GNR Locomotive Diagrams

[jhb171achill]

I thought there was a section on here for posting plans, drawings and diagrams of prototypes. If so, perhaps admins might shift this entire post there.

Otherwise I will continue to post here.

In recent times, we’ve seen a fair amount of interest in GNR scratchbuilds, so I thought I’d post some GA drawings here, which will be useful to check overall dimensions.

I have the 1958 Dundalk Works book of loco drawings. This contains details of every class then technically on the books, whether actually operational or not.

There are dozens of them. If I post them all (more than happy to do so) the site will be bombarded with them for days.

Possibly better if I put a few up selectively; thus, any requests?

Im out’n’about right now - will post a few samples when I’m home.

Thank you !

Thanks JHB!

I don't suppose you have the GNR wagon diagrams too?

I've been trying to buy a copy of those from the IRRS but there's only an email address for contact and my emails have gone unanswered.

With the society being a voulntary body, and currently chronically short of active volunteers in the archive, I'm hearing many queries are going unanaswered - hopefully things will improve in time. As far as diagrams are concenred, no, I don't think I've any GNR stuff but I will have a look. I know I don't have any carriage stuff.

[jhb171achill]

I’m afraid I’ve nothing on wagons….

Hi MOL_PMB

if you are looking for the GNR Carriage Diagrams Part 5 Non Passenger Stock. this was produced around 2014 by Richard MacLaghlan. Contact Leslie McAlister (ProvincialWagons) who may be able to help.

[jhb171achill]

Re. the locos, if anyone wants a proper paper scan of any of the drawings, let me know. I expect cost plus postage to be only a few euros. Or any further requests here - there's Q, SG3, D, P, PP, and all the rest, plus the crane tank and the BCDR 4.6.4T! They probably copied that when they were considering a six-coupled tank engine of some sort at one time.

Thanks Mike!
It’s the GNR goods wagon diagram book WD002 I’m looking for. 
The IRRS list it as available for sale in digital formal on their website:

https://irrs.ie/wp-content/uploads/2019/02/Digital-Drawings-List-22-UK.pdf

But actually getting hold of it seems challenging!

Not that I know of, Josh, but I’ll have a look. There were many different variants, and many were altered (sometimes more than once) during their lives…

Thanks very much @jhb171achill 
There awfully awkward to find online or even in books

At one stage the Chief Mechanical Engineers Office at Inchacore supplied locomotive and rolling stock drawings to enthusiasts (free of charge) upon request, but may no longer be responding to requests from enthusiasts and may no longer hold drawings of older stock such as the Laminates.

I have  diagrams of 64 and 70 seat Laminate coaches supplied by CMEs Office about 20 or so years ago, and will post in the Resources section when I find time, Pauls post also reminds me that I need to scan my collection of GN Wagon Diagrams!

Thanks, JB, for stating the situation which is accurate.

Richard McLachlan is in the process of making this information more easily available, but he has other priorities, like anyone else. The loss of Anthony McD, his Dublin right hand man, really took the wind out of a great piece of work which they were doing together.

If people contact me, ON EMAIL please, I'll try and help.

Many thanks to Leslie and Richard for taking payment and sending the wagon diagram set I was looking for. 

I have some research work to do now!

I thought it was from the drawing office themselves and do u know when exactly was the time when they gave drawings out free of charge

I last received Park Royal & Laminate diagrams (FOC) from the CMEs office about 20 years ago.

It might be worth contactiong IE directly if your looking for drawings or diagrams of stock thats currently in service.

would you have any drawings of the 0-6-0 Crane Loco No.31 ?

they are hard to find and I'm using photo's plus some  photos / drawings of Indian and Australian crane loco's also built by Hawthorn Leslie to model this loco.

RT class 0.6.4T

 

[jhb171achill]

And now here’s one for yiz.

GNR No. 203, not known to have hauled the Enterprise, Bundoran Express, or Foyle Road goods….

It was owned by contractor Robert Worthington & Co, who bought it for building the Castleblayney, Keady & Armagh Railway. The GNR acquired it - though the purpose remains unknown - once that line was finished. It seemingly was little used and had been disposed of by 1930. It was by some way the smallest loco the GNR ever possessed. 

Its official number was probably never carried - though years later a different loco took on No. 203, of course.

One regular characteristic of these GNR diagrams is that you only get the side-view measurements only - no end-on, or plan views.

For the engines that were supplied to the GNRI by Beyer-Peacock, you do get the full works, but the trouble is that you have to know where to find them - The Manchester Museum of Science and Industry has them, but they are no longer accessible online after yet another reorganisation. Access to the Great Central Railway locomotive diagrams has also been lost.

Ive contacted them and only got one but have seen others from FOIs i asked for rail maintenance vehicles , mk3s etc; but no luck but im mainly after older stuff like mk3s and lamiante drawings

Also what does FOC stand for?

I posted a set of Laminate Diagrams in the Resources section of this Newsgroup and will post further CIE diesel loco, coach and wagon drawings when I have the time.

IE may have disposed of drawings of withdrawn/scrapped stock as they are no longer of relevance to Irish Rail, when I requested the Laminate & Park Royal drawings some of these coaches were running on the system in RPSI service.

Many thanks John, very useful. 

Interesting to see the different arrangements of vestibules and toilets on the two types, and the high proportion of smoking accommodation.

Photographic evidence indicates that the 1429-1448 type were delivered in 'silver' (unpainted aluminium) but the the 1449-1496 type were green from new.

 

Edit: there's a nice close-up view of one end of a 1429-1448 type coach in the book 'Bulleid and the Turf Burner', page 65.

This photo dated October 1957 shows some interesting details:

• The small window in the toilet compartment was frosted, as one would expect, but the adjacent one above the handbasin was clear.
• The large windows in the saloon had curtains on their lower part, which were hung from a rail just below the opening vents. 
• The panelling and beading of the sides and roof is shown very clearly, also the door furniture.

Some of the autumn 1957 tests of CC1 used a full train of these coaches (with a tin van on the back) which must have looked shiny!

Sorry if this has been stated earlier in this thread which I have only been casually been following (except when I helped Paul to get his wagon drawings) - anyway:

The Society has published:

GNR T1 and T2 Tanks

Compound

VS

U Class

SG2 Class

and SG3

They're all around £50 for a digital copy - you could buiild a 12 inches to the foot model from them. The job of scanning the ancient sheets needed a lot of setting up and skill.

The plan is to make the lists etc accessible on the Society's new website, so be patient.

If folk need things sooner, let me know what you are after - email preferred:

lesliemcallister@aol.com

and I'll get on the Drawings archivist who will shortly be in Switzerland for the summer (but I know where!).

Delighted to know Mayner 

The disposal of drawings is reasonable but also disappointing there was no preservation for them 

I was told by someone from IRRS in bangor about loads of drawings being disposed of in boradstone and inchicore but thankfully the likes of IRRS have gotten what they could find
