The hoppers all have a similar body shape however there are differences between batches,the first batch are quite a bit higher and this is most noticeable when they are next to a second batch (AR kits) version.
So the body shape is the same, regardless of contract
This height difference is most likely because of the different bogies fitted between the different contracts as I mentioned previously, Although having said that its hard to pick even at 1:1http://www.flickr.com/photos/clp422/9757375311/
Also the cut away holes on either side of wagons where the two ends of hopper taper down towards chassis in the centre are a different shape and size on each batch.The AR kits are a nice wagon and i will be keeping mine but it will be good to build up a rake with some variation and if you throw in a couple of Casulas Cement hoopers should make a nice prototypical 80s block cement train.
Photographic evidence suggests that there are two (2) versions of this cutout you mention at the base of the hopper tapper.
- Larger cutout follows profile of hopper on PRX / NPRF (1st Contract)
- Small rectangle shaped cutout with curved ends on PRY / NPRY (2nd / 3rd Contracts)
I don't have one in front of me but (I am willing to stand corrected) I don't think the AR Kits version has any / either cutout in this location.
I suppose we shall have to wait and see what is actually to be produce from Southern Rail, at the moment all we are doing is navel gazing.
Agreed the AR kits wagon with the addition of KRM walkway etches make up into a nice model.
Agreed, looking forward to Casula's PCX model release for the same reason
