It left the Durham railway on March 30 and was stored in the Midlands over the Easter weekend.
Originally No. D5613, it has been bought privately and is being inspected to determine what is required to bring it back to a full operational condition.
The distinctive golden ochre livery will be retained initially, but when repainted will take up a different livery.
