The EMD 567 is a line of large medium-speed diesel engines built by General Motors' Electro-Motive Division.This engine, which succeeded Winton's 201A, was used in EMD's locomotives from 1938 until its replacement in 1966 by the EMD 645.
The "S" designation originally stood for six hundred horsepower and the "N" designation for nine hundred horsepower, although they were used for the more general designation of smaller and larger engine models after the more powerful 567 model engines replaced the Winton engines. The "C" designation stood for cast frame locomotives and the "W ...
EMD introduced their new 710 engine in 1984 with the 60 Series locomotives (EMD SD60 and EMD GP60), the EMD 645 engine continued to be offered in certain models (such as the 50 Series) until 1988. The 710 is produced as an eight-, twelve-, sixteen-, and twenty-cylinder engine for locomotive, marine and stationary applications.
The 201-A engines used in E-units were 900 hp (700 kW) V12s. Experience with the 201-A, which was the first two-stroke Diesel engine in operational use, was invaluable in the development of the next-generation Diesel engine, the EMD 567, a purpose-designed engine that achieved a factor-of-five improvement in piston life for locomotive use.

The F3 used a 16-cylinder 567B series diesel engine developing 1,500 hp (1.1 MW) at 800 rpm. The 567 was designed specifically for railroad locomotives, a mechanically scavenged, or "blown" 2 stroke 45 degree V type with 567 cu in (9.29 L) displacement per cylinder, for a total of 9,072 cu in (148.66 L). A D.C. generator powered four traction ...
Only the four demonstrator FTs used the 567 U-Deck engine. Those engines were replaced in the demonstrators by 567 V-Deck engines before sale to the Southern in May 1941. All FT locomotives built between December 1940 and February 1943 used the 567 V-Deck engine. The 567 V-Deck engine was replaced in production with the 567A engine in May 1943.
The Erie-Builts soon ran into problems with the OP engine that had not been experienced in Navy service. The 38D 8-1/8 engine as configured for the Erie-Builts Brake Mean Effective Pressure of 95.2 psi, as opposed to the 85 psi rating for Navy engines and 77 to 86.7 for the EMD 567 as used in the E7, FT and F3.

Starting in late 1948, the NW2s were manufactured in EMD's Plant #3 in Cleveland, Ohio. The locomotives were powered by a 12-cylinder model 567 engine and later a model 567A engine. In addition, EMD built three TR cow–calf paired sets, 36 TR2 cow–calf paired sets, and two TR3 cow–calf–calf sets.
