The LNER Encyclopedia

Hi,
I’ve had a bit of fun drawing this up – mostly sitting in my armchair - done minimum research so when I post my answers I think some others might have some fun finding my errors!
LNER & Constituents.
1. Only Gresley engines without 26 inch stroke?
2. Early LNER days which top link express engine had only a 24 inch stroke?
3. LNER took over three 4 cylinder types in Jan. 1922, what were they?
4. Three LNER constituents had 8 coupled engines in Jan.1922, which companies were these?
5. Only two had Consolidation 2-8-0s ,what were these classified as?
6. Gresley designed seven 2 cylinder locomotives, what were they?
7. Gresley’s standard wheel sizes were 4 ft 8 in., 5ft 2in., 5ft 8in., 6ft 2in. and 6ft 8in. only one of these was not used until 1934. Which size and which engine design?
8. Which constituents of the LNER never used 8 coupled engines?
9. Which Gresley designs were built with only two outside cylinders and which year?
10. Except for the high pressure Gresley-Yarrow boiler of 450 psi, what was the highest boiler pressure Gresley used and which classes?
11. Gresley introduced two wheel configurations that were almost unique in British tender locomotives. What were they?
12. Gresley used four main pressures in his boiler designs. What were they?
13. Except possibly for the U1 Garratt which engines had the shortest and longest wheelbases of Gresley’s designs?
14. Which Gresley engine had the largest grate area and what was it?
15. Only one Gresley authorized engine class used divided drive, what was it?
16. Gresley’s H2 (original LNER K1) was not the only 2-6-0 on its introduction on the GNR,what was the other at that time?
17. Gresley designed and built six classes locomotives which were the only ones of that wheel configuration. What were they?
18. Which constituent’s main line design was used continuously from 1911 to the end of steam?
19. Except for the U1 Garratt, which Gresley engine had the highest nominal tractive effort?
20. Which Gresley design, other than the W1 compound had the smallest cylinder size?
21. On Jan.1 1922, except for GNR types, which 3 cylinder types did the LNER take over?
22. Only five of Gresley’s engine classes used Stephenson valve gear. What were they?
23. In GNR days, how many major variants of the 4-4-2 tender engine were there?
2, 3, 5, 6 or 8?
24. in 1948 British Rail on behalf of the LNER resurrected a 19th century NER design. What was it?
I’ll post my answers here for people to correct me if there’s enough interest. Anyway in the meantime maybe you could have some fun answering them.
Regards,
Jon -(Sturrock)

- first erratum. Amalgamation was 1st Jan. 1923 not 1922 ! Maybe too much at once. Anyhow I will post MY answers for public criticism on Q 1 to 6 in the next few days. Meanwhile on reflection I've found a few other errors!
Jon.

No 16 - The Baldwins?

Sturrock: But if he said December 1921, it would have been FOUR Constituents! (the H&BR had the Q10)

11. 2-8-2 and 4-6-4

I can see some minor misleading aspects in some questions with suggested corrections:

11. Gresley introduced one wheel configuration that was almost unique in British tender locomotives. What was it?

20. Which Gresley design, ... had the smallest cylinder size?

Now that's not right at all, because 2-8-2 and 4-6-4 were completely unique to Gresley among UK tender loco designs. There actually was a tender loco wheel arrangement almost unique to Gresley among UK tender loco designs.

I look forward to the stimulating debate over the GNR atlantics, and whether all the inherited non-GNR three cylinder classes are found.

OK - here are MY answers to Q1 to 6. - here goes!
Q1. The O1 2-8-0 of 1913 had 21 X28 inch cyls. All other Gresley engines had 26 inch strokes.
- and of course (cheating a bit) the EM 1 of 1941!
Q2. The Ivatt C1 big boiler atlantic had 19 or 20 X 24 inch cylinders & was used til enough original A1 s came "on line".
Q3. The Robinson B3 Lord Faringdon and the mixed traffic B7 version ; and the 4 cyl Gresley conversion of a C1 atlantic No. 279 (3279) which lasted til the late '30s until rebuilt. (I was careful in this Q to say types not classes!)
Q4. The NER, the GNR and the GCR. The Hull and Barnsley had one but had been only just been taken over by the NER.
Q5. Gresley's O1 and O2 , Robinson's O4 and O5.
Q6. J6 0-6-0 (1911) although this is also attributed to Ivatt.
K1 2-6-0 (1912)
K2 2-6-0(1913)
O1 2-8-0(1913)
N2 0-6-2T(1920)
J50 0-6-0T(1922)
J38 0-6-0(1926)
J39 0-6-0(1926)
( and I just thought of the small 4 ft 2 in boiler version of the J50 , the J51, which were all reboilered to J50 standard by 1935 - so that makes nine so far. (I said seven!)
On Q7 to12. Soon maybe if anyone is still interested?
Regards, Jon.

Q3. +1 4 cylinder type at least, Smith's compound atlantics for the NER, LNER C8.

Thanks Hatfield Shed. I sort of confused myself a bit with this question. I actually originally thought of the V2 and Paget's thing, then i thought up the 2-8-2s and the contentious 4-6-2-2(?) My clumsy wording -sorry! - But some polemics will come up regarding "tender engines" and Garratts and the 4-4-4-4 !!! On Q20 -could answer this two ways -I meant individual cylinder size not overall cylinder capacity. But still, its just a bit of fun!

Wow, thanks Hatfield, Just noticed your Smith compound - make that four in my answer post!!!

15 B17

Q. 18 - GER Class S69 - rebuilt later as B12/3

Gee Belvoir you trumped me on that one - I had to look it up and you're right! - I had in mind another.
I'll have to change "design" to "designs"!

This thread is almost running its course, so here goes my answers for criticism for Q7 to 12.
Q7. 6 ft.2in. on the P2 "Cock o' the North" 1934.
Q8. GNSR NBR GER (later the Metropolitan and the M & GN Joint.)
Q9. After the K1 in 1912 (using the later LNER classifications), Gresley produced his last outside 2 cyl. classes in 1913, - the K2 and the O1.
Q10. 250 psi of the A4 and the V4.
Q11. Careless of me, as Hatfield Shed pointed out. Only one is 'almost' unique - the 2-6-2. Paget in strange circumstances on the MR produced an equally strange one-off 2-6-2 in the early 1900s. Check the interweb "Paget 2-6-2"). The other two, the 2-8-2 and the 4-6-2-2 W1 (any comments on this?) were unique ( unless you try to count the seemingly innumerable British built 2-8-2 s for export! The 4-6-2-2 however was, but not if you see it as a 4-6-4.)
Q12.Although he produced diagrams of 170 and 175 psi boilers early, he then used 180, 200, 220 and 250 pounds per sq. inch.

Since Q11 is restricted to tender locomotives, you are good for 4-6-4.
