Title: N Gauge Standard Measurements
Post by: Mustermark on August 22, 2011, 01:47:27 AM
I'm just posting this hugely useful link here for future reference.  Newportnobby posted it earlier today and he may be able to supply the original credit for finding it.  Hopefully this is a sensible board for it to live...

For the modern official standards for just about everything from station canopy clearances according to speed to checklists for designing your level crossings.

Anyone know where it went, or its title so I can google it ?

I am trying to decide what the minimum height of the entrance to an engine shed should be in N
Thanks ,,

Mustermark's original link still works but please remember to take into account any underlay beneath the track in your measurements

Yes, thanks, I saw that and I think the measure I want is R, but Oscar said "this is clearer:- " so I wanted to see if there was any further info in it (and a clearer indication of T and S, for curiosity)

Good point about underlay,. Ta.

Yebbut - the diagram shows everything relative to top of rail, so underlay is irrelevant . . .

I have been googling like mad and found an excellent description of the clearances (loading gauges ) required.
Trouble is: it is on another forum (is it ok to link other forums here : some dont like it , I'll go look through the protocols) and secondly cant yet see any copyright notices there so dont know if I should reproduce it here or on my site.

So if anyone is desperate PM me and we'll do it fair-use-quote.

The standard guide to gauges for current UK usage is here

http://www.networkrail.co.uk/aspx/11153.aspx (http://www.networkrail.co.uk/aspx/11153.aspx)

complete with the marvellous quote

Historically, it has been assumed that clearance to the standard gauges (particularly locomotive gauge and W6A) was generally available throughout the network. Recent advances in the recording and analysis of gauge information about the network has identified that, whilst this would be desirable, the reality is not, and has never been, this simple.

http://www.rssb.co.uk/SiteCollectionDocuments/pdf/reports/Research/T926_guide_final.pdf (http://www.rssb.co.uk/SiteCollectionDocuments/pdf/reports/Research/T926_guide_final.pdf)

goes into rather more depth

GC/RT5212 is the whole shebang for the static (ie non train) side of the game

GIRT7016 is the whole platform stuff. It's actually fantastically useful for a modern image modeller as it's freely available (just Google them) and it contains what is pretty much a checklist of all the spacings, lines and signage your model station should have. There are similarly useful ones for level crossings.

It's a little more complicated by historical loading gauges, some bigger some not, and those in turn by pre-grouping ones all of which varied ! Likewise many of the rules for things like platform widths and canopies have changed over time. In particular the further back in time you go the more cautious you need to be of the 3' platform height, with 2'6 and lower becoming more prevalent.

Wow ! Thanks EP but
information overload!!

I'll qualify that by saying " ,, in the steam era c.1944-1964"

The reason I was trying to decide that was because I was scaling the "Wordsworth" kits from 00 to N and wanted to check that my printer was behaving.

No worries tho' cos Joe 90 has solved the prob by referencing door heights ! http://www.ngaugeforum.co.uk/SMFN/index.php?topic=11121.msg116428#msg116428 (http://www.ngaugeforum.co.uk/SMFN/index.php?topic=11121.msg116428#msg116428)

Thanks.

It depends where - the different company gauges varied - even within the big four. A GCR loco would have performed several minor unapproved alterations to the fixtures if run on the east coast mainline for example 8)

About 13ft is a good guide, bit lower in some cases. Much lower in a few (eg the met)

It depends where
Ive not tracked down any very good sources on the internet yet but I'm thinking Durran Hill shed Carlisle.
It was not far from where the Settle-Carlisle entered (our)suburbs of Carlisle.
I thought at the time that it was an RAF depot, (14MU being not far away) but dont know where I got that idea, internet searches suggest it was just a minor Midland shed ??

Thank you for this Mustermark and NPN, this will be a great help to me in some more scratch building when i get around to it.     :) :)
