Hi Beast

Thanks for posting these, some great detail shots, there are a lot of transfers to apply and these will help! by the looks of things they stayed pretty clean for coal hoppers so just a heavily faded/patch painted look generally. Nice one.

Useful photos Beast, thanks for posting!

 

Readers to the DEMU forum will have seen that I am working on a rake of these based around my 3D printed LTF-25 bogie. Quick snap attached showing progress (apologies for poor quality - taken on a phone!):

Taking a break from Showcase prep, I thought I'd finish sticking transfers onto them this evening. It's now time to decide what numbers they will become. This then made me think, which numbers were outers and which inners. Looking at photos (e.g. Beast's ones above), surprisingly there doesn't really seem to be a pattern:
 
INNERS:
19604
19610
19611
19630
19631
19640
19642
19655
19664
19676
19677
19678
19681
19683
 
OUTERS:
19632
300639 (was this 19639?)
19641
19645
 
Interestingly, I can find far more photos of inners suggesting that they were much more numerous. Additionally, I can't find a shot of outers positioned buffer-to-buffer mid rake (as ARC/Hanson did/does with the JHAs) also suggesting a low number of outers.
 
Finally, when these were renumbered to HKAs I wonder, did they keep their numbers in the sequence (e.g JMA NP19632 became HKA 300632)?

I have noticed a lot have been fitted with replacement ltf bogies like the flhh hoppers from new. As to the formations of inners to outers, originally they were a ratio of 8 inners with a outer at each end (iirc). Now with the 66 having knuckles amd the outers having drop head knuckles fitted from new, they can be in any order, with outers mixed into the rakes at random.

When NP started up they did do trials using knuckles only but had major problems with the bad track in the colliery yards with too much vertical movement of the lead wagon compared with the loco during the loading process, thus they went back to the inner/outer scenario.  There was some discussion of fitting what I believe are called 'shelf' couplers but I don't know if anything came of that.  I certainly can't rmember ever seeing 'outers' mid set.

 

Obvioulsy those are all the JMA  4 bay coal hoppers, are the 3 bay limestone hoppers, which were the first set delivered, still around?

There was no obvious pattern to which were outers and which were inners. I think it was 19650 which was officially coded as having both sets of drawgear but whenever I saw it, it was running around as a standard inner.

 

While I was at Warrington, we did occasionally run the sets with the knuckle couplings at the end and the buffered wagons in the middle of the set if 66 hauled. Also if we were short of inner wagons, but had a surplus of outers (very rare) then a set would be marshalled outer-inners-outer-outer-outer.

 

They were renumbered like for like (i.e. keeping the same 3 digits at the end) when fitted with TF25 bogies and recoded HKA but IIRC only one set has been converted and the wagons were seemingly selected at random.

 

Most of the JHA limestone hoppers are still around, now coded HJA, renumbered like for like and also fitted with TF25s.

There's quite a few stabled at Dowlow Quarry, visible in the distance from the A515. I think they've been there awhile now. But I did manage to phot one last month at Peak Forest. As 40044 says, they're HJA's now.

This is HJA 300400.
