SSM GNR(I) "S"-class 4-4-0

[Lough Erne]

Horsetan,

 

As far as I am led to believe the RPSI have very few (if any) S class drawings and only one Q class drawing would you believe - which will make rebuilding 131 even more fun! esp when trying to replicate parts lost over the years. Incidentally, I am a semi- regular volunteer at whitehead and could take a few photos when I am down next week if you want to post a list?.

The RPSI could at least have said words to the effect of "No, we can't help, sorry". It's only a few seconds....

Yes please! Basically everything between 171's frames: driving cranks, eccentrics, all motion parts, cylinders, piston glands, etc. Hope I'm not asking too much!

[Mayner]

If you are going to that degree of accuracy, it would probably be a good idea to visit Whitehead and measure up 171s motion the class was "renewed" in the 1930s and the motion may not be the original.

 

An IRRS London Area member Richard McLachlan richardvmcl@aol.com is working on indexing and digitising a large proportion of GNR loco drawings which turned up in a clear out at Inchacore Works in 2011 after being "lost" when Dundalk Works closed after the break up of the GNR.

 

The drawings appear to include component drawings with enough information to build a new full sized locomotive!

[Horsetan]

I'm aware of the late 1930s rebuild, though the frames were pretty much the main visible change.

 

I think the late Tony Miles scratchbuilt his "S" class, and that had working inside motion. Question is, whose drawings did he use?

 

Thanks also for the e-mail address of Mr. McLachlan; I'll get in touch to see if he has managed to unearth any drawings relating to the 1938/39 rebuilding process.

I've sent him an e-mail now....

Heh! so did I.

 

I also checked out the General Assembly drawings on the Manchester site. Massive selection.

Loads of good things in there for the GNR(I) fan.

[Lough Erne]

I seem to recall when I was in inchicore, when the drawings were found 2 very large crates stuffed with drawings as well as the Beyer Peacock drawing cylinders for a few locos but I cant remember what they were now.

 

Horsetan - Will hopefully get photos on sat - A thought - Would any photos of 131 motion be of use as it is very similar and has the benefit of being on the floor in pieces eg close ups of the crossheads , eccentric rods etc

Yes please! In for a penny, in for a Euro!

[Weshty]

Lough Erne, could you possibly get some photos of the 131 in general?

Side elevation, front elevation, close up side elevation of the buffers, and anything at all of the tender?

 

I'm only sorry I didn't snap the living bejayzus out of it when I had the chance back in '84-'86....

Is that the sign of another.....kit?

[Weshty]

Yes. But the year of release is a different matter as she has to get in line behind the D17/D9

[jhb171achill]

Would a D16 be feasible? Or maybe you ned a certain number to justify a production run?

(Serious question)

2020, I think....

[Lough Erne]

Weshty,

 

The tender in theory paired with 131 currently consists of the chassis as the body was completely rotten and broken up in inchicore around 2001 or so. The tender is a more modern tender (not an original Q tender) with roller bearings and was similiar (if not identical) to the old tender at mullingar. The current thinking is to build a Q class shaped tender i.e. straight sides with flared rails on top of the chassis in due course - donations and funding depending.

Was that the LMS Stanier-type tender that she had on the plinth at Dundalk?

I will probably look at doing the Achill Bogie at some stage after the G2 2-4-0 and Midland Standard goods. 2050?.

Lough Erne, thanks for that info. I'm not massively surprised by that news as I remember inspecting the inside of the tender back in '84 and it was just a box of flaking rust.

 

Did they hold onto the tender wheels when they broke her up or did they throw them out too?

[Lough Erne]

The tender was the one that it was paired with for display at Dundalk etc. The only parts left of it today are the wheels, frame, handbrake and a few detail sections. Apart from that, everything above floor level was scrapped as it was rotten and beyond use unfortunately.

[Horsetan]

It was probably only the paint that was holding it together....

[Weshty]

Good to hear that the underframe material has been kept. I would imagine that the above-frame rebuild would chiefly involve sheet metal. A lot easier than having to recast wheels, make up springs, axle guards etc.

[Horsetan]

UPDATE: Mr. McLachlan has replied. He's up to his eyes in Dundalk drawings!

Hope to post an album of photos of 171 then 131 at end of week or at the latest sunday

Excellent, and most appreciated.

Seconded.

[Lough Erne]

In theory an album should have appeared of 171

Found 'em! Excellent run of photos. Think that pretty much confirms I can adapt one of Martin Finney's inside motion kits - the cranks and eccentrics appear similar in shape to those in the GW Pannier, and I could use some other bits from the LSWR T9.

If you want any more photos feel free to ask and I will see what I can do

It just so happens that I have a Finney Pannier inside motion kit lying around....hmmmm....

Horse, you are doing a brilliant model.You are really pushing the envelope. I aspire to such things but I really have not got enough lifetime!! Keep the pictures coming

That last / first photo (photo 16), in which you showed a broadside shot of the "Piston Valves and piston rod detail and gland assembly" - is it possible to get the camera in a bit closer to see how the PVs are actuated? I've enlarged the photo and highlighted the area in light blue to show you what I'm after.....

 

[Mike 84C]

I would say its a rocking shaft driven by the ecentric arm or extension of the ecentric arm. The valve will be pulled or pushed the opposite direction to the ecentric movement. Driven from below.
