replicate wood, what glues to use, exactly how much weathering can a Gnat take, a good source of detailing accessories - you get the picture, I'm sure.

shed 7 - Loading gauge

Postby nobby » Wed Aug 06, 2008 4:52 pm

I've read several times about loading and wagons (particularly) being to big for it.
I understand what loading gauge is for full size railways but what are the relevant dimensions in Gn15?

cheers

Simple really, and this is a personal view, It's up to you :shock: Depends on your loco's, stock etc.

I'm sure there are some "guide lines" if your using Steve's kits for instance but other than that suck it and see! :D

Gn15 gives you this freedom. Don't get snowed under with sensible stuff.

Depends if you want to follow prototypical practices. If so, most places in the world use the same formula for MAXIMUM loading gauge, which is related to gauge. It is 3.25 x gauge for width and 5.25 x gauge for height. Generally this is appled to all railways of 15" gauge and above (well 381mm to be exact, at least in the UK). Below 15" gauge, different regulations usually apply.

Technical answer. Much better than my drivel!

Nobby whatever clearances you decide upon there will come a time when you build or acquire something that doesn't fit. Simple solution to that is item in question has restricted movements or you rework the offending building/scenic item to suit. :wink:
I know that it's not just me that has experienced this situation, even worse when you find the problem hours before a show. :oops:
So little time, so many ideas!!!!! GerryB.

My models are probably close to the maximum of what would look relatively sensible. I tend to build rolling stock and locos to a width of about 50mm occasionally reaching 52mm. Anything of that size and under should look pretty realistic. :wink:

I think this loco's about 3 inches wide, and 5 inches tall? It runs (just ;) ), but I think the smaller 4 wheeled stuff is more versatile.

Dear Gn15 crew,

If memory serves, :idea:

wasn't it the doyen of 15"gauge railways, one Sir A. Heywood, who set out the "3 X gauge" rule for body width,

because 3 X 15" gauge = 45" - 48" over body approx max,

which is just wide enough for a person to be seated,
and permit other person to walk past them down the "side aisle" of a passenger carriage,

without being "unduly unstable" :?:

(Or am I just mistaking Urban Legend as Fact again? :? )
Happy Modelling,
Aim to Improve,
Prof Klyzlr

I know that I have trouble fitting into a Heywood closed coach. Those who have met me will understand the problem. I tried it once at Perrygrove and gave up. The space is very cramped. I susdpect that loading gauge depended on how much would fit around the various lineside obstructions. I seem to remember a photograph of the 15 inch gauge Sand Hutton with a very well loaded hay train.

This is just the information I'm after. Viva le Gnatterbox :)
