The LNER Encyclopedia

Good morning all

There has been some discussion on the J21 post about the GNR 3850gal tender.
I have looked for details of the tender dimensions, but can't find any.
How does it compare with the Ivatt type B tender? Does it have taller sidesheets?
There are pics in Yeadon of J3 1088 with a Type B tender and J3 4084 with an enormous tender which I guess is the 3850gal type.
Shildon is a bit too far from Surrey for a visit with my camera and any details might be welcomed by the LNER modellers in the colonies.

Looking at the pic of 4084 in Yeadon, the top of tender sidesheet seems to be higher than top of the boiler. This would indicate that the tender sidesheets are approx a foot higher than those of the type B tenders.

very difficult to scale items off photos, especially tenders when the perspective is off.

However my drawings show that the B class tender is about 3 inches higher to tank top than the 3850 gallon Stirling one.
They both have about the same size flare.

The J3's were of course rebuilt under Gresley, so would not necessarily have had new tenders, rather what was available would have been used ex works. It is of course interesting to note that some of these very big Stirling tenders were also built for use behind goods engines around the time of Stirling's death in 1896, so it would not be unusual to see one at various times.

Thanks Paul John Coffin for the info.
As you say, it's very difficult to estimate measurements from pic, especially when the loco is at an angle.
It's a very long time since I did any three dimensional geometry, and I'm pleased that I don't have to resurrect it.
Further bookworming shows that 4084 was never rebuilt as a J3, so the boiler was 4'5" and pitched 6ins lower, so the top of the boiler would be approx 8ins lower than a J3. This would make the tender appear higher.

Your info about similar tanktop heights makes things seem more logical as the 3850gal tender had a smaller coal capacity, so would leave more room for a larger tank.

PS I enjoy researching a prototype almost as much as I do building a model.

I hadn't looked at the photo in Yeadon until now but it is pretty sure that it is a Stirling "D" type, and may well be the 3850
but I cannot definitely state that, nor indeed could anyone else!

But the LRM kit for a J4 would look pretty good with the Stirling D type tender.
