EMD 16-645E3 The 16-645E3 is a four-stroke diesel prime mover developed by Electro-Motive Division for mainline and heavy-duty switching service, forming the heart of multiple locomotive models produced in the 1970s and 1980s. It links to a lineage that includes earlier EMD two-stroke designs and feeds into rebuild programs undertaken by firms such as General Electric competitors and independent shops. The engine influenced export markets serving railways such as Indian Railways, South African Railways, Australian National, and operators across Europe and North America.

Design and Development

EMD designed the 16-645E3 within corporate programs led at its Chicago and La Grange, Illinois facilities, building on the 567 and 645 family programs initiated by engineers who worked with figures associated with General Motors and industrialists linked to Samuel Insull-era electrification debates. Development occurred alongside contemporaneous projects at Alco, Fairbanks-Morse, Sulzer, and Ruston & Hornsby, during a period influenced by regulatory shifts exemplified by standards coming from agencies like Federal Railroad Administration and industry groups such as the American Railway Engineering Association. Prototype evaluation involved test beds at National Railway Equipment Company and collaborations with yards in New York City and Los Angeles.

Technical Specifications

The 16-645E3 is a V16, two-stroke-derived configuration with a displacement of 645 cubic inches per cylinder, using modular unit injectors developed after work by teams that had liaised with Cooper-Bessemer and Baldwin Locomotive Works engineers. Typical power ratings range from 3,000 to 3,200 horsepower, with governing and fuel systems influenced by suppliers like Bosch and control philosophies shared with Siemens-equipped electrics. The block and crank were cast and machined at facilities with tooling heritage connected to Caterpillar and John Deere practices. Cooling, aspiration, and turbocharging options reflect variation seen in units supplied to Union Pacific Railroad, Norfolk Southern Railway, Canadian National Railway, and Deutsche Bahn-esque operators, while electrical systems interface with traction alternators similar in design to machines from Westinghouse and Hitachi.

Production and Builders

The prime mover was produced primarily by Electro-Motive Division at plants linked to General Motors Corporation manufacturing networks, with license and overhaul work performed by EMD Export affiliates and contractors including Montreal Locomotive Works, General Motors Diesel, Cockerill, and private rebuilders such as Progress Rail Services Corporation. Export and local assembly occurred under agreements in countries with industrial partners like Henschel, MÁV, Kawasaki Heavy Industries, and Hyundai Rotem, while maintenance and remanufacturing were carried out by firms like GE Transportation spinoffs and independent shops with ties to National Steel Car.

Variants and Derivatives

The 16-645E3 spawned multiple derivatives, including turbocharged variants and roots-blown versions adapted for export orders to Pakistan Railways and Egyptian National Railways. It formed the core of locomotive families that intersect with models produced by Electro-Motive such as cab units and hood units fielded by Atchison, Topeka and Santa Fe Railway, Chicago and North Western Transportation Company, Southern Pacific Railroad, and Conrail. Rebuilds created by companies like RailAmerica and Montana Rail Link incorporated uprated electronics from suppliers like Rockwell Automation and ABB, while aftermarket conversions sometimes integrated emissions control components influenced by standards promulgated in forums involving United Nations Environment Programme delegations and regional agencies.

Service History

Units powered by the 16-645E3 entered service across freight, passenger, and heavy industrial roles, appearing on rosters of CSX Transportation, Kansas City Southern, VIA Rail Canada, New Zealand Railways Department, and numerous shortlines. They participated in interstate and transcontinental operations traversing corridors such as the Trans-Siberian Railway-adjacent networks and ports serving Felixstowe and Rotterdam. Over time, many engines were subject to life-extension programs by companies with links to Brookville Equipment Corporation and Wabtec, and some were retired or preserved at museums like the National Railroad Museum, California State Railroad Museum, and regional heritage centers managed in cooperation with organizations such as Railway Preservation Society of Ireland.

Notable Operators and Locomotives

Significant operators that employed locomotives powered by this prime mover include Union Pacific Railroad, BNSF Railway, Canadian Pacific Kansas City, Ferrocarriles Argentinos-linked fleets, and industrial operators such as Anaconda Copper-era lines and mining railways in Chile and Peru. Specific notable locomotives and demonstrators equipped with the engine saw service in high-profile contexts on routes connecting Chicago Union Station and Los Angeles Union Station, as well as in cross-border freight movements coordinated with agencies like Transport Canada and ports such as Port of New York and New Jersey. Several preserved examples appear in collections curated by institutions like the Illinois Railway Museum and private collections formerly associated with James J. Hill-era lines.
