Were the older Spectrum GP30s (before they were moved to standard) DCC equipped or ready?
I don't know, but am curious why you ask. Are you considering a used one from someone or just curious yourself?
Perhaps the Bach-man has the answer you need.

No. And I think they had the split vertically chassis and those are a pain
to DCC. If you are looking at one on a web site don't waste your money.
Dear Sour,
They were not DCC ready.
Have fun!
