That jade green on black D.S.I. livery is a pretty one. Really would have been cool if that would have been the standard PC livery (but then the PC would have gone bankrupt even quicker with all those extra cans of green paint they'd have had to buy!

) Thanks much everybody for sharing this and the history behind it.

You can tell some of them apart by their hood designs:
The SW-1 has a shorter hood than the rest of them and a little box below the front grille. It also has bigger front windows because the hood tapers upwards a bit farther ahead of the cab like on the later SWs.
https://www.american-rails.com/e292.htmlThe NW-1, -2, -5 have a longer hood like the later SW models, but share the bigger front cab windows and the horizontal hood top section before the cab with the SW-1.
The younger SW models then have the hood design like the PC unit pictured above.
I'm not at all sure how reliable these "rules" are to identify the switchers, or if one couldn't (for example) find an NW-2 with a later SW-type hood. There are probably also other identifying features but those hood design differences is all I know.
