F40, he is right, go to that CSX loco site, you can search to see what units are in "Dark Future" or the old CSX paint or even in Con-rail. I believe I sent you the link before, but try it.
Just as information, where you are you will only see the 6200 series
GP40-2's not the 6900's, because they are equipped with the proper cab signal system and assigned to the Albany Division. Like we discussed last night, in Attleboro and Mansfield, you are likely to see less variety since not many of these units have the A.C.S.E.S. equipment to permit them to work on Amtrak's N.E.C.
I know for sure that the 6210, 6214, and 6223 are in Dark future.
Here is a llist of the engines that I know off tyhe top of my head that are A.C.S.E.S. equipped:
6204, 6209, 6210, 6211, 6213, 6215, 6227
