PNC SD18m 1801
Title:  PNC SD18m 1801
Description:  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.

PNC SD18m 1801
Title:  PNC SD18m 1801
Description:  Precision National SD18m 1801 on the BN at Clyde, Illinois, November 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 sold to PNC during 1978 and put into PNC's lease pool. During 1979, PNC began having its ex-Southern SD24's rebuilt and de-turbocharged. The first five were rebuilt by the Milwaukee Road at the Milwaukee, Wisconsin Shops. All the other PNC ex-Southern SD24's were rebuilt by Morrison Knudsen. The rebuilt SD18m's were renumbered into the 1800 series reflective of their new horsepower rating, and all were leased to the BN for about a year or so. Note the blanked over dynamic brake blisters and lack of turbocharger bulge. This unit went on to become C&NW 6623, WSOR 1801, AGPX 1801.

PNC SD18m 1802
Title:  PNC SD18m 1802
Description:  Precision National SD18m 1802 on the BN at Clyde, Illinois, April 1980, photo by Chuck Zeiler. Number 1802 was built in October 1959 as Southern SD24 2504 (c/n 15600) on EMD Order 5606. It was renumbered by the Southern to 6302. During 1978 PNC acquired this locomotive and several other SD24's from the Southern and put them in a lease pool, most being leased to the BN. During 1979, PNC's SD24's were rebuilt to SD18m's by removing the turbocharger and de-activating the dynamic brakes. The first five were rebuilt by the Milwaukee Road, the rest were rebuilt by Morrison Knudsen. The rebuilt locomotives were renumbered into the 1800 series (their new horsepower rating), and retained the last two digits of it's last Southern road number. Number 1802 was leased to the BN for about a year, then went on to become C&NW 6624.

BN SD9 6150
Title:  BN SD9 6150
Description:  Burlington Northern Railroad SD9 6150 at Clyde, Illinois on an unknown day in March 1980, Kodachrome by Chuck Zeiler. Built in July 1955 as CB&Q SD9 348 (c/n 20558) on EMD Order 5399, it became BN 6150 and later BNSF 6150. It still has evidence of a steam generator. Also seen is PNC SD10 (or maybe an SD18, SD20, or perhaps SD24m, I'm not sure, depends on where you find the information, each author is different) 1852, built in September 1959 as UP SD24 427. Early in 1980, Morrison-Knudsen rebuilt five ex-UP SD24's for PNC, de-turbocharging them and disabling the dynamic brakes (blisters are blanked over), producing an 1800 horsepower locomotive. Three were leased by the BN for a time, this one was completed January 18, 1980 and became C&NW 6647 on March 31, 1982. It apears that the sand tower is leaking.

PNC SD18m 1852
Title:  PNC SD18m 1852
Description:  Precision National SD18m 1852 on the BN at Clyde, Illinois, April 1980, photo by Chuck Zeiler. Number 1852 was built in September 1959 as UP SD24 427 (c/n 25385) on EMD Order 5602, delivered to the UP with an EMD low short hood. In October 1977, this unit and four other UP SD24's (#'s 407, 416, 418, 421 and 427) were sold to PNC, later becoming PNC lease units 1848-1852 respectively. They were all sent to Morrison Knudsen for rebuilding, returning without turbochargers and dynamic brakes. They were leased to the BN for about a year, then leased to the C&NW, finally sold to the C&NW in March 1982, the pictured unit becoming C&NW 6647. On the PNC they were classed as SD10's, the C&NW classed them as SD18R's, here they are classed as SD18m's because that is what is available under Rebuilt EMD, and hopefully prevents confusion with MILW SD10's, which were derived from SD7's and SD9's.
