Does that include the batch of former Conrail C39-8s (8200-8213)??
As far as I know, those units were the only batch that hadn't lost a member.
They may just be storing some of the units too. They've done that before.
From what I read, NS had removed them from the computers..so they are now off the roster, No distinction was made with regards to heritage..the only C39's remaining on the NS computers are the C39-8E's.
