Found a post that says GECX 609 is now GECX 899:
The coal experiment didnt work..she was quickly converted back to a "traditional" locomotive..
still floating around, perhaps in lease service.
seems to be a lot of confusion about her current model designation..I have seen C39-8, C39-9, B40-8! (which is obviously wrong), C32-8, C44-9..
I think the correct model is:
built as the only C36-8 that ever existed, and is currently called a C44-9.
this page: says she is now classed as a C44-9 on the nose sticker..so that is probably what GE is calling her now.
So originally C36-8 #609, today C44-9 #899.
although there might have been other model designations inbetween the first and the current! perhaps that is why there seems to be so many different model designations for this unit..
