In an off-board conversation with a highly respected colleague this afternoon, the matter came up of "brown or bauxite" in regard to CIE / IE wagons.

Definitions on paper of what constitutes "bauxite" seem to vary, so let's put it like this.

If we take the majority view that "bauxite" is a mid brown with a distinct reddish tint, then it is a new phenomenon as far as IE is concerned, and was never used at all by CIE. The reddish shade used now is of comparatively recent origin, most often seen now as a background for painted numerals on modern stock, which (like UTA in the sixties) rarely if ever is entirely repainted. Against a brown surface liberally coated in brake dust, it looks almost red.

CIE used a mid brown, and this continued well into IE days, until - I would guess - early 2000s. Thus, anything before that, and certainly everything without exception which constitutes CIE goods stock was not bauxite, but brown.

A good source of what this looked like can be seen on many pages of colour books of the period, or among Brian Flannigan's or Ernie ("irishswissernie") Brack's excellent flickr collections.

If anyone is familiar with the bizarre collection of sidelined wagons at Limerick, there is this oddball-goods-brake van, converted for some purpose it appears never to have been used for, and with the ends removed. THAT is painted a bauxite colour - but no CIE wagon of any sort, let alone a guard's van, ever carried that colour, any more than it did LNER loco green!

I hope this helps.
