Louisville & Nashville EMD GP30 units 1025 and 1048 head a four-unit lashup at Dolton, Illinois on August 9, 1970. Both units belonged to a group delivered in 1962. They became Seaboard System 1356 and 1379, respectively, after consolidation of the Family Lines System. Both units were apparently retired before being renumbered into the CSX 4000 series. The transparency is by David V. Leonard.
