FWIW .... months back I inquired at Atlas about MP15's. I don't have the email and I don't remember who it was at Atlas, but I was told that they were going to do another run of them after the latest batch of SW's, which are due in March.
They were going to do new roadnumbers of previously run roadnames, but they did not know which roadnames.
That would be great! Now that I have dcc, I would grab at least 2 or 3!
nyccollector1, have you tried Norm's O scale? Not too long ago they had a BN listed
