Hmmm , yes I saw the old thread message .... and considered it, and the topic (NR class Repaints) has not changed at all. This is not a "reply" as such but a continuation of a topic which saw a progressive update from various contributors.
I see on Flickr that a number of NR's have recently been repainted.
NR18 has gone from its unique Indian Pacific yellow / orange to the new Journey Beyond Ghan red scheme.
NR45 has new PN blue and yellow with 5 stars.
NR55 has new PN blue and yellow with 5 stars.
NR85 has had the GSR Souther Spirit green & white repainted to PN blue and yellow.
NR121 has new PN blue and yellow with 5 stars.
Thank you to the photographers submitting photos on Flickr
