- UP 1451B,C-1455B,C were built for passenger service as UP 969B-978B; renumbered to UP 900B,C-904B,C in March and April 1948. Regeared for freight service and renumbered to the 1451 series in April to September 1953.

One of the unique features about UP's ten EMD SDP35 locomotives was their rear MU connections. In addition to the usual lower MU connections below the walkway, these locomotives had a second set of MU connections mounted up on the rear of the carbody to match the high MU connections on any following EMD E8 and E9 locomotives, which had their MU connections on their noses, adjacent to the headlight.
UP 1400 and 1402 were equipped with air sirens mounted on their cab roof, from May 1978 through March 1979. The two sirens were removed and installed on DDA40Xs 6918 and 6924.

General Notes:
- UP 1400-1409 were originally ordered to be delivered as UP 980-989, numbered after the highest numbered E9B, number 974B. The SDP35s were UP's "modern" passenger power, delivered in August 1965, just 20 months after the delivery of the newest E9A, UP 914, in December 1963.
- UP 1400-1409 had 379,600 pounds operating weight in freight service and 388,900 pounds operating weight in passenger service.
- UP's SDP35s were in storage due to the nationwide recession from June 1980 until retirement in 1985, first at North Platte, Nebraska, until September 1981, then at Yermo, California.
- UP 1409 was the last SDP35 operating on UP; removed from storage at Yermo, California, in June 1983 to protect Amtrak's California Zephyr operation across Wyoming.
- Built on EMD order number 7824.
