From what I've heard SD70's are actually pretty trashed and the cost of repairs actually exceed what they are actually worth (I believe I was told one is in need of a new main gen.) They were pretty much ran into the ground their whole lives and I don't believe ever received a major overhaul.
Susquehanna F45 survivor update!
It appears that NYSW 3638, aka MRL 390, the ex-NYSW F45 that has been with Montana Rail Link since 1993 has been saved!
although it is not yet known by who, or what the plans for preservation are:

Sister unit MRL 392 is being scrapped..She did serve with NYSW for a time in the late 80's! but as a leased unit.
the fate of the other NYSW F45, No. 3636 in Utica, is still uncertain.
thanks,
Scot
