407	Nov 1947	29120	Dec 1978	28 Dec 1978	(1806)	31 Mar 1982

General Notes:

a.	General Electric records show that these seven locomotives were built for Utah Copper Co. even though that company had became the Utah Copper Division of Kennecott Copper Corp. in January 1941.
b.	Built as KCC 1-7, renumbered to KCC 401-407 in May 1964.
c.	Equipped with dynamic braking.
d.	Equipped for operation on both 3000 VDC mainline voltage and 750 VDC yard voltage to allow shared use of yard tracks in Copperton yard with the 750 VDC, 700-class Bingham mine electrics.
e.	These units were operated in 2-unit sets to power the 18 daily 28-mile round trips between Copperton yard and the mills at Magna and Arthur, and after 1964, Bonneville, with a average annual mileage of 50,000 miles; between the time of their delivery in 1948 and 1964, there were two units assigned on a rotating basis to the car dumpers at both the Magna and Arthur mills, leaving five units available for road trains; the expansion of operations in 1964 required additional motive power to operate additional trains for the new Bonneville mill, so additional locomotives were transferred to Utah from Kennecott's Chino operations in New Mexico and rebuilt for specific assignment to the car dumpers, releasing all seven road units to road service.
f.	During early 1974, Kennecott studied the possibility of converting the Copperton Low grade line from 3000 VDC to 25000 VAC; both EMD (with ASEA of Sweden) and GE expressed an interest. (Pacific News, Issue 146, December 1973, page 17)
g.	During late May 1978 the Copperton Low Grade line was shut down for ten days; the 400-class electrics were replaced by leased UP GP30s 807 and 809 and new high-cab GP39-2s 779 and 780; the shut down came from lightening damage to the substation at Cypress, halfway between Bingham and Magna.

Notes:

1.	KCC 402 was donated, along with 80-ton and 125-ton electrics 700 and 771 and dump car 539, to Western Railway Museum, Rio Vista Junction, Calif. in August 1984; moved to Deseret Peak Complex near Grantsville, Utah (date?).
2.	KCC 406 was converted to 750 VDC to operate in the Bingham mine in March 1980 but was never used in regular service. The electrics had been replaced by the SD40-2s by this time.

GE/Westinghouse 125-ton electric — 3 units (Ore Haulage)
B-B; 250,000 pounds operating weight

Road Number	First Number	Builder Date	Builder Number	Date To Utah	Rebuild Date	Date To Mine	Mine Number	Notes
408	KCC-Chino 2	Sep 1954	32187!	Nov 1964	Dec 1964!	Dec 1978	(1807)	1
409	KCC-Chino 3	Apr 1958	33347	Dec 1964	Feb 1965	Dec 1978	(1808)	1
410	KCC-Chino 1	Sep 1954	32186	Feb 1965	Mar 1965!	Dec 1978	(1809)

General Notes:

All three units were built as Kennecott-Chino Mines Division units; transferred to Utah in 1964 due to expansion in operations at Bingham; rebuilt for specific assignment to the Magna and Arthur car dumpers, releasing all of the seven road units from car dumper service to road service to move the additional ore tonnage required by new Bonneville mill.

Converted from 750 VDC used at Chino to 3000 VDC used by Ore Haulage; work was done by Westinghouse in their Salt Lake City, Utah, facility; all three locomotives originally looked like the 766-773 class Bingham mine locomotives and were completely rebuilt by Westinghouse with new car bodies that included bay windows for the engineer and full width car bodies at the rear that allowed better visibility at the Magna, Arthur, and Bonneville car dumpers.

Notes:

1.	KCC 408 and 409, along with 80-ton electric 703, were donated to Boone Valley Historical Society, Boone, Iowa, in November 1985, delivered in June 1986.

Ingersoll-Rand 60-ton oil-electric — 1 unit (Utah Copper)

Road Number	Builder Date	GE Builder Number	Alco Builder Number	Notes
600	Jul 1926	10028	16680	Returned to Ingersoll-Rand and sold to Lehigh Valley.

