What does 'nee' mean?

[Val Nelson <super-chief-val@c...>]

HI all,

I have a question that has bugged me for a long time. Whenever a renumbering
has taken place, you will often see a reference to the former history with
the annotation of 'nee' (e.g. dome-coach (ex-AMT 9486, nee-SP&S 559) ). This
issue surfaced again as I was browsing through bellsouthpwp.net passenger car
site. In all my years of reading railroad materials, I have yet to see this
term defined.

What does 'nee' mean?

Thanks,
Val
