Bachmann's GP30 in Chessie System colors arrives in the company's product line in 1979. This tooling originated in the Lionel-HO line of the '70s. Both the Bachmann and Lionel GP30 models were made by Kader in Hong Kong/China. Bachmann picked roadnumber 4125 and gave their GP30 to the B&O. The B&O did own GP30's, but the 4125 roadnumber doesn't match up to a prototype.

The Chessie System roster included a large group of EMD's GP30 diesels with nearly 70 examples owned by B&O and 46 found with the C&O. The B&O GP30's were numbered in the 6900-series; the C&O's carried 3000-series numbers. The Cumberland Maryland shops rebuilt 70 combined B&O and C&O GP30's into GP30M's between 1981 and 1983.

If you're still attempting to legitimize the Bachmann Chessie B&O #4125 GP30, there is almost an answer. Jerry Doyle notes in his "Chessie System Diesel Locomotives" book, when the CSX numbered GP30's the unrebuilt examples became CSX 4100-series units. So with some stretch, the Bachmann GP30 carrying #4125 is correct for a possible CSX GP30. Below is an example of a Chessie System GP30 with CSX reporting marks and the 4100-series renumbering.
