Not a clue, but sometimes at the Athearn site they will list the road/unit number along with the pictures, or you could try Horizon Hobby, as they are actually Athearn.
dthurman,Athearn is still in charge of production..Horizon is the Owner/distributor..
Unlike Walthers and the P1K,P2K products Athearn still retains its name.P1K and P2K will be sold under Walthers name instead of Life Like's name if I understood the Walthers/Life Like deal correctly..
