Enjoyed the review; great job with excellent quality! My Walthers GP-60 also came with Micro-Trains couplers, but seems to run more slowly on DC (speed is between Atlas and Kato diesels). My GP-60 had no black light deflector board, so I used electrical tape inside the cab to route light only through the headlamp lens. Walthers is wise to make a true DCC ready loco with easy conversion. This pleases us DC operators, as well as gives DCC operators a choice of decoders. I can see additional Walthers diesels (such as a GP-38) on my N scale roster.
