The only 40 ton Coal Wagons I know off are the NER design of Hoppers but with plate bogies

[jwealleans]

I'm pretty sure the GC had some 40 ton loco coal wagons.

[Blink Bonny]

Ay up!

The LNER exhibited a 40 ton bogie hopper at the British Empire Exhibition in 1925. According to LNER reflections, 30 were built by the Leeds Forge Co in 1923 and used in the Ashington area. 15 of those behind Graeme's beastie. Yes!

[S.A.C. Martin]

A Gresley machine then, based on the LNER reference above and Graeme's previous predilections with un-built Gresley designs...?

Is there such a thing as a Gresley 2-10-2?! I could almost see a stretched P1 with an 8 wheel bogie tender

[Atlantic 3279]

The P1 scheme was, I believe, originally drafted out as a 2-10-2 with "mineral standard" 4' 8" coupled wheels, rather than the eventually adopted 5' 2" wheels of the 2-8-2s, but that's not what I'm doing in this case. Given also that, as Bill Bedford may concur, with approximately the usual 1 in 8 inclination of the middle cylinder it appears to be impossible to accommodate Gresley's normal 3 cylinder system if the leading two coupled axles are less than 6' 6" apart, I'm not sure that ten-coupled was ever a serious possibility for a Gresley loco. The middle cylinder could of course have been yet more steeply inclined so that its con-rod would miss the leading axle, but that would have increased the syncopation of the power pulses and valve events, plus causing greater limitation of space for a boiler. I don't think Gresley or the team at Doncaster would have considered the idea that NBL implemented later on the B17s, with divided drive and the middle cylinder well-forward of the outside pair. Would it have been sensible to apply some of the piston thrusts to an outermost axle of a ten coupled arrangement anyway?

The scheme I actually have in mind featured a completely novel arrangement of four cylinders (for simple-expansion) and was being devised on the eve of the Great War, the onset of which possibly helped to ensure that any slim chance of its realisation that had ever existed was then thoroughly extinguished.

Just compared pictures with the NER Tatlow Wagon Volume and he states a 100 in total 50 by Leeds Forge and 50 by Darlington Wagon Co in 1903 and were built in total Ashington Colliery to the Blyth Staithes.The LNER version appears to be a development of the NER type.


Surprised that there has never been a kit ?? for them as they are impressive monsters

Are these the ones ?? as Graeme now mentions pre WW1 ??

No idea re Loco

[52D]

A stretched Q6 with more wheels and leading and trailing bogies. Quick stop sir Vincent spinning in his grave.

[majormagna]

Quick stop sir Vincent spinning in his grave.

No! Attach a generator to him!

Anyhow, I'm interested in seeing where this goes...

This explains that curious whirring noise in the distance...

[Atlantic 3279]

I won't leave you all guessing for much longer. That would be cruel.

It turns out that a painted picture of the planned loco appears on the internet. That's something that I did not know until this evening. A bit of googling ought to find it, and it should be recognisable as something that can be made without destroying most of the existing features of my Bachmann USRA 2-10-2 "donor" loco.

[60800]

The closest thing I've come across is this, it's obviosly a real loco, but I can't seem to find it anywhere else. What is it?

Gresley P1. Mineral locos - powerful beasts. Look it up in the encyclopedia section of this forum, click here.

[60800]

Of course! why didn't I think of that, 2-8-2 mikado Strangely, to me the P1 looks like it has a heavier loading gauge than the P2, don't know why though.

[jwealleans]

So it does. I trust a suitable train will also be forthcoming?

[Bill Bedford]

I'm enjoying these misunderstandings

I may have to build myself some 40 ton coal wagons on diamond frame bogies to go with the loco, if and when the plan comes to fruition.

Weren't these only ever use as loco coal wagons?
