2250 hp on 4 wheel trucks. B&O's GP30s were built between 1962 and 1963. 

An enlargement of the photo of  B&O 4237 . #6915 is seen outside the railway facilities at East Salamanca, NY in 1976.  The GP30 was an attempt to introduce some styling into the cab and locomotive body. It created a unique design which was not perpetuated in any later locomotives.

The Chessie System later became part of the CSX System.
