The EMD FP45 is a cowl unit type of C-C diesel locomotive produced in the United States by General Motors Electro-Motive Division. It was produced beginning in 1967 at the request of the Atchison, Topeka and Santa Fe Railway, which did not want its prestigious Super Chief and other passenger trains pulled by freight style hood unit locomotives, which have external walkways. The Santa Fe preferred a cowl unit.

History and development

The EMD SDP45 was a good passenger locomotive, but to the Santa Fe it did not look the part. EMD therefore designed a lightweight "cowl" body to cover the locomotive, though it did not, as in earlier cab units, provide any structural strength, which remained in the frame. The cowl provided sleeker looks, better aerodynamics at speed, and allowed the crew to enter the engine compartment en route for diagnostics and maintenance. Final drive gear ratio for passenger service was 59:18.

Orders

The Santa Fe purchased nine of the locomotives (road numbers 100 through 108), and the Milwaukee Road bought five for its passenger service (road numbers 1 through 5). Reportedly, Illinois Central Railroad was considering an order for five FP45s as well (EMD order #5742, serial #s 34952-34956), but cancelled it. Such low production was feasible and profitable for EMD since the locomotive was fundamentally just a re-clothed SDP45. Power, as in the SDP45, was from a V20 645E3 engine (or prime mover) developing 3,600 hp (2,680 kW).

Liveries

When Amtrak took over passenger service, the FP45s were reassigned to fast freight service, especially Santa Fe's Super C high-speed intermodal run. They were soon repainted from their original red and silver Warbonnet scheme to the standard blue and yellow freight scheme when the steam generators were removed and they were permanently assigned to the freight pool. In June, 1989 two of the units, #5992 and #5998, were repainted once more in a modified version of the Warbonnet scheme (this time, displaying Santa Fe in large, red letters "billboard"–style across the side) and re–designated as #101 and #102. The units reentered service on July 4 as part of the new "Super Fleet" — the first Santa Fe units to be so decorated for freight service. The six remaining units were thereafter similarly repainted and renumbered (to 90-93, 95-98, the engine that would have been #94 having been wrecked on California's Cajon Pass and retired in 1994), and remained in this scheme (some re–lettered BNSF after the merger) until their retirement in the late 1990s, after some 30 years of service. Unit 91 was sold to the Wisconsin Central in January 1995, becoming their #6652.

Derivatives

Control stand of ATSF 98

A freight-only derivative, the EMD F45, was sold in greater numbers (86) to the Santa Fe, the Great Northern Railway, and the Burlington Northern Railroad. Amtrak bought a similar passenger locomotive based on the 3,000 hp (2,240 kW) SD40-2, the SDP40F. At least one F45 remains in service on the Montana Rail Link in the northern United States as of January 2008, and it sees regular freight service on the line.

Withdrawal

Milwaukee Road's FP45s were all sold for scrap in 1981 and 1984.

Preservation

Those that were not wrecked in service, or sold to other railroads, are on display in museums:

• Santa Fe 90: was donated to the Oklahoma Railway Museum in Oklahoma City in a non-operational state. #90 was the last FP45 donated by the Santa Fe and had resided on a RIP track for two years before being delivered to the museum.
• Santa Fe 92: was donated to the Illinois Railway Museum in Union, Illinois.
• Santa Fe 93: preserved at the Great Plains Transportation Museum in Wichita, Kansas.
• Santa Fe 95: preserved at the Western America Railroad Museum in Barstow, California.
• Santa Fe 97: preserved at the Museum of the American Railroad in Dallas, Texas.
• Santa Fe 98: was donated in operating condition less the cab's air conditioner to the Orange Empire Railway Museum at Perris, California. It is still used for demonstration runs, though infrequently because of its sheer size and slightly low compression in two cylinders. This historic locomotive has the distinction of being the last passenger locomotive ever purchased by the Santa Fe. This locomotive can be rented and operated by the railroad enthusiast.
