NS 4002 and 4004 in the shops, already?

Does anyone know the cause, heritageunits.com says that their paired up in the shops for repairs? Thanks!

I would opine that a certain amount of de-bugging may be in order due to the nature of the rebuilding.

Conway is preparing them for service. Standard NS procedure.

They were already placed in service and both suffered mechanical failures while on BNSF and were shipped dead back to NS.
