If anyone's gonna tackle this...The NY&A has four GP38-2's (not counting any leasers that were/are on the line). #270, 271, 268, and 261. All of them are ex-LIRR and have the same paint scheme as shown in the link above EXCEPT for #261:

This is if you're doing this in modern times. Otherwise, in the early 2000's they held that scheme in the picture above but with a green rooftop. And #271 had a special 9/11 tribute on the sides:

I hope this helps anyone who wants to give them a try
I would love to give these a go as a personal project but I'm not so good with texturing. I do the testing for desert pacific, not the repainting

And plus we're busy with other projects.
