Is sublettering on its way out?

Is Norfolk Southern in the process of phasing out sublettering of locos? On photos I've seen of newer NS locos, it seems they are either just sublettered "NS", or have no sublettering at all.

I think it's been phased out - word is, no new units get sublettering.


BTW, what subletters would the OCS units get? SOU?

Sub-lettering is dead as of a few years ago.

The sublettering I beleive was due to STB/Federal merger regulations. Thats just an opinion/educated guess, but it seems to be the way the things went since anything purchased after the breakup has been stenciled "NS" instead of CNOTP, SOU, NW, PRR, or CR.

I thought I saw a photo, somewhere, of an SD70 sublettered NW - altho I guess it may have been the angle of the photography plus the lite that made the S look like a W. Other than that I guess the newest locos that got sublettereing (apart from those taken over from Conrail) were the GP60s (all sublettered SOU, I think?) and C39-8Es (I think they were sublettered around 50-50 NW and SOU?)