General Notes:

a.	Built for Ingersoll-Rand by American Locomotive Co. (Alco) at Schenectady, N. Y. using General Electric electric equipment and an Ingersoll-Rand oil engine as the 12th Ingersoll-Rand boxcab oil-electric locomotive built (Utah Copper 600 was the 6th of the second group of six units); leased to Utah Copper Co. to participate in the one-year motive power tests for Bingham copper mine in 1926, testing its performance against the performance of Bingham & Garfield 0-8-0 steam locomotive number 500 and new Utah Copper battery/electric locomotive number 700; Utah Copper 600 was delivered to Utah Copper in early August 1926; the unit proved to have inadequate power to climb the grades in the Bingham open-pit mine and was returned to Ingersoll-Rand; sold to Lehigh Valley number 99 on January 21, 1932; retired by LV in September 1947; scrapped by Lehigh Valley in June 1950.
b.	See also "Ingersoll-Rand: catalyst of Dieselization" by David H. Hamley in Trains magazine, December 1970, page 35.

600	Mar 1942	15105	Transferred to Bingham operations and renumbered to 665 in 1948; renumbered to 765 in October 1965.

General Notes:

Built as Utah Copper 600; operated by Bingham & Garfield Railway as car-dumper motive power at Magna (Fogarty) and Arthur mills; KCC 600 joined 70-ton electrics 1000 and 1001 and 85-ton electrics 737, 738, 740, and 741, also assigned to Ore Delivery Department car dumper service at Magna and Arthur mills until 1948; all seven units were transferred to the Bingham mine in 1948 after the new low-grade, all-electric Ore Haulage line was put into operation; the entire electrification at the mills was changed from 600 VDC to 3000 VDC at the same; car dumper motive power at the mills was then filled by rotating single, new 3000 VDC electric road locomotives between car dumper service and regular road service.

General Notes:

a.	Built as 75-ton locomotives, re-ballasted by Utah Copper as 85-ton locomotives.
b.	Numbers 700, 702, 703, and 724 had 170,600 pounds operating weight and 33000 pounds tractive effort, and were equipped for both 750 VDC overhead and 600 VDC storage battery operations. Storage batteries were used in line relocation work in the Bingham mine where overhead power was not available. The batteries had a 500-hour running time and were recharged through the catenary. The battery feature was only used occasionally after highway trucks were adapted for use in the mine beginning in the 1930s and 1940s.
c.	One source says that Utah Copper 703 was built as Utah Copper 701. This seems unlikely because of the sequence of builder numbers. GE numbers 10640-10656 are accounted for; most are small electric mine locomotives built for use inside coal mines, all built between February and October 1928.
d.	Numbers 709, 712, 718, 728, and 730 were equipped for both overhead and cable reel operation. Cable reels were used in line relocation work in the Bingham mine where overhead power was not available. The cable was 800 feet in length and was connected at a junction box at the nearest overhead support. The cable feature was only used occasionally after highway trucks were adapted for use in the mine beginning in the 1930s and 1940s.
e.	Numbers 704-723, 725-747 had 172,800 pounds operating weight and 35,000 pounds tractive effort.
f.	Numbers 737, 738, 740, and 741 had 185,380 pounds operating weight and 55,600 pounds tractive effort, and were originally used by the Ore Delivery Department (B&G Ry.) as car-dumper locomotives at Magna and Arthur mills, joining 80-ton electrics 1000 and 1001 purchased to electrify the car dumper yards in 1924. The 80-ton and 85-ton units were joined by 100-ton electric number 600 in 1942. All seven units were transferred to the Bingham mine in December 1948 upon beginning of operations of the new low-grade Ore Haulage line. The dumper yards at the mills were converted to 3000 VDC to allow use of the larger Ore Haulage locomotives in rotation with regular mine-to-mill service.
g.	Numbers 748-760 had 169,300 pounds operating weight and 35,000 pounds tractive effort.
h.	Builder plate specifications show B+B, 150/150-4GHM818A, 750VDC

General Notes:

a.	All twelve units leased from Union Pacific and Denver & Rio Grande Western beginning in May 1973; the lease ended in December 1978.
b.	D&RGW 3014 was also leased (without an assigned Kennecott number) between September 4, 1973 and mid-March 1974.
c.	These leased GP30s were numbered into vacated number slots in Kennecott's 700-class 85-ton straight electric fleet and were assigned to haul the waste trains from the Bingham open pit mine to disposal areas adjacent to the mine.
d.	All units were equipped with raised pilots and wooden foot boards.
e.	UP, D&RGW, and Kennecott road numbers visually confirmed by Ryan Ballard.
