| Precision National SD18m 1801 on the BN at Clyde, Illinois on an unknown day in October 1979, photo by Chuck Zeiler. Built in October 1959 as Southern SD24 2503 (c/n 25599) on EMD Order 5606, it was renumbered to Southern 6301. It was acquired by PNC during 1978, leased as PNC 6301 for a while, then sent to the Milwaukee Road for rebuilding. The turbocharger was removed, the dynamic brakes were de-activated, and it was returned to PNC as a 1800 horsepower SD18m, numbered in the 1800 series (the horsepower), and retaining the last two digits of it's last Southern road number. It was leased to the BN for about a year, then went to the C&NW as 6623, then WSOR 1801, then AGPX 1801. |
