Bear in mind, folks, there were several variations of NIR livery; initial much lighter blue and current shade; two different sizes of yellow panel, also a day-glo orange rectangle, and two different sizes and styles of NIR logo on the sides! And south of the border there was also the original livery as they were all painted in USA before delivery with a non-standard darker than normal "orange", and logos on each end which (a) were slightly larger than normal, and (b) had gthe white "CIE" lettering surrounded by a white broken wheel instead of the standard tan one. Hope that's of help to someone, rather than a source of confusion!
