Clinchfield received 800 of these cars from ACF in the Spring of 1964. Clinchfield ran down the spine of the Blue Ridge Mountains from a connection with the C&O in eastern Kentucky, through the western end of Virginia, eastern end of Tennessee, western end of North Carolina and finally to Spartanburg, South Carolina. Clinchfield originated HUGE volumes of coal on the northern third of the line. This traffic included metalurgical coal bound for mills in the Upper Midwest, steam coal (for generating electricity and running industrial machinery) for the Midwest and the southern states, and export coal bound for ocean terminals all via Clinchfield’s many connections. CRR had been jointly controlled by Atlantic Coast Line (later SCL) and Louisville & Nashville for decades and would ultimately join them in Seaboard System and CSX. This roadname is coming in 12 road numbers.
