CIE carriages in the 1600 number series

[Mol_PMB]

I’m currently working my way through analysing the CIE 1969 carriage register; the copy I have has been hand-annotated with updates to about 1975. 
It is apparent but not explicitly stated that around 30 CIE-built composite coaches in the 21xx number series were declassified to standards and renumbered in the 16xx series in the early 1970s. Soon after, most were converted into luggage vans or heating vans. 
I wasn’t previously aware of this. The information in the hand-written annotations is not fully complete to trace all the renumberings, though I have worked out 1601-1610, with regard to their previous numbers as composites and later numbers as vans. 
Has anyone got more info on these vehicles, or any photos of carriages carrying 16xx numbers?

Brilliant, thanks. That solves many of the mysteries. I think there were a few more, I’ll check when I get home.

Great, many thanks! I obviously need to study IRN.

The reference to the 4000 series numbers in that second clipping is interesting. I've seen photos of some of those which appear to be former GSWR corridor stock. 4043, 4027 and 4036 are visible here:

The copy of the CIE carriage register that I have is missing the pages for 'secondary' stock which would have included those vehicles - I guess the pages were removed from the original once all the listed vehicles had been withdrawn. They're still on the contents page though.

I will be sharing all the data in due course, I just want to get my head around it first so I can share it in the most helpful manner.

The only surviving 16xx is 1633 at Dunsandle

Many thanks. There's a lot to learn from the carriage register, but equally a lot of questions posed that can hopefully be solved by reference to other sources. This will keep me busy for a while. Thanks again!

Fascinating stuff!
