EMD built 90 of these medium road-switchers, which were used in both yard and mainline roles. Part of the EMD Dash 2 line, the SD38-2 was an upgraded SD38 with modular electronic control systems, HT-C trucks, and many other detail improvements. The locomotive's power was provided by an EMD 16-645E 16-cylinder engine, which could generate {{convert|2,000|hp|kW|abbr=off|lk=on}}. These units were constructed with either {{convert|3,200|or|4,000|USgal|L impgal|abbr=on}} fuel tanks and were available with or without dynamic brakes. It shared the same {{convert|64|ft|8|in|m|2|adj=on}} frame as the SD40-2 and SD45-2, which gives it a length over couplers of {{convert|68|ft|10|in|m|2}}.
